[QUOTE="GuroChris, post: 1995220, member: 113578"] I've been working on some load development for my Remington 700 .308 win. I did the 10 shot powder charge test. here is a photo. [ATTACH type="full" width="179px"]218236[/ATTACH] I found a couple flat spots in the velocity chart so I loaded up 5 each. At the low end I got a decent group but lousy ES and SD numbers. [ATTACH type="full" width="184px"]218237[/ATTACH] At the higher end I got a terrible group size but pretty decent ES and SD numbers. [ATTACH type="full" width="183px"]218239[/ATTACH] The load data info is in the photos. I'm not necessarily looking for the Highest velocity I can get. I'm more concerned with group size/precision since I don't shoot past 400 yds all that much. I'm stuck with mag length or shorter for seating depth. Is seating depth testing really going to help me make a silk purse out of that sow's ear? And what increments are standard practice for testing seating depth? The bullets are 168gr Sierra MatchKings.
