I just got a M1 Carbine in MMJ 5.7-22 Spitfire (30 Carbine necked down to .224)and I need some reloading data for it. Help me out if you can.
I have read several load books on 22 Hornet, K Hornet and 218 Bee. They all share the same powder/bullet with about 2 grains less powder. I plan to use these loads as a starting point and work loads form the 5.7.

Mickey, going through my old notes on the 5.7 Johnson, here's what I worked up about 15+ years ago: T/C Contender 10". rechambered from .22 Hornet,
cases-W-W, new; primer-R/P 7 1/2; powder-Hodgdon H4227-13.5gr; IMR4198-14gr; Norma N200-14.2gr. All loads with 50gr Sierra .224" These loads were safe in my Contender, but you may have to experiment a bit to insure reliable functioning in the carbine.. I did extrapolate charges from .218 Bee listings. Very accurate and fun to shoot. By the way, I trimmed the cases to 1.300" after fire forming. The chamber was cut with the thicker carbine brass in mind, so no reaming/turning was necessary..

While waiting for the gun to show up, I ordered dies. After finding NO BRASS, NO AMMO for the 5.7 or anything else, I knew that I would be using 30 Cal brass necked down. I had done that once over a weekend to make some 243 cases out of 308 and the rounds wouldn't chamber because the neck walls were too thick. I ordered a neck turning kit for 22 and 243 cases. After necking down and loading the cases, they miked BELOW max listed and chambered fine. SCORE! I guess the chamber was designed for necked down brass with no other steps. That eases up the brass supply issue.
Even though I have dies for about 40 calibers, I've never reloaded brass for the 30 Carbine. I am a brasshopper, so I had several hundred mixed cases in a can, so I am in business. It is a quirky looking round, and efficient according to my reading on it. It might not be much, but I'll bet you can kill a deer (carefully) with it. I wouldn't want to stop a round from it.
Thanks for the Norma data, I have the others plus one for 2400.
