[QUOTE="BallisticsGuy, post: 1407102, member: 96226"] This is just my method for quickly identifying loads with potential and then dialing in on them and validating stats as I go. 3 for quick & dirty grouping tendency 5 for quick and dirty velocity Avg (no SD's yet, sample too small) 10 for any-ol-time grouping tendency 10 for quick & dirty SD's. 20 for solid SD's Thresholds 500yrd & under: SD's not much more than really about 20fps for my taste, groups 1MOA or less. Over 500yrds but under 1200yrds: SD's no more than 15fps, groups under .8MOA Over 1200yrds, SD's no more than 10fps, groups .5MOA or less Standards My usual requirement for a match load is SD's in single digits, group sizing average at half an inch and no flyers. That spec gives me combos that can do anything I want of them. For horsing around, I'll shoot some pretty sloppy ammo if I don't care about hit rate. [/QUOTE]
