[QUOTE="longrangehunterII, post: 785423, member: 61185"] Hey Thanks AZShooter, I am by know means going to imply I am an expert, and Bryan Litz is a smart guy. I've read a lot of his stuff, and agree with his statements and findings. Part of the reason I mentioned about keeping the bullet close to the lands and then chasing them as the throat wears has been the wisdom of more then a few benchrest shooters, and Bryan himself stated that would be best at the Shot Show when asked about loading his new line of bullets, and finding a seating depth that works. Here's an article by a guy that shot more then a few matches that I've also followed his findings and have used in my previous test with my 7mm-08 for shooting out to 1,000 yards.
