Well there they are, my .44's
Left to right .44-77, .44-2-5/8's BN (.44-90 bn) .44-100 Rem ST. and the new addition the .44-75 Ballard.
I was able to make one sizing die for the Ballard but not the second one because the pilot bore was tapered to much that my smallest pilot the .437 would only go in 1.224". It tapered from .438" so I sent it back because I did not have a proper chucking reamer of the correct size..
Don I boxed the die up with some sized brass and it's on the way to WY. It should be in your mailbox by next Monday or Tuesday.
The brass plunks right into the .44-100 chamber so now all that is left is getting the rifle done and making a second die.
