I am still digesting material from page 1 & 2. So my question goes back to there. There have been references to AM molds 165A, 188?, 195X, NOE 30XCB, Mihec 30 SIL.
Just as a broad statement are the molds that get the most engraving by the lands designed more for the bolt/single shot guns. And the molds that produce bullets that have minimal to no engraving when they are chambered are more for the autoloaders.
Sorry for the sidetrack! Kevin

okay I can see what's up here.
I got the crooked can't get below 1-1/2"s no matter what chamber too.
pisses me off I wanted one of those rifles for years and years, and I get remington'd.
the throat is very, similar to a saami 308 throat only at 323x314
anyway that 323 out front there is probably what is killing you.
I'm using a mold for the 32 Winchester with a nose diameter that's more inline with 314.
this has an undersized nose but would be a closer fit to what the throat is like.

no problem Kevin.
the semi-auto's of course pose their own set of problems.
but once again the throat is the determining factor
in MY AR-15's the rcbs 055s is set back far enough to not even come close to the rifling.
the ED harris 155gr design I think NOE is cutting now is also set up for the SKS type rifles it is meant to slide into place but with minimal space between the bullet and the barrel.
they work on the same principal as the xcb bullet does.
a bit harder alloy and a jump to the rifling is the norm.

What sidetrack? This is just what we're talking about.
To your question, you could group those moulds into those two "boxes", but it isn't inclusive. Like me having the best luck in my .308 bolt rifle using the MP 30 Sil, even though i can shoot the exact same ammo in my M1A and the bullet doesn't touch the throat in either of them until fired, cartridge just falls in to the shoulder *clink* in both if I just drop one in the chamber. I need to re-work that load because the spindle valve doesn't appreciate the buffer very much.

see what you got first.
I really doubt my rifle is better than the 1-1/2"s I have wrung from it with both jacketed and cast.
I have 100 round groups showing that is all it can do.
it is consistent but that's all it gives.
keep things like that in perspective.
the sized down nose could be all you need to fix what you have.

Run, how is the throat in that 8mm? Is it like a military and about 1" long? When I had Shaw build my heavy barrel 8x57 I had to seat every bullet maker bullets almost 0.015" deeper than all the books called for. While it made for decreased powder cap. it also held the speed back a little. After I had about 1K rounds of bracketed through it and the throat settled in I picked up almost 100fps. 200hpbt Sierra 2550fps.

it's short.
the 165-A would actually be a decent design for it with the proper diameters.
if the chamber was cut straight it would be a damn good rifle.
I was shooting 150's out of it matching my 0-6 for speed without even trying.
it's short enough I picked up a 140gr loverign type tumble lube design for plinking with it and seat the base like a normal bullet otherwise I bump the rifling.
