I am looking for load data for the .41 Mag. using PB powder. IMR has in the past listed it. Can anyone help me out. Thanks, Richard

it would seem that PB has a burn rate to fast for the .41 Mag. IMR-4227 has served me well alone with the Sierra 170 JHC

Going thru an IMR brochure dated June of 2000, I find PB listed as:
170 Gr. Sierra 11.3 gr. 1460 fps 40,000 cup
210 gr. Remington 9.7 gr. 1265 fps 40,000 cup
210 gr. LSWC 9.0 gr. 1260 fps 39,300 cup
Hope this helps
