The Hornady 325 gr, .45-70 works well with me. Managed to get the yard cut this weekend, and sorry guys, no Cape Buffs there. I thought for sure I saw them. I think, (HELP TIM) you can shoot any standard .45-70 load in your Handi, and won't hurt it a bit. I think with the +Ps, the only factor is your shoulder.
