[QUOTE="Mike6158, post: 361787, member: 1039"] Thanks for the clarification Bryan. I've seen similar info in your book and the LB help files however the "under stabilized" text in the program threw me off. I'll keep this post in mind in the future. My 3,000 fps comment resulted when I incremented up the mv value in the program until the program gave me a stabilized indication. I applied "if they sell them and they indicate that they'll work in my rifle then maybe 3,000 fps is possible" logic or illogic to the result. I asked "if" with no real plans to try to achieve 3,000 fps. The Nosler manual generally lists the most aggressive loads and they didn't come close to 3,000 fps for a 180 gr bullet. They don't even list a 190 gr bullet. The top of my box of 210 gr VLD is scratched so the recommended twist rate wasn't apparent. I went to the Berger site and found the twist rate there, which pretty much eliminated the 210 gr bullet from my tests. I only made one round hole. My .308 has pretty good cold barrel manners so I was happy with the shot. I was looking for max load and the slightly flattened primer that I got was enough for me. The bolt was not stiff. The case did not grow (just resized it). All in all I think I'm being fairly conservative but this is MY test and I don't recommend anyone follow "internet advice" nor is this or any of my posts "advice". I've backed the max load value down to the load that I shot. The original max (my number not from a manual) was 50 gr's. My test shot was backed down from my selected max. For what it's worth I doubt if I could get 50 grains of 4350 in a .308 case. 48.5 was a compressed load with very little room. Onward through the fog [/QUOTE]
