Reloading for my M1 carbine do I need to use a crimp die or a taper crimp die for this rifle. I crimp all my reloads for my semiautos. AR,AK M1,SKS. thank you.

Head spacing on the mouth of the case, I'd think taper is the correct answer.
But I was the only boy with 3 sisters, what could I possibly know?
Taper crimp!
If you are going to make a hole in something. MAKE IT A BIG ONE!
If you happen to have a Lee 120gr RNGC give that a try. Our carbines well shoot those.

Never had a function problem with the old fashioned crimp. With straight and semi straight wall semi-auto cases it is important to have no significant flare at the case neck for consistent feeding.
I never have had any problems with mine relative to primer ignition and using a crimp. A taper crimp would be better for cast bullets I think.
One can see that this case has a slight amount of tapper from .356 to .336. for a pristine new factory shell.

I don't think I've ever seen nor even HEARD OF a roll-crimp die for .30 Carbine. It's been MY impression that all reloading dies for it were taper-crimp, only. I guess one can get most anything wanted on a custom basis.

Yes for a taper crimp
Larry...how do those beautiful LSWC HP's function and what sort of accuracy are you getting? Sizing to 0.310" has worked in several '03 Springfields for me...is that good for M1 carbines as well?
I've had a pair of carbines since the early 70's that have always been fed FMJ's...accuracy runs to ~3" or so a 100 yds. I've got Lyman's 311259gc as well as a cpl 0.314" .32 cal. molds but have always hesitated fearing lead infestation in and around my gas port/piston. What say you? Rod

Last time I shot them a 15 round mag went into 2 1/4" at 100 yards from my shooter scoped M1 Carbine. I size them at .309 for the M1 carbines. Functioning is 100% but I've polished the feed ramps on my shooter. Before that one occasionally would hang up on the feed raamp. Never had the problem in any M1/M2 with the 311359 cast bullet.

I shot thousands of 311359s through numerous M1/M2 carbines and had problems with only one. That was with an M2 Carbine that had a burr on the gas port which led to leading past it. As to build up of lead/fouling in the gas cylinder, it's never been a problem. Even with M2s fired full auto.

Larry, Many thanks for the response...I'll give it a try. BTW, using that 311359gc in my two Krags was a revelation. Sized 0.310", they didn't lead whatsoever, and accuracy with the issue sights (and my eyes) was superb. 2" or less at 50 yds, if I spent some time inspecting them. Annealing the GC's helped as well, reducing 50 yd groups by 1/2". Oddly enough, that same bullet didn't perk as well in my '03s, which really liked 311291gc at 0.310". All of the above were wheel weigh alloy with enough tin to help fill out and air cooled. Best regards, Rod and thanx again.
