Why do people load so hot?

buddy of mine was able to jam a 3" shell into a 2.75" chamber and it blew the receiver in half. Not ideal.
I know somebody that used to shoot 3" shells out of a model 12 Winchester. When I pointed out that the gun was not made for 3" shells, he just said, "but they fit"

He and the gun both survived. And he no longer shoots 3" through it.
 
I'm not too new to reloading but only really getting serious into rifle this year. If I were to read the forums, here and elsewhere, it would seem that the method to work up a load is to start in the middle of the data and then work up until your gun starts doing fucked up things to your brass. What's the deal with this advice? It clearly ignores the measured pressure limits, it's likely not going to blow up your gun but it will reduce brass and barrel life and likely reduce your precision. Is it just the natural tendency for monkeys to max things out to the point that they break? Why don't people just go to a larger cartridge if they want to stuff too much powder in? What am I missing?

Because I want to go fast.

I wake up in the morning and piss excellence.

If you're not first you're last.

On a less flippant note, I will take the highest velocity that remains accurate, doesn't display pressure signs like extractor swipes and hard bolt lift, and gives consistently low SD's.

I need all the help I can get with my inferior wind calling ability and hot dirty speed does seem to help.

Now if I could just get more velocity out of VV N555 in a 6.5CM I'd be all set since I have a bit under 8lbs of the stuff. Out of Alpha small primer brass I am getting a hard bolt lift within 1gr of listed max load, and I'm not getting to 2700fps with 140gr ELD-M. Nice low SD's though and every group was right around .5"- .7" for 5 shots. I will try this under some 147's and not push them, just enjoy nice low SD's and hopefully a nice accurate load.

Meanwhile RL 16 in Lapua large primer brass at max load shows no hint of pressure, bolt opens easy, brass looks good, SD's are single digits, and it's averaging 2956fps... and shooting small groups. A max load of the same powder under a 130gr ELD-M is yeeting it out there at 3009fps, shooting small groups, and giving single digit SD's. Damn magical unicorn powder.
 
Some people load hot because they just like to tweak ammo. They like to stretch the edges of the practicality envelope just because they can. Others are looking for their personal individual hot loads for whatever different types of game they hunt...a load for pigs, a load for deer, and on and on. They just don't think factory stuff is good enough.
 
Why do people hot rod cars, it's the same question.
If you don't get it, you probably won't ever get it, & it's not for you.
Yes the question is why do people push things until they break even though there's a perfectly good version with 95% of the performance that will last longer and work better? It's not about "getting it" I just think some people follow instincts rather than rationality and it's pretty silly to me. I wrote this post originally because I was honestly curious if I was missing something but after reading the responses here, it's clear that there is indeed zero benefit it running your gun at 10k over pressure, even if you aren't getting "pressure signs".

For the average daily shooter, the majority even, there’s more downside than upside, but as clearly stated in a number of posts above, there are those that do find the trade off worth it for their purposes.
@lash gets it.
Many shooters have no viable need to burn 3 barrels a season or even rule the local club leader board.

Then there are those at a high level of competition (not me) that do to make it on the first page of the event let alone leader board.

Some of us just like to see where our skills place us occasionally for personal goals.

I'm going to load hot enough to get the job done and not anything more .

Trick is to decide what the job is and don't kid your self about your place in life.

You and your barrel will live longer.
 
I just now ordered a new barrel with two goals in mind.

A hit on 2 inch targets at 500 yards and a hit on 1000 yard targets. Both on an ar 15 platform.

Had a bad 6.5g barrel and being replaced with a "ridiculous" 24 inch 6 arc so I can get enough speed to get the job done without burning it up while practicing.

Competitive not so much, more of a hit or fail goal.

My reality has come to bear.

Some people dont think twice about sticky bolt lift and piercing a primer now and then. I dont understand why someone would want to deal with the temperamental nature of such loads over something that runs like a top without hiccup in all conditions but it probably works well for them lots of the time.

Some people still think they "have a fast barrel" and it's not pressure..

Some people think they aren't at high pressure because their Alpha/lapua SRP brass doesn't show blatant pressure signs when they've got a nice clean, dry chamber.

For some folks, its kind of like creating some obscure wildcat that does basically the same thing as existing cartridges with head stamped brass and dies, they just like to eff around with it or nerd out about some tiny marginal improvement.
 
If someone is talking about seeing how much boost they can run through a bone stock junkyard 5.3 and your first thought is "that isn't rational", you are 100% on the spectrum.

Some people just like to push limits to see what they can do. If you have the means and resources, it can be fun.

In reloading, yes some of those people are trying to win the Darwin awards because they don't fully understand the math of what is happening next to their face. But I bet most of them push the limits gradually instead of jumping straight to an internet load that is already at 80k in a specific rifle.

The guy who taught me about reloading loves to talk about his box of pissin' hot flamethrower loads, but the majority of their shooting loads are much more boring.

