Hey guys, I bought a new 45-70 1871 Buffalo Classic w/32" barrel. I can't find much as to the loads and pressures for this rifle. I bought the Lee 405 grain hollow base bullet. Cast about a 100 or so the other day. Sized them down to .459. I bought some IMR-3031. Loaded some up w/42 grains and shot ok. I feel the loads were pertty lite my self. I was hoping some of you could throw some load info my way. Also will be loading these with black powder over time. Thanks all. Bob
