New Build #4 Ridgeline RD15 / Geissele 18" SPR Cut Rifled Barrel. (03JUN25) First Range Session up.

What specifically do you do to tweak the pull weight on these the triggers, do you clip a certain number of coils or something?

Maybe in another thread I'll go over it, a long time ago Bill Geissele walked me through it.

There's also tons of videos on YouTube that can also guide you.

And no, I don’t cut coils off the disconnector spring it's about selecting the proper Hammer and Trigger Springs then bend/tune for the perfect balance of spring tension in both springs.

On the Hellcat, it was not reverse engineered at all. The US used the Zero to determine what it's speed and characteristics were, then developed a totally different plane that would out perform the Zero.


Thanks for the clarification. From what I've read, the Hellcat and Mustang engines were absolute BEASTS. They were the apex of internal combustion piston engines long before car guys and racing modders discovered they can do the same on the ground. These engines were on a whole different class above the Zeros and were able to take on the early jets WAY into the late 1950s before the last props were retired and we went full on jets...

6Mm GT load. Any help appreciated.

One of the best things I did was got a set of pin gages to measure exact neck ID (after resizing brass) - and with new brass (even Alpha), you likely need to at leachildrensmercy-dr.securelinkcloud.net st mandrel the necks to get them where you want them (if they're too loose from the factory, you'll have to size necks and mandrel them again to even them out).

Most "stock" size dies that have a little egg on the decapping stem aren't going to be great at giving you consistent neck tension. Pull that thing off the decapping stem and get a mandrel die - let the mandrel set final neck ID (aka, neck tension) - alternately, later, graduate to an SAC or A419 size die that incorporates a mandrel into the size die.

The Chargemaster should be able to throw reasonable powder charges, and get you to an SD of 10 or better (make sure you keep it wiped down with a dryer sheet - they're sensitive to static). Getting down to chargest within .02+/- would be better than .1+/- from a consistency standpoint, but the CM should be able to get you a lot closer than 60fps ES. Realize, though, a 60fps ES is what an SD of 10 will get you, fired across enough ammo (3 SDs+/- should account for something like 98.5% of your results).

Is bedding the AR barrel a myth? What's the best way?

I can tell you from personal experience that bedding a barrel extension on a loose fitting upper does make a difference.
I took a Criterion hybrid with a BCM blemished upper that was kind of loose and shooting around 1.5 MOA with 77 FGM-SMKs and turned it into a 0.8MOA with the use of shims and 620 goop.
I learned the process in a gun smithing class and not on the interwebz.
That was the funniest part about all long winded replies. It works quiet well, especially when you have a loose fitting extention. Use Silicone, because they use it in head gaskets. Like how in the shit is that even remotely related. 🤣🤣

Then we get into the rant about spinning up barrels. What the fuck was this thread about again. 🤣🤣🤣

It took the US some time to recover from that huge sucker punch we received at Pearl Harbor and be technologically up to par with Imperial Japan and the Third Reich. Prior to Pearl Harbor, we had been WAY behind Japan and Germany technologically. At one point both of the Axis giants were enriching uranium fuel for future weapon development while we were still just carrying out university experiments with fissionables. The Mitsubishi Zero had been the apex fighter craft for a few years until we shot one down over Alaska in 1943 with great difficulty. That Zero crashed into the snow and was relatively undamaged, the US pilot managing to get a great lead on the enemy plane and hit it with a burst that mainly shredded the cockpit and Swiss-cheesing the occupant. From that one Zero, Northrop-Grumman reverse engineered the thing and produced the F6F Hellcat which surpassed the Zero in speed and maneuverability. From 1943 onward it was a direct straight line uphill climb for us. All of the top secret Tier 1 tech agencies like the Skunk Works and JPL, the holy of holies throughout the intense moments of the Cold War right up to this day, started during this time whose original missions were to capture and reverse engineer Axis tech.

