I have a T/C Encore .50 muzzleloader, and I'm a relative newby to muzzleloaders. I've used it twice successfully, but I'm looking to try something different, not because of poor performance, but just to try something different. I currently use a Hornady .45 250 grain bullet with a sabot, but I have seen someplace that you can use a .40 bullet inside of 2 nested sabots (the first sabot for .45 caliber rifles inside a second sabot for .50 cal rifles).

My questions are following:
1. Is this indeed feasible?
2. Is it dangerous?
3. Will it increase velocity and flatten trajectory for a 200 yd shot (.40-200 grains vs .45-250 grains, both with 3 pellets)?
4. Does it degrade accuracy (using 2 sabots instead of 1)?

Thanks for the education and assistance,
