What is the rate of twist? The .50 caliber is 1-48 I believe and the .54 is 1-66. So I really do not see them shooting minnie ball. Although the .54 might have a chance. Personally I would shoot the roundball and be happy with that. I cast minnie in .50 and .54 and have yet to find a rifle that shoot them (in my collection) satisfactory to hunting accuracy that I demand.
.54 34 5/8 1-65 twist That would make it a roundball barrel.
Rifling may be too deep to properly seal a conical,that rate ot twist is slow to stableize a long conical
May work with a shorter conical around 300 gr may have to experement with & without over powder wads.
With a shorter conical may shoot good , bad or ugly or just maybe realy good.
with a short conical you would still need a heavier load , the faster the bullet is going the faster it will spin, the spin would be needed for stability.
I understand that you are looking for someone who has tried it , so far nothing.
Now that the rate of twist has been established someone who has tried something on a like or near like barrel may have some report to how it worked instead of just theory.
Your english is no problem,sometimes you need a little more detail, untill I saw Pedersoli I had no idea just what you had, one word can make a huge diference.
Add to your information location Croatia, it will appear on all of your post.
Welcome to the forum. Its a pleasure to have you here. As for your rifle... because of the twist, they just do not shoot conical bullets well, in my experience with them. I have several roundball rifles and they have similar twists. I purchased them because they were roundball rifles.
Never under estimate the killing power of a .54 caliber roundball. They will drop large game animals a lot better then you might think. Also with the slower twist you have, you can push the ball a little harder and it will not skip the rifling. So even with a heavy powder charge for the larger game animals, it will be accurate and be an excellent hunting weapon.
