How much does case weight variation actually affect accuracy? I've been searching, but haven't seen any real examples.
I'm loading for a 338 Win Mag, using 250 grain Sierra Matchkings for target shooting. The gun is a Rem 700 with a Shilen barrel.
I weighed 100 sized and trimmed cases, Remingtons, all from the same lot, and came up with 5 grains variation. Most fall within 2 or 3 grains of each other, but there is no number that is found way more often than another.
Any advice or experience with case weight variations is greatly appreciated
