I am figuring onusing a .45-70 and necking it to .410" with a sharpish shoulder to keep as case capacity as I can. I am thinking it should push a 400 grainer to 2100fps or so, which is right neck and neck with the Hornady loads for the 450/400 3in.
From what I gather the bullets Hornady is using in the 450/400 are also sized .410". So I could use those for heavy bullets, but also could run any of the bullets available for the .41 Rem Mag. Which gives the spectrum from sierras 170 JHP all the way to LBT's hard cast 250 and 265 grainers.
All packed in a trim little levergun......
