Loading .54 cal GPR

[M40A1]

What is everyone's favorite round ball diameter and patch material for loading .54? What about your favorite lead bullets? I am ordering a Lyman Great Plains rifle and need some starting points. I have a good supply of Goex 2F already. Eventually I will buy a second barrel with a 32" twist for this rifle, but plan on using the factory barrel for now.

I used to have a LH flint Lyman GPR in .54. I used .530 roundballs with pillow ticking patches and Bore Butter lube. Try 70 grains of 2Fg to start and work up if necessary.

Frodo gave you a good starting point. If a hunting load is what you want, bore butter is pretty good. It can add to fouling and you might want to wipe in between shots or every other shot.

If just punching paper (nice big holes) try a 50/50 mix of Murphy's Oil Soap and water for a patch lube. Also, pillow ticking is available from your local fabric store and much cheaper to buy a yard and gut your own which watching TV at night than to buy pre-cut.