I will also add that Kowa makes the best spotters if detecting and dealing with mirage is important to you. I tried to explain how much mirage is part of the F-class discipline when your target is 5 inches in diameter at 1000 yards. This past weekend, I shot a 1000-yard match at Bayou with my .308 F-TR rifle. I shot a 199-11X on the first match and that lone 9 was so close to the line, a heartbreaker. Surprisingly enough for this time of year, mirage was not a factor that day, and I missed having it, because the wind was twitchy and the mirage was flaccid, the b*tch. Not having my mirage caused me some problems for the next two matches and the flags were lying, as they always do. Sigh. Before you ask, yes I was at 80X on my Majesta.

Chinese state sponsored terrorism?

Now just imagine a "weather" balloon floating across all of the major farmland in the US, dumping micro-clusters full of fungus-laden biological material across hundreds of millions of acres, all while the news makes up cover stories of why the US government refuses to do anything about said balloon because "it's just a friendly happy weather balloon that got a little lost!" and "it's too dangerous to shoot down over land, it might land on a tree or something!". It would never happen, never!

.....ah, shit.


Democrats must not be allowed to win again, hopefully they can be disbanded as well. The last balloon that the media turned into a weeklong circus was one too much already. It could have done an awful lot of damage while it made two loops over our entire Rocky Mountain states and Canada. YouTube hobbyists have been building IR laser blasters for years that can instantly set a wet tree trunk ablaze from 50 yards away. There is no reason why we cannot have larger ones mounted onto select fighter planes used for domestic airspace patrols. The payload bays of any potential unidentified balloons need to be IR lased thoroughly before interception so any biological agents carried inside can be sterilized by the high temperature first, or the shootdown will scatter the stuff and cause a bigger problem.

Been enjoying these last couple of posts @Dead Eye Dick

My grandfather served on the USS Melvin (DD-680) 1944-45. He ended up participating in just about every island-hopping campaign, as well as Leyte Gulf and the Surigao Strait, where the USS Melvin was one of the ships that hit the mighty Japanese Fuso battleship with a torpedo and caused her to sink. I got to go through one of his old photo albums once, and there were a ton of photos that he took (he basically was an ammo runner for the AA guns during combat) and a quartermaster otherwise. He did finally confide some of his stories to me when I was a senior in high school and had enlisted in the Marines. I guess I earned the privilege at that point. Those photos were absolutely awesome... I have no idea where they ended up. My mom still has his uniform though neatly preserved in one of her chests.

PTSD wasn't a thing really back then. My grandfather never went to sleep without 3-4 whiskies on the rocks first. However, he was never abusive, never acted drunk, and was always such a polite and humble man. He ended up being a professor of anthropology in the California state university program, and wrote books in English, Spanish, and German (he was originally born in Germany in 1922... which is why he fought in the pacific). A Fulbright Scholarship recipient in 1962-63. I just looked him up on their website, and there is his name. Awesome man.

Thanks for that Deny. I wonder if the glass is similar to the floride Ed that Kowa uses, which is known to be among the best money can buy.

I spent a summer at atterbury before going to Iraq and that place is brutal that time of year. Mirage in an ACOG was nasty at 300m so I can only imagine at distance.

I have a new ZCO 840 getting delivered next week but it sounds like I need to snag one of these new March PRS scopes to give a spin. The mirage was horrible last weekend with a zco527.
Kowa is unique it the spotter world because they grow their own pure fluorite crystal glass (CaF2, one calcium and 2 fluorine atoms.) CaF2 glass is somewhat fragile and subject to environmental conditions (heat and cold). The Super ED glass used by DEON has a lot of fluorite crystal in the formula but is also formulated to resist changes in the environmental conditions. This is explained in detail in news items at the marchscopes.com website. The Super ED glass in the 5-42X56 HM, the 10-60X56 HM, the 4.5-28X52 HM and the Majesta is made with that glass.

The F-Class Nationals at Atterbury were an eye opener in terms of mirage at 1000 yards. My 10-60X56 HM stayed at 50X that morning and I scored a 198-10X, highest X-score for that match, but only good enough for fourth place. Sigh. Only way to do that was with the 10-60X56 HM.
