tmac - I would recommend staying away from Powerbelts as they do not expand well using 100gr of powder/pellets. The little green sabot boot that they use is insufficient to control gas blow by. If you reduce your load to 80 grains then you won't get this gassing and the Powerbelts will group and expand more effectively. 80 gr is still enough power to kill a deer inside 100 yards.
The SW on the other hand at 100gr of T7 powder/pellets expand much better beyond 100 yards. Chances are your friends dad shot that deer at a closer range.
Many Triumph users are getting excellent accuracy with 110 grains of T7 powder with 250 gr SW bullet. Some substitute a green Harvester Crushed Rib Sabot in place of the SW sabot for better accuracy. Using 2-50gr T7 pellets with the 250gr SW is also a great combo. Use the SW easy glide as they are a little easier to load. (yellow color sabot)
You have bought a quality mzl. Just make sure you clean between every shot to maximize accuracy. (you can PM me if you like and I have a specific process I use that I can share with you) A tight fitting bullet/sabot combo will always be more accurate than a bullet that is easier to load. I like to help new muzzleloaders as it can be very overwhelming process. Always ask as there are many good resources on this forum.
