I currently am using Alliant 2400 for my Beowulf loads but I am down to just over a pound and Alliant powder is hard (for me) to get. I have a good supply on hand of IMR 4227 that I use for my 300 BLK and I see IMR 4227 is listed on AA website but not for the bullet I am using.
Anyone using IMR 4227 with 335gr Rainier plated bullets? I might have to give AA a call.
