Outside of overpressure signs ranging from primer signals to hard bolt lift the ONLY relative measure of pressure is velocity. But it is not a "perfect" correlation to pressure. Some barrels are faster than test and some are slower. Also you may not be at maximum pressure at a loading manuals...

Assuming the barrel is free floated in the old and the new the load shouldn't move much. If the stock isn't free floated now and will be free floated in the new mounting then the charge could change, maybe a little or a lot.

I run Lucas and have used Hornady in the past in Lizard Litter (from Pet Smart) without any issues in a vibratory tumbler without any issues. I suspect the Lucas would work well in corn cob but haven't tried it. OP, it sounds like you may have added all the polish in one spot as opposed to...

Great example. I assume the target is shot at 100 yd.

I see your point and I agree with you. But I have a suspension that more people see it from the jump aspect as opposed to the other end of the bullet.

One of the more thorough, statistically reasonable tests that have been done on the subject is here: https://precisionrifleblog.com/2020/03/29/bullet-jump-load-development/ Its a multi part series and it is bullet specific but I does a good job showing what can happen with seating depth and...

^^^^^ or a V4 and FX-120i!

Since it's primed I would load and shoot. Don't worry about the Headspace on the first firing. If the necks are mangled you have to decide whether or not to try and carefully resize the neck, without a recapping pin. Or here is a thought, get a good case gauge.

What Seth said. But I will add this. The internet is not your friend as a novice, rookie reloader. There are many nuances to this process and reading too much will lead you in to confusion and conflicting processes. If you can purchase a good reloading manual. I recommend Hornady or Lyman...

Stability is a function of gyroscopic stability just like a top. It's all about spin (RPM) which is determined by twist and velocity. RPM=V*720/T, V=velocity(fps); T=twist (in/rev). The stability calculators do this for you. You simply enter twist and velocity.

I'm no Dasher expert but based on some info from some "experts" that freebore works well with bullets of 105 gr and higher. It's a little long for lighter bullets.

10 year old thread. As for 2000MR it awfully slow for an AR unless you get into the heavies AND a 24" barrel. I would not recommend it in anything other than a rifle length gas system. Also, Powder Valley recently posted this...

Old thread but 12 twist and 168 SMK is fine at 2400 fps, Sg is 1.528 at 20F, sea level.

Stockpiling is defied by whatever reporter is covering your story. Might be more than one gun, one round of ammunition, and absolutely more than one magazine. I can only imagine what they would do with 10,000 primers!

I found some LRP data in Lyman's 49th but nothing on SRP.

I agree. As I said, I think #1 is more CYA than material. I don't know if anyone has run multiple control tests and I sorta doubt that the results would ever be 100% conclusive. I can't find the SRP data. I'm thinking it was on German Salazar's blog but the may not be correct. I'm going to...

@lash This is related to #1. https://www.rifleshootermag.com/editorial/critical-factors-affecting-rifle-chamber-pressure/83492 I have seen a test on SRP and the difference was more extreme.

Mike, Hope the coffee didn't get cold. Let's drop this back and forth as I think we have some miscommunications that would take a lot to clear up. But I do want to make a clarification on one. Original Container referred to in the NFPA storage in residences or in commercial/retail display of...

I would speculate that since this is in conjunction with powder and Ramshot is suppling load data that this is a legal cover for deviation from the published load data. #5 is not a rule. It is written as a recommendation. However, you must be aware that there is a trend in bench rest and F...

It is not at all unusual for NFPA requirements to include requirements from other sources and vice versa. This often true with Engineering codes or standards adopting regulatory requirements or regulatory agencies writing code requirements into regulations. In this case transport and storage...
