Yes, I have SW4350 and also Precision. My testing shows that it's actually slower than H4350. It's probably more closer to RL26, still hadn't found max charge weight. The SW4350 SD & ES were somewhat larger, but the the group size's were the same if not better.
Tested in my 6.5 Creedmoor "Test Mule" Savage 10FP, Take-Off 26" Savage light varmint. Starline LRP brass, CCI-BR2, Hornady 130-140 ELDM.
