RE: .38-50 Hepburn
What is the bore/groove diameter of the .38-55?

RE: .38-50 Hepburn
Kurt,
.368/.375
Arnie,
I’ve had considerable barrel leading with my grease groove bullet. I had a pretty good idea what was causing it and the bore scope confirmed it.
However it’s been behaving quite well with the PP bullet I’ve been using lately.
I should receive the new mould for your bullet design in the next two to three weeks. I won’t make any decisions until then.
Jim

Arnie,
I received the new DD 38 mould from Accurate.
I’ve cast and loaded a few bullets but it’s been too bloody cold here to do any productive load testing.

Jim, What is the catalog number of that bullet?
I like Tom's work but I wish that he would start making an elliptical nose.

RE: .38-50 Hepburn
Arnie,
He lists a meplat of .18" that could be reshaped with a ball mill, but he will only cut a mould 1.375" with the blocks he uses. I have a couple brass .44's and .308" and they are large enough for a 1.4.
I would presume that he is most likely cutting these moulds using a CNC because of the precision he cuts a multi cavity mould. Hi probably does not have the tooling of the program to cut the Hemp nose. Or one could do it even reshaping a boring bar.
For short range/midrange a meplat of .18" is not a problem.
