The Hornady pa conical cayugad mentioned is very close to the ball-et and should shoot the same. hornady makes the great Plains bullet in a HB HP that is the best conical I have ever shot out of my Lyman. The 50 cal is 385 gr I think. A 1 in 48 twist will shoot it fine. It is twice as expensive as a ball-et or PA conical but worth it.. I pay $6.50 for a box of 15 here. But when you hit a deer with it they don 't go anywhere.(the deer that is) They are heavy enough to maintain quite a bit of energy at 100 yards or less.I am using it exclusively in my 54 cal this season. That's the fun of trying different combinations. I would stick with 4f for the pan and 3f for the load. 3f produces a little more pressure and better burn rate.Just reduce the load over 2f by about 10%. ( my opinion). Good luck and have fun
