Reloading the .30 carbine

[rondog]

And I have tested and used those.


Attachment 156564.

In my opinion, the bullet on the left was drilled WAY too deep. I wouldn't go anywhere close to that big. My idea is to only drill the taper a little larger than the pilot hole, just enough to make it look like a regular factory made hollow point. More like the bullet in the center, but with just a little bevel to it, not a lot.

That was done only to show on another thread just how large a HP one could make in a 45 ACP using the Forster tool to initially center the HP and then how far it could be opened up with the center drill. It is way too large and too deep for my use also. However, if one wanted max expansion and minimal penetration that certainly would do it

As far as the 30 Carbine goes the 1/8" HP with the Forster tool alone as in the other picture does just fine.

Looks like the #4 center drill would approximate the Forster with a little bit of a flair. I believe it will do equally as well.

According to TM 9-1305-200 the accuracy requirement for U.S. Ball 30 Carbine ammunition is “the mean radii of all targets (10 shots) at100 yards is not greater than 1.5”. Testing was done “from an accuracy weapon mounted in a test fixture”(usually a sample production weapon in a machine rest).Thus the worse case acceptable accuracy isabout 3.5 moa at 100 yards. Was each M1Carbine accuracy tested? No, they were proofed and function tested only. That’s the same with all military standard issue weapons since pre WWII. I believe the last accuracy tested before acceptance rifles we used were M1903s made at Springfield Arsenal.

I’ve shot a lot of M1/M2 Carbines over the years and found most of them, if in good condition and properly assembled in the stock, would shoot 4 – 5 moa with U.S. Ball ammunition. With good hand loads using a quality Hornady, Speer or Sierra bullets they will shoot a lot better. Bed one properly and they will do even better. Shown is a 10 shot group with the Hornady 90 gr XTP at 100 yards from my shooter M1 Carbine previously shown.

Thanks for the TM been looking for that. Good to see the mean average is well below the carbine test target requirements.

Thanks everyone for the great info on casting for the carbine...

Anyone have to ever clean a gas port?

As to why carbines don't seem that accurate, I find the guns themselves aren't that easy to shoot well. A really short sight radius, and an eight pound trigger on a five pound gun aren't conducive to tack driving accuracy. It has always been difficult for me to shoot them consistently well. Some days they shoot surprisingly well, the next, shotgun patterns! I do agree with a previous poster, even on a bad day an issue 1911 would have been worse at the same range!!

Anyone PC this boolit and run over some H110, 2400 or AA9?

I never could get a decent shooting C.B. load for either of my GI M1 Carbs .
When the Speer 100gr Plinker bullets were cheap and plentiful I shot them by the thousands (first loads I ever put out on my new Dillon 450 in 1980) at all manner of varmints .
Have killed several whitetail & muleys with the 110gr jsp . I would nor recommend it for that purpose but it will get the job done imoh .
