.44-77 PP bullets.

Jim, Yes, your math appears to be good. With the 55Y you may very well be able to shoot
Matt's bullet (dimensions) in the .438 bore barrel.
And as you said, you could always slightly size the patched base band if necessary.
I am sure you would mfg and use a very polished sizing die so as to not tear that
"tender, thin " 55Y paper. I had tried sizing some 38 cal gg bullets that I had patched
with 55Y in a Lyman H&I die. Paper ripped on the lube holes even tho I had polished the bore.

At 1.39" long, Matt's bullet it should be very stabile from your 17" twist barrel.
As said before, I had dimensioned the bullet for Matt's larger bore barrel
and also, he wanted to use some 9# paper they have on hand that adds about 0.0075 or so.
Hopefully , Matt will bring along to Rapids on Sat, a few bullets if he has had a chance to cast some. He said he is very
busy at work, even worked last Sat.
I am looking at shooting some with my 38-50 at 300yds and possibly at 600 if there is time after
the Mini Palma Setup is torn down and range re-opening....It is supposed to end at 1pm.
I am hoping to try my Caldwell Target Cam, too.
Matt has said he and a friend are coming up for the Min Palma and I also invited him
to "bring a SmokePole" if he wants to shoot a bit.. Perhaps the 44-100?????