I haven't read any post above here that explains why loading higher pressure is better. So you are saying that there is an inherent advantage to loading higher pressure vs achieving the same velocity in a larger cartridge? Because that's the only thing I think doesn't makes sense. For instance if someone really feels like they need a 105 berger to run at 3k you think it's better to run it in a 6br at 75k pressure vs a 6gt at 65k pressure? Obviously that doesn't make sense, there's no inherent advantage to higher pressure, there are only downsides. You really gonna argue about that?

I definitely do have those thoughts lol my buddies are all into choppers and LS swapped vans and they are certainly fun, but fun isn't
rational". You may get a higher top speed but you also blow your motor after 5k at the drag strip. I have a mostly stock 93 Dyna that never breaks down and actually has suspension. Like I get the fun of building a motor but I've also wasted years of my life on bike trips waiting for peoples bikes to be picked up...

It's actually a pretty good analogy though, for every hot rodded LS there are 10 7.4 liter trucks that go 300k with 500 hp stock. So yes, the rational thing to do is to choose the right tool for the job. The fun redneck thing to do is dick around with what you have, and anyway building motors is a lot more fun than putting too much powder in your case.

yeah this is kind of what it comes down to for me... Im also a rational thinker like you, but do love pushing for high scores where possible. Just not sure if its worth it next to my melon.

My take on root issue behind this topic is a lot of reloaders (not all) believe they are perfectly safe because they are only starting to see pressure signs every now and again. They might see max pressure is 62k and assume that pressure signs start at 62k-65k.. Well thats not too bad so they call it good. Math says they are likely going to 75k-80k+, but they don't know that.

As long as a catastrophic failure harms only the person pushing pressures that high, I dont care what they do.
 
Another thread that I read with a phone, but needed a keyboard to respond properly.... I hate typing on those infernal phones.

There is a lot to digest here... so I'll throw out a few musing on some of the things I've read in the thread... and based on precision (and pliniking) reloading for about 45 years now... Including wildcatting, making cases, casting boolits, etc.

First, I saw the mention of 'lawyer loads' or how loading manuals show lower charges than they did decades ago. I'm fortunate enough to still have my loading manuals that, in some cases, date to the 1960's. With my pen-written notes in them and in some cases manuals I 'inherited' with others pen-written notes in them. And I will say that 1975 vs. 2025 manuals DO trend downwards in max loads. At a time when materials science, engineering, barrel technology, etc. are trending to more strength and the ability to handle more pressure. This may be for 'liability' reasons. It may be that powder formulations (chemistry and manufacturing processes have improved in 50 years, too!) may make powders more efficient. Measuring technology may be better and give better insights into pressure. Or components like cases and primer cups may have evolved for various reasons causing reloading manual 'authors' to recommend lower loads. So I can't say 'why' they are lower.

But when I am starting loading for a new cartridge or bullet weight, I don't just look at my 2023 reloading handbook (my most up-to-date) but I look at about 4 handbooks. And will often look online as well to see what their load numbers are for a given powder, bullet, primer combo. The more data points the better. I almost never look at what the cartridge case is. Because much of the data is for pretty generic cases and I'm often reloading strange stuff... ranging from custom-made cases to BMG to wildcats. Or military cases.

My loads always start well below max. For one, max is rarely the most accurate. Not 'never' but rarely. Second is that starting low lets me build up and watch for pressure signs and back off or say 'enough.' Signs I look for are pretty standard... hard bolt lift, flattened or cratered primers. Sometimes just load 'feels' not right. And usually too fast = not the most repeatable/accurate. So why would I even bother going near max loads. To quote, I think, Townsend Whelen "Only accurate rifles interest me." Big booms and maximum velocities are often an anathema to ultimate accuracy, so I just don't go there.

That said, especially these days there are folks who have 'reason' to go there. The ELR game is defiinitely changing people's perceptions of how cartridges need to be loaded and is as much a 'new' form of wildcatting as everyone playing with shoulder angles and case capacities in the 30's through the '50's. As I have said here, we are in a new "Golden Age" of wildcatting.

Competitions that require flat-shooting UKD targets. Extreme-range hunting (like prairie dog shooting back in the day spawned a revolution in flat-shooting high-pressure small calibers) for big game is also influencinig folks to push pressures and max limits. And new gun designs and barrel designs, metallurgy, case shapes, powder formulations, etc. are pushing pressures up... because they allow pressures to move up.

I've been saying for several years (and I know several folks who are echoing this, such as John Baker whose Structured Barrels are a neat new addition to shooting) that pressures are the next frontier of the precision rifle world. IMHO, we are going to see much higher pressures. In fact, we already are. Not long ago, the 6.5 Creedmoor was running about 60,000 or maybe a bit more PSI (I think in CUP -- Copper Units of Pressure still... but will talk PSI here.). That was considered HOT. But new military small arms cartridges like the .277 Fury (Sig developed a few years ago) are putting out 80,000 PSI in Hybrid cases (see other thread on hybrid cases here... it's interesting) And I don't think it will be long before we see some cartridges graduating from laboratory and into shooters hands... probably here on Snipers Hide... that are over 100,000 PSI pressure. Certainly the barrel, receiver, bolt lockup, case, etc. technologies exist to support such pressure. All that is needed is the demand for them.

