[QUOTE="Larry Morgan, post: 2825491, member: 4676"] I hand trickle my .223 loads to +/- 0.02gn, as low as the gempro 250 will show. I'm sure after errors and drift it's not truly that tight, but hey. As we've talked about before, I've begun to think about neck tensions. You seem to have similar experience with Federal cases. The neck tension on them was so inconsistent I didn't bother shooting for groups because I knew it'd just make me mad. They are for plinkers and foulers now. I've had good results with mostly unprepped brass. Although that term might be subjective. Virgin winchester brass, trimmed to length (although they were inconsistent enough that some were under my nominal trim length) , and sized for my chamber netted just under 1/2moa in my factor barrel 5r remmy. Cheapy win primers and the venerable 69gr SMK. I haven't gotten into weight sorting brass or bullets. Maybe some day. RL-15 is a killer .223 powder if you can find it. Fast and consistent. It won't straighten out in my gun until I get within .5gr or so of max. No pressure signs, quick, and tight. [/QUOTE]
