Also, it appears the TC guns recommend the Sabots, but I have always liked the Powerbelts. Anybody have any experience with the TC guns and Powerbelts?
Sorry this got so far off from the original question.
Most get by with Powerbelts in their TC, Saxman is one of them who likes them in his Encore and hopefully will be using the 270g platinum IF they shoot well. So far it doesnt look like TC's are liking the new Platinums. Its a throw a coin up in the air and hope the rifle you bought will shoot powerbelts or any conical with acceptable accuracy.
Im from Colorado and we're restricted to open sights, conicals and loose powder "No smokeless" and Powerbelts for me are always easy to find, well stocked even at small town stores and they come in a big variety of bullet weights. 175- 500+ grains. Been using them since late 2001, Maybe early 2002, memory is a bit fuzzy on that. But my first real muzzleloader "first was a cva blazer made in 1987" was a TC .50 Renegade and i used to shoot the 295 AT with 90g Pyrodex RS and that sucker would just shoot them all day long. Keep in mind the TC conical issue is mainly with their inlines and the QLA set up. I had a TC Hawken a little while back that shot the same load only with 80g pyrodex select. The only rifle i've owned that i havent shot a Powerbelt through is my .54 lyman great plains rifles
and my .54 smoothbore.
Knight is another rifle that seems to shy away from the Powerbelt bullet due to the difference in bore size. Corey on the other hand seems to be getting very good accuracy out of his older model knight.
So to cut things short, the only way to know if the rifle will shoot the bullet you want to use, is to buy the bullet, a couple different powders, a few different primers and get to the range.
Besides powerbelts, Patched round balls are the only other bullets i use to hunt with.
