[QUOTE="nealm66, post: 2566638, member: 114809"] I’ve always thought the pressure can vary depending on a few things. I believe Roy weatherby figured out a lot of jump can allow more powder with less pressure but there needs to be good neck tension to avoid secondary pressure spikes when the bullet meets the lands. I’ve also been lead to believe that if jamming, to use a low starting point. I usually do my pressure test 20k from jam and allows me to work in or out for seating ladders and I run 1-2 grains below what I deem as max which allows me to fine tune with .001-.002 ladder if I choose. Hope this helps and is accurate info [/QUOTE]
