I have started using H322 and love the way it meters... really nice and consistent from load to load...so far I have'nt went beyond 2150 FPS w/ 290 LFN BTB am going to try it with 250 LFN BTB for LESS recoil...has anyone seen much "leading" in their barrels at around 2300 FPS...using the 250 BTB (.432)...am getting hung on the 444 as my new go to round...only wish I new it 30 years AGO...GC HC bullets are truly amazing all my jacketed ones may get dusty...thanks for any input !
