Development of PP loads for the .44-77.

[Kurt]

Jim, This rifle has always shot very good. I designed the reamer only for a PP bullet and the outside case mouth is only .462" fired.
Lee has stopped making custom dies for the 7/8X14 threads and I don'r have one for the DD. I have a .438" for the bore diameter.
This DD would smile for a breach seated bullet and I will make a case for this DD for my breach seating tool.
The bullet patched with 55Y measures .447" and it's a very tight fit in the case that has .009" thick walls and some of my Starline cases run 10K +-. The 55Y paper thickness is as low as .0013 to .0016" depending where I put the mic on the sheet.
Right now the only way I can make this bullet work if flaring the case mouth seating the bullet and run then through a .44-100 taper crimp die I have. It's not the best and I figured I would have more vertical than I had today.
The Shiloh Hartford .44-77 you shot the DD is perfect using .0018" paper but the Farmer .44-77 has a more generous throat that I have to use .002" paper for a proper fit in the case without having to size the neck down and the front of the base fits right in the lead taper of the chamber.. The whole profile of the patched bullet fits the throat taper and bore riding shank. I think that is why the different loads don't show much difference on the paper. But Rapids will tell the final outcome at 600 yards if they hold up. If they will hold at 600 then the 1K has a good chance.
I have or has 400 bullets cast so I have enough for more shooting before Rapids with out having to heat up the lead pot again.
