[QUOTE="jeremy.b, post: 2261767, member: 108117"] More testing with H4350 Tikka T3 xcaliber 270 win 1-7 twist, 24" done by Crown Ridge 139gr AH Win Brass 1x fired, neck turned, primer pocket uniformed, trimmed & full Length sized 3.388 COAL 1/8 turn crimp LEE FCD CCI 200 primers 78 deg F. Resume Ladder: [LIST] [*]57.0 3193 - [B]Blown Primer?![/B] Guess I found max already! [/LIST] 56.2: 5 Shots. Pulled one shot, 4 remaining shots = ~0.3" group. [LIST=1] [*]3155 [*]3164 [*]3150 [*]3158 Faint Ejector [*]3160 Slightly heavier bolt lift (no ejector though) [/LIST] For what its worth on 5 shots: SD = 5.3 ES = 14. Looks like 56.2 is a touch hot still, but seems to have decent velocity uniformity and definitely has fantastic accuracy. For today I'm considering the following options (I have ~2 lbs of each of these powders): [LIST] [*]Hybrid 100V: 55-55.5 for ~3130 [*]Staball 6.5: ~55.5 for ~3100 [*]H4350: 55.5 for ~3125 (lower edge of the node tested today) [/LIST] Staball & H4350 are likely the first test due to their temperature stability. We'll see though, maybe I'll get the wild hair to find the top end of RL26 instead! [/QUOTE]
