Development of PP loads for the .44-77.

[Distant Thunder]

There is no doubt that BACO .44-77 brass that I have, I just bought it in June, is tight in the neck ID on the fireformed cases. A bullet sized to .4465" will not push into the case. That same bullet will easily slide into a fireformed JBA case. I will check the BACO brass with a gauge pin as soon as I can.

After fireforming the length is between 2.250" and 2.246", that's a good length. The OD measures pretty much the same as the JBA, .4675" at the mouth tapering to .469" at the shoulder. Those dimensions are of course controlled by the chamber and would be expected to be the same.

The BACO stuff looks really good except the tight necks and that I can fix.
