[QUOTE="Bart B, post: 1142423, member: 5302"] I've been called every bad name in the book for not working up loads. Just used what the match winners and record setters use. My ammo tested as accurate as anyone else's. Sometimes I won a match with it. But only when the barrel's groove diameter was smaller than bullet diameter. If it's larger, good accuracy will be hard to get. Use a 2% change between charge weights. Shoot at least 20 shots per test group. Any less is statistically insignificant. Little difference in accuracy between new and proper full length sized cases. Neck only sizing rarely produces best accuracy. [/QUOTE]
