My Son and I shoot 35 grs of IMR3031 under a 405 gr hardcast LRNFP bullet. 1250 to 1350 fps, I have been told, don`t have a crony. In all of our 45-70`s very comfortable load to shoot in any thing we have. We Hunt, Plink, and Cowboy Shoot with this load. And we have never shot a Pig or a Deer that we did not get full penatration either side to side or end to end with this load. I have quit shooting the shoulder bumpers, I turned 71 this year and just to darn old to shoot them any more, and really never needed to, where we hunt.
