I am by no means an expert but do understand, so I think, of how seating depth effects pressure.
So please correct me if any of this sounds waaaayyyy off.
1) a bullet close or into the lands, depending on if close to max load, can and will produce pressure signs. Bullet doesn't get a running start so peak pressure is hit immediately. I would think either backing off powder or seat deeper into case would resolve issue.
2) backing off the land with same charge could produce lower pressures. Bullets has a little wiggle room for jump so pressure is slightly drawn out rather than instant. Sounds good in my head.
3) I would also assume there is a middle ground between too close to the lands and seated too deep in the case. Bullet impedes powder column, even though there is say .120" jump, but compressed load would cause pressure.
4) I have some WW brass, RP, FED, Nosler, Hornady. Mostly RP by a large portion and good bit of WW. The WW brass holds more grains.
So, is it safe to say that I will have less pressure given the same parameters of powder charge, seating depth in WW brass when compared to the RP?
5) what is meant by velocity = pressure? I do have a Garmin but mainly just record my velocities for
I hate to be asking all these questions, just trying to understand. I have been loading for several years now, but want to expand my knowledge because my son wants to get involved.
