Development of PP loads for the .44-77.

Jim,

A just finished casting 75 with my L/T/A alloy and they dropped from the mould right on the button the specs say. I dug the new mic out and took some measurements.
The bore section is .43112"
The base is .440037" close enough.......
Length is 1.44001"
And it's round with no runout.
The weight is 5055 grains.
It falls right out of the mould just opening the blocks. Great work!!!

I checked theater from the base to the shank and it matches my funnel throat.

I been working with the CPA .44-100 straight this week and I have a hard time keeping the bullets on the 2x3' paper learning how the use the new scope. Some bullets I shot I can cover with a quarter at 200 and some of the other 3 shot groups barely stay on the paper.
This barrel is a 16 twist I had made in Oregon that had very drop grooves that I worked on getting closer to the cartridge rifle groove depth and I have it working but it's very selective the bullets it shoots.
But I will put the 100 aside and get the .44-77 and see what this new bullet can do.
