I will be starting to load for a .458 Lott and would like to load some reduced-velocity loads for practice, but stouter than what Trail Boss would provide. Hornady helps me with a 500gr bullet and 4064, and Midway thoughtfully had a sale on blem .458 500gr softpoints.

I have a good supply of the Remington 405gr bullet that I'd loaded for a .45-70 lever gun. I don't think this bullet is constructed for the velocities the Lott could potentially generate, but I'd love to find a load for these that would deliver about 1600-1800 fps in the Lott for practice. I can't find any suggestions on the internet. Might any of you have a safe load you could recommend? Thanks!

Hi England,

I have no experience with the 458, but have used 400 gr cast bullets in my 450/400 using Trailboss. I'm getting about 1650 fps and excellent accuracy.

You would probably be better off putting this post in the Big Bores forum.
