.44-77 PP bullets.

Don.
The first bullet is for the 17 twist as in Jim's Krieger barrel which is a 0.438 bore and 0.446 groove : the body is 0.431 to patch to 0.437-0.438"
The base at 0.439 patches up to the FF case neck I.D. and 0.446 groove.

The second bullet is for 18, NOT 19 twist. and Matt's 44-100 Badger barrel is larger bore and groove at 0.440 bore and 0.449 groove.
so, for that barrel, we set the body at o.433 and the base band to 0.443 to patch to the FF case neck I.D. and groove.
Matt has some thicker paper-I think the 9# onion skin
from Baco that he wants to use.
