Home Forums Hunting & Shooting Muzzleloaders 405 Grain Remington JSP Muzzleloader Use?

I have a question for some of you muzzleloader guys. I have a bunch of the factory Remington 405 grain JSP bullets for my 45-70, and was wondering about using them in my 50 caliber Apex this year. I found where MMP makes a 50 cal sabot for .458 bullets. Anybody ever try this combination in a muzzleloader? What kind of ballistics? How did they shoot/perform?

Thanks, Troy
