Yes and no. Besides twist being a very important factor, as we all know it is, you also have to take into consideration the type and depth of rifling. And last, the powder charge. If you talk to many modern muzzleloader shooters they discuss their 100-120 grain loads. If you read the history books when these twists were first used, 40-80 grains was far more common.

The 1-32 is a nice twist but if you try to push powder hard in them, you might get some real strange results. Now when I shoot roundball I have been having good luck with my GPH shooting 50 grains. When I talked to Lyman about the rifle their load suggestions were 80 grains of powder with the conical bullets. A far cry from the 120 grain loads some shoot.

In a book I have about flintlock rifles by Don Davis.. he talks of his favorite deer load being 50 grains of powder and a patched roundball. His thinking was, the ball was very accurate, and penetrated to the vital organs where the ball would stay and expel all of its energy.

I am currently looking at a custom rifle. And the twist we are talking for a .54 roundball rifle is 1-66 to 1-72 twist. I am looking at a Rice and or a Colerain barrel with a Seiler lock. I want the best roundball shooter possible. I considered .58 caliber even a .62 but after a lot of discussion, we always seem to float back to the .54 as the best target and hunting caliber.

I always thought it would be interesting to get a White barrel in 1-24 twist, and make a flintlock out of that and shoot conical bullets out of it. What fun it would be to have a flintlock and shoot against friends but not tell them what the barrel really is....
