I agree with Methow Packer, I load for 3 Henry 45 Colt rifles and 3 differant Ruger revolvers in 45 Colt. I love the IMR 4227 in these guns, very accurate for me using both jacketed and hard cast. Fills the case well. My "pet" losd is 20 gr behind 255 or 250 gr bullets. Just start @ min and work...
