I looked this morning and I have 4 boxes of 350 gr .50 TC Maxi hunters bullets. These seam to load fairly easy in her gun but I have not shot them. Might try these tomorrow. Need to figure out how much powder to start with. I am more concerned with ease of loading than with recoil. She shoots a 20 gauge 3” slug with no problem.
I never had a lot of luck with Maxi hunters, but when I would shoot them I never pushed them hard. 70 grains of powder is normally a good starting point with them. If they group well with that, it is all the load you would need for deer. And if she can shoot a 20 gauge 3" she can shoot anything she wants in a muzzleloader...
