With a 1:32 you should be able to shoot just about everything 1:48 is the twist on a lot of the older guns and thats good for round balls and conicals, then most the newer inlines are 1:28 for sabots and powerbelts etc I would try a few combos and see what it likes best :IBCOOL: |

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. 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. |
