Most brass too short. Trim them all?

[QUOTE="Lonewolf74, post: 1389564, member: 96274"] I wouldn't worry about trimming them. Chances are your actual chamber length is .050-.070 over the 2.620 book max length (typical of saami 300wm chambers). My 300 is this way (I measured with a plug seated in a modified case) so I trim once to 2.620 when the brass has grown past that point to square and uniform case mouths then I don't trim again (unless brass grows to 2.670 which it will probably get scrapped before that happens). So with this rifle i have brass measuring from 2.610 to 2.640 and it all shoots the same and is a consistent sub 1/4 moa. [/QUOTE]
