Development of PP loads for the .44-77.

[Distant Thunder]

I just loaded up some .44-77 to test first chance I get.

520 grain BACO 431ADJ 1.425" OAL
.060 LDPE wad
80.0 Swiss 1 1/2 #040313
BACO brass (from .50-110)
Federal 210 LR
3.530" COAL

The bullets are seated in the case .160". I was little surprised 80 grains filled the case that high, but I believe that will work out well if I can get 82 to 85 grains to shoot well. That should give me 1300+ a few fps and that's a good place to be for Creedmoor.

Now to see how these shoot.
