I’m guessing I’m asking for too much here
No you’re not, and that’s the great thing about the 45 Colt. For cowboy I use a Penn 200 GR RNFPBB which is a great round in lever actions and will never jam. He has the same bullet in 255 GR. The nice thing about the 200 is that it will also work well in the 45ACP. And there is also a 152 GR bullets which I have never tried. Don’t know how it would work in the two guns you’re talking about but this is just one manufacture.
My Marlin will not work well with semi wad cutters. More than once it’s locked up to the point I had to dissemble to clear the round. I wish I knew the secret of getting them to work in mine.
