I shoot the 295 grain Aerotip Power Belt in my TC Encore. I use 2 pyrodex pellets and a 209 primer. When I first starting shooting the bullets, I tried them with 150 grains of power. The accuracy wasn't that great. When I dropped down to 100 grains, I was getting 1.5" groups at 100 yards.

I have shot whitetails and a caribou with this setup. The Woodland Caribou was 95 yards away and the bullet did it's job. There was no passthrough, but I didn't need a blood trail as I watched the stag buckle and go down. It weighed 300 lbs so it was a fairly large animal. Although caribou seem to be easier to put down than whitetails (and I'm sure elk) in my experience.

I will continue to use Power Belts as I have been happy with them. In regards to sabot bullets, I have had good luck with the Knight Red Hots.
