.38-50 Hepburn

[Kurt]

What is the bore/groove diameter of the .38-55?

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.

More testing on the way. Hopefully Friday. 200 yards this time. They are just so much more dainty than what I am used to.

Those "dainty soldiers" sure look good.
I, too have some very similar soldiers loaded and waiting for something
above 20-25 degrees. Right now, looks like I will have to wait a while

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.

Kurt,
I agree, it would be nice to see Hemi noses on Accurate bullets.
I suppose a guy with a GOOD lathe/4 jaw chuck could dial mold blocks in
and use a profiled ball end mill to cut the flat nose into at least a Hemi.

Of course, it would be easier for a boring of the hemi nose while the blocks are still in the lathe at Accurate.

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.

[beltfed]

Kurt,
All that is most likely at Accurate.
And, Yes, for short range, such as Schuetzen- all at 200yds
historically, many bullets in common use had a flat meplat. ONe advantage being the FN bullets punch a more visible hole in the target
for spotting your holes.
BUT, nowadays, many Schuetzen shooters are using very sharp pointed bullets to good effect.
