The deep curl has a great reputation for performance on game. I just ordered a few hundred this week as my current supply is very low.
Here's my load:
70 grains by weight of Blackhorn 209, Winchester W209 primer, Harvester EZ Load Black Sabot (non-crush rib)
I don't know how the typical CVA bore compares to my TC, but lots of CVA shooters here who can chime in on where you may want to start for sabots.
I got a bunch of help from the members of this forum getting the muzzleloader to shoot.
The best advice I've gotten so far is to avoid muzzleloader specific primers with Blackhorn 209, keep the flash channel of your breech plug cleaned out with a drill bit (hard carbon fouling builds up), seat the bullet on the powder with consistent pressure, and enjoy the process!
