In my incessant addiction to seeing how cheap barrels can perform with hand loads, I recently picked up a blem 224 Valkyrie upper from Palmetto State Armory for $350. My friend 8208XBR and I tag teamed a set of (all Sierra and all HPBT except the 65, with was a spitzer game king) 95, 77, 69, and 65 gr. bullets. Here are my group sizes followed by bullet grain. Super stoked! I need to get a chrono and see what those 65 grain SSBT's are doing, would make a find ground hog round! I would confirm as well that 90+ grain bullets are seemingly not running well in a 1:7:
1.3 - 95
1.6 - 95
0.73 - 69
1 - 69
1.2 - 69
0.56 - 77
0.8 - 77
0.87 - 77
0.84 - 65
0.73 - 65
1.3 - 95
1.6 - 95
0.73 - 69
1 - 69
1.2 - 69
0.56 - 77
0.8 - 77
0.87 - 77
0.84 - 65
0.73 - 65