First demand probably won't be the .mil or .le communities, but the competition community where a flatter-shooting, longer-range round will make it easier for competitors to gain an edge on UKD or ELR targets while minimizing scope adjustments or even eliminating the needs for prisms, extremely long vertical adjustment on scopes, etc. And the wildcatting community (if not the sporting arms SAAMI community) will be there pushing it.

All that said, for the average and ESPECIALLY the beginning handloader... hot loads are not your friends. They beat up you and your gear. They are rarely as accurate/repeatable as slightly slower loads. And there is a lot more room for error as you learn the craft of making really, really good precision ammunition to feed your rifle. So follow the LATEST reloading handbook numbers. Use others as reference if you are lucky enough to have older/other manuals. Use "Internet" data, but run it against the published factory data. Even the little pamphlets that some powder producers offer in lieu of 'full manuals/handbooks" are useful. Put all that data into your notebook (You DO have a notebook, right? To record everything in? Right? A Paper Notebook? That goes to the range with your databook??) and work your load from below max to find the sweet spot for your gun and your style of shooting.

That's basic beginning advice for anything! Before graduating to Formula 1, hopefully you master a go-Kart or an open wheel!... The same in reloading. Crawl, walk run.

BTW, I started reloading .38 SPL's by the hundreds as I was an early IPSC competitor in the 1980's before it got 'serious.' I used a Lee Load-All and hammered every cartridge into the die (with a hammer) and building my rounds that way. When I moved to a $23 Single Stage Bonanza Press as a high school senior in 1983-ish... it was like I'd suddenly joined NASA! Used that press exclusively until I expanded my reloading setup dramatically beginnnig in 2005... with a second press and a BMG press. And taking it to its ultimate level (see the reloading room thread) in 2014. In 2005 was when I got very, very bit by the precision rifle bug. And began to alter my loading from volume plinking, pistol and low-volume hunting rounds... to one-holers. (Plus a few years working in weapons development at GD was a PhD Education in small arms tech.)

Anyway, this is another interesting thread and has certainly brought out the 'point/counterpoint' nature of some of the discussions. But the OP had the right idea when he asked about Max loads. And hopefully there is some good info here to help guide his (and others) forays into handloading.

I like to say, too, that the reason I like shooting, especially precision shooting, is that it is one of the most pure, 'no-excuses' sports there is. It is you, the shooter, against physics. Period. It's not against other people. Or the weather. Or the game. Or anything else. It is you against physics. Because it is understanding the physics of internal, external and terminal ballistics that lets you put your round on your target a 'whatever' range. And do it again. And again. All those outside factors (wind, weather, mirage, heat, spin drift, etc. etc. etc.) are variables that YOU the shooter must master. And are all things affecting the relatively simple physics of bodies in motion. You must be master of them all. And when you are handloading, you are mastering a core part of the equation. Internal ballistics. And removing excuses (bad factor ammo, didn't fit my chamber, too much jump to the rifling, blah, blah blah) As a handloader, you are eliminating those variables/excuses one at a time. Using what amounts to the shooters version of the 'Scientifiic Method" which is hypothesize, experiment/test, analyze data and try the next thing.

Nothing is more satisfying than a single hole made with a rifle you built (or designed/spec'd for those without lathes) and a round you loaded. In conditions that you mastered. It's why shooting is such an utterly demanding cerebral sport... if not the most physical.

Hope this helps... I am sure I am forgetting something I wanted to mention. But this is getting into TLDR territory. So I'll just stop for now.

Cheers,

Sirhr
Not TLDR. Very valuable.

I’m not going to argue at all. I was just telling you that you don’t actually understand what you think you do. You will obviously load how you feel is correct and for you that won’t be wrong.

Like most situations, people read and see what they want to see. This is no different.

bro this isn't church, you can just say what you mean and not beat around the bush and hand wave. I'm here to learn, so what exactly is the advantage to loading high pressure vs. bigger cartridge/slower powder?
 
You have nothing to actually say, got it. What a waste of time
You are just looking to argue. All that needs to be said has already been said. I cannot help that you have no reading comprehension. Now you are just trolling.

Yep. And the best way to understand another's motives? Ask him. Don't theorize about it without even asking the person you theorize about. Might be a long conversation in which you learn the other guy's POV is just about directly opposite your own, and you might have been thinking "nobody thinks this way."

Hell it made sense when I typed it, thought I was summarizing the thread, all the theorizing about why someone else "loads hot" when the big distinction is, who is loading hot what is hot what does that guy know about mechanics/combustion/tolerances...

Also the point you made, most people look for a mirror of themselves, vs finding out what the other person thinks and why.
