OK Creedmoor fans... what's working good for you. I've got one of the Ruger Precision Rifles and I'd like to know what's working good for those loading for the round.
I've tried H4350 (42.0 and 43.0)with the 140 A-Max... my rifle simply will not shoot them or the 140gr SST, even tried IMR 4007SSC which that load shoots great out of my LR-65. Best I got was 1.10" 5-shot group.
Tried some older Sierra 140gr Spitzer BT's today with 41.0grs H4350 and they did well for a hunting bullet. Two 5-shot groups went @ 0.700" and 0.800".
I have some 130gr Berger hybrids and some SMK's in bound, going to take a break with the 140 A-Max for now.
