I just purchased a T/C Encore in .50 cal muzzleloader and was wondering what type of results have some of you had it and what loads you have found work best. Thanks

You have to just try as many different combinations as you can until you are satisfied with the accuracy.
My first encore barrel loved 250grain PTX sabots over 2 pellets of pyrodex. Three shots touching at 100 yards. However, with the 250 grain Barnes I couldn't even get in a three inch group with any type of powder. Long story, but that barreled was ruined so I got a second barrel.
The second barrel likes 250 grains Barnes bullets with either 2/3 pellets or anything in between.
I am currently working on a load of 300 grain Hornady XTP with 2 pellets for a hog hunt. They group about 1 inch. I was about to switch to loose powder to see if I could close it up some more but my scope went up on me.
Neither barrel liked 180 grain sabots. I have also read that a lot of people have had good luck with powerbelts. Hope this gives you some ideas and helps out. Good luck.

Might want to take a look at PRBullet.com 's Dead Centers. For a sabot shooter, they might be the cat's meow. I would try some of the mid to heavier ones and start at about 80 grains of loose T7 FFg. Damp/dry swab after each shot.

Betcha like 'em.

The new sst bullets are out made by hornady,I have tried the 250 and 200,haven't seen the 300 yet.T/C has the same thing out too,I would check them and the pr bullets out.
