The Great Plains Hunter model features a fast, 1 in 32" shallow groove rifled barrel. It's ideal for shooting the many types of modern projectiles available to today's black powder hunter, such as heavier conical bullets and sabots. The Great Plains Hunter has all of the high quality features of our Classic Great Plains rifle. It is also pre-drilled and tapped for the optional 57 GPR receiver sight for the Great Plains rifle

I'd try conicals or powerbelts before any sabots in that twist and gun..... :twocents:
Why? ??? It's made for shooting sabots.

I'm not a fan of sabots at all.... Not that they aren't accurate or dependable.... I'm just a hater..... :dunno:

1-72 twist, deep cut rifling, patched ball.
1-48 and a little shallower groove, a compromise for conical and patched round ball. Much of the earlier T.C. guns like this.
1-32 and faster is conical.
Exceptions are like what I have on my .36 cal. flintlock. A 42 inch barrel starting at 1-72 and accelerating to 1-36, moderately deep cut. Extremely accurate patched roundball.
There are other factors such as straightness of barrel, smoothness of rifling, consistency in hole diameter. Diameter near the end of barrel etc. All the stuff said on this thread is not going to determine how the barrel shoots. You are going to have to try different projectiles, Types of powder, powder charges and even caps to get the optimum accuracy.

There is more than rate of twist in determining how a rifle barrel shoots. The depth of the grooves is important. Patched round ball take a deep groove, or the patch can not grip the rifling, to deep the pressure blows by. Lead conicals take a shallow groove, or the pressure blows by. I do not know about sabots. A general rule of thumb is:
1-72 twist, deep cut rifling, patched ball.
1-48 and a little shallower groove, a compromise for conical and patched round ball. Much of the earlier T.C. guns like this.
1-32 and faster is conical.

The 1:32 twist is likely to shoot lighter bullets a little better than a 1:28 twist barrel would shoot lighter bullets........that is what I suspect the difference would be between the 1:32 and 1:28 barrels. If you like lighter bullets, the 1:32 may be a better choice than 1:28.........
