.44-77 PP bullets.

[beltfed]

Jim,
I expect, the bullet for Matt's 44-100-18twist is going to be too large on the diameters for
your 44-77 barrel/chamber.
His Hepburn had been rebarrelled with a Badger Barrel in the very early days of Lodi matches when run by Ernie.
It may even have been cut rifled before Ernie got into the "big time" and went to broaching barrels.
The bore and groove diameters are larger than (most?) current barrels. the groove dia
as measured by Matt's Cerrosafe chamber cast is at about 0.4496-0.4498 ( minus less than 0.001 for older Cerrosafe expansion)
The chamber also has about a 0.125" freebore at about 0.451" dia.
In fact Dave Gullo, upon looking at my drg dimensions said the bullet was too big diameter for .44s .
But, I think we got it right. Matt told me after receiving the mold that fit of the bullet that came with it is good for this rifle.
Baco has said they can adjust diameters on a cataloged design, but other adjustments pretty much
require a separate new mold design.
