The Traditions Tracker .45 is a fairly inexpensive way to test out how the 1:20 will perform with heavy bullets. Performance is never guaranteed just like with any group of variables. There's more involved than simply the twist rate. But it would be fun to experiment without spending a lot of money just to find out.
It's the same with the 1:30, under certain conditions it may work better than expected due to certain variables. With muzzle loading, performance will always be hard to predict.
A little wobble may only result in a few inches of difference at practical hunting distances. Then there would need to be a baseline of accuracy established using another twist rate to compare the baseline to.
