The Lyman Trade Rifle has a 1-48 twist which will allow it to shoot roundball and some conicals very well. The Great Plain Hunter has a 1-32 twist and is meant for shooting conicals. The Great Plains Rifle has a 1-60 twist and will shoot strictly roundball for the most part although some people shoot ball-et and even some minnies from them. With what kind of results I do not know.

The .54 caliber IMO is far superior in everything to the .50 caliber in the Traditional Rifle sense of the considerations. If your shooting roundball, there is a 33% increase in weight over the .50 caliber which means more long distance thump. Also the .54 caliber while a disappearing breed in the modern inline rifles is still strong and easy to find projectiles on line in the traditional world. When I look for a traditional rifle, I look for the largest caliber I can find. The twist is then the second thing I look for in realtion to what I want to do with the rifle.

The Lyman Peep sight mentioned is all set to go on the Trade Rifle.
