heavy weight for the little M1

[kenai kid]

Hi all ,I'm new to the sight and i'd like to congradulate the founders! I'm tryin to up the proformance of the m1 carbine and tryin to pin down a heavy weight slug that will feed and stabilize .Will the 311440 work?,might be to blunt to feed though, Nei has their #308-142GC #48 that looks promissing it just might work,before i dole the paper out i'd shur like some input.Better yet i'd like to purchase some of each or others that will work in the little carbine.
thanx KK.

I have used round nosed designs up to 125-130 gr, but that is the max that you can expect proper functioning in the carbine. In a handgun, it's a different story, very versatile with everything from 80gr up to 150's. The M1 carbine was designed for 100-110 gr bullets within a narrow range of pressure/velocity to feed and function properly, and there's not a whole lot that you can push that envelope without encountering failures to feed, stovepipes, etc. This is the limitation of all semi-autos, and the price that you have to pay to get proper functioning. Mine likes Sierra 125gr FNHP's, and shoots them accurately, but they don't expand at those velocities and they don't feed worth a **** - basically, it's a single shot with them. If you want to use bigger bullets in .30 caliber, you have to step up to .30-30, .30Rem, or 7.62X39 or wildcat .30/223 or .308X1.5". The M1 carbine just isn't designed to handle the heavier bullets you are proposing.

I've been trying the 311440 (Lee 6-cav GB) in mine. I haven't encountered any functioning problems as long as I had ENOUGH powder in the load. I am using AA1680 and worked up from a minimal charge. Feeding......well, that's another story!! The little beggars won't even come out of a GI mag unless you take a Dremel tool and open up the front a wee bit. I'm going to try seating them a bit deeper next, but now that we have all this white crap on the ground it may be a while. I hate digging my brass out of this $heet!! BTW- I had them running 1500+ fps with no signs of straining anything.

Hello,
Bullet nose shape is the key to functioning in the GI Carbine.The fine Lyman3118 115 grain bullet shot very well,but was essentially a single shot venture.The pointed Lyman311359 115 grain bullet with GC(cast hard)works great and shoots great
A custom 120 grain bullet with a moderate meplat(same as Lyman311041)functions very well and shoots OK.
Almost any round or pointy bullet loaded to a maxOAL of 1.68 will probably function in the gun. I never experimented with heavier bullets because there is not enough space left for enough powder to interest me.

As i've mentioned before, the 311359 (120 gr in my alloy) works VERY well in the G.I. .30 Carbine. My load is 12 or 13 gr of H 4227 and WSR primers. Flawless functioning and "minute of Carbine" accuracy. No leading as a bonus.:wink:

Others on the forum have had very good results loading the SKS Carbine (7.62x39) with heavier boolits, but I don't remember much, if indeed ANY, data about .30 Carbine and heavy boolits.

Thanx guys for the input,Is that 311359 design still avalible, I,d like to give it a try sound like its a goodun.I'm still ponderin on weather i should purchace the NEI mold i'm really likin the looks and it just might feed ok, if not it'll work in my 300 sav. This project is to be used as an emergency survival gun in my partners supercub. and he's wantin some heavyer loads to be used on larger game along with the standard foder for the small stuff.

....................kenai kid, welcome to the board. The Lyman 311410 @ about 130grs will work in the Carbine. I had an Iver Johnson made 30 M1 and it shot well in it.

Kenai,
That Lyman 311359 GC bullet is lighter in the Carbine because I cast it much harder to operate in the semi-auto.
That bullet is quite popular in larger calibers,and,I think,still available.I have'nt shot it in my 300Savage but it does very well in my '06 and Krag.

Kenai Kid,
I've been using the Lyman 311410 (130 gr. FB RN) in my M1 carbine with out any problems. the 30 carbine has a 1-20 twist so might not stabilize really heavy bullets. Probably need to check Greenhill's formula or similar to determine max bullet length for 1-20 twist and 1500 fps or so. The 311410 is cheap and easy. cheap as there's no gas check, easy because you don't have to mess with gas checks. Makes for a nice "plinker". I've been using water quenched WW alloy and LBT blue lube. I've decided to see how many CBs I can run though my carbine before something becomes gummed up enough to not function. About 800 rounds so far and no problems, yet. No leading either. Someone told me (and I need to verify first) that the throat on the M1 carbine chamber is very generous (0.313 or more). If that's true (and again I need to verify) then I'll be just lubing these CBs and seating and not sizing (if the round so loaded will still chamber). I wish I could get the 311410 in a 6X or more cavity mould. The Lyman 2 cavity works fine but I can shoot them lots faster than cast them, if you know what I mean. Good luck and keep us posted on how your project turns out.
best regards,
brian

Hey Brian,
I was hearing about some guy on the "Amback" forums on M1 carbine saying he shot over 1800 rds. thru his & it was still functioning. He was using the Lee 120gr. I have the Lee 130 gr. in addition to that 120 gr. and it shoots great but just not being real practical doing em one at a time and then shooting 10 rds in 1 minute. Would be nice to have a six banger like you say. I use good ol Liquid Alox. Maybe with that plain base, could try some stiffer stuff in my lubrisizer so as to not pollute the base of the bullet with lube. Just primed up 1000 empty cases...Now to finish the job.

KRagman...When sizing the 3118, use a Lyman #311 top punch. This "bumps" the edges of the meplat a little and they'll feed just fine./beagle

Beagle,
Thanks,I never thought to try that.But I no longer have the mold.My particular Carbine shoots the Hornady SJ 100 gr bullet very well and it is the cheapet bullet that I can buy.

Well,Were feeling rich and took a gamble and ordered up one of the NEI#48 molds and the lyman 311410 I'll keep you all informed on the out come of my trials and tribulations it'll be fun.
Later KK.

I'll be interested in your results with the 311410. That is one mould I have not tried in either my G.I. Carbine, or my "new to me" Ruger BH in .30 Carbine.

Good luck, and keep us posted!:lovebooli
