Did a search for .40-65 and didn't turn up anything. I shoot a Remington RB .40-65 and was wondering if anyone shoots a .40-65 in a Marlin lever action.

I have two vintage Marlin Model 1895's in .40-65 calibre within 500 serial numbers of each other. One has a 28 inch barrel. Only about 5000 were made. They weren't too popular, presumably because of their weight (although the Winchester Model 1886 is just as weighty), and seemed to sit in Factory inventory for a long time. My rifles were made in 1895. Both group very well when I use a 300 grain FN cast bullet of 20:1/ Pb: Sn alloy. The original specs called for a 265 grain F.N. bullet over black powder, but I shoot I.M.R. 4198 to blackpowder velocities ( 1300 f.p.s) and that uses up 21 grains of powder. It's important to slug the barrel to determine the groove diameter of your rifle and to shoot a bullet one to two thousandths of an inch greater than this measurement. These old original blackpowder rifles are almost always overbore for a .401" bullet because blackpowder results in good obturation of your soft cast lead bullet thereby sealing the bore from hot blow-by gases which heavily lead the barrel. Smokeless powder doesn't achieve that end to the same extent so your bullets must be loaded and fired overbore size. Sometimes it becomes impossible to chamber these overbore bullets because they stick at the chamber throat. Then it becomes a matter of choosing to use blackpowder or opening up the chamber throat a hair to accept your new bullet diameter. I chose to do the latter with both my rifles as I've had my fill of blackpowder and I'm not going back there. Both my rifles slug to .409" and my 300 grain bullet drops from my mould at .410" and I fire these unsized to obtain 4" groups at about 80 yards. If I don't follow this procedure and shoot underbore sized bullets with smokeless powder a lot of bullets don't make it to the paper at all while the ones that do tumble and enter the target sideways, and in groups of about a foot. Hope this helps. It's a wonderfully accurate old calibre with far less recoil that the .45-70, from which cases may be made in .40-65 by necking them down.Did a search for .40-65 and didn't turn up anything.
