And you can call them bullets here, not seeds
This isn't Fascist book, and anything, even gun pics are fine

I gotta get these loaded up for hunting and was wondering what's everyone's favorite powders and amounts? I have 405gr cast seeds for the 45-70, and 200gr jaketed bt seeds for the 300. I was going with imr- 4198 for the 45-70 and imr-4350 for the 300.
