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.
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.
At the higher end I got a terrible group size but pretty decent ES and SD numbers.
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.
