[QUOTE="Bart B, post: 838123, member: 5302"] [b]Re: Choice of long range test loads based on overall group size or vertical group siz[/b] I think your group's windage spread was caused by wind. But it looks pretty good if only 2" high at 600. 39 grains of H4350 is 6 grains below max i Hodgdon's data showing 45.5 grains shoots a 140 grain bullet out at 2720 fps. Your load may well be close to 2600. The folks I know winning matches and setting records with the 6.5x.284 in high power matches all full length size their cases and get better accuracy than neck only sizing them. That aside, a 2" x 5" 600 yard group with 12 shots in the wind ain't too shabby. If it can be repeated, then by all means do it. [/QUOTE]
