That's where I was going with it, but I use the .452, 240 and 300 grain XTP non-mag with great success. I used to shoot the 240 grain ones with 80 grains of Pyrodex with my older inline. When I updated my gun a few years ago, I started shooting 120 grains of loose T7. All of a sudden, I'm not getting as many pass throughs, but lots of internal damage. I was finding the jacket shredded many times if any bone was hit. It was only after joining the Black Powder board here that I learned I was pushing them with too much powder. I then went back to shooting 80 grains and haven't looked back since. 80 grains will get you out as far as you need and with less kick.
