Loads for .30 M-1 Carbine Rifle:

(Note: These are maximum loads, you should use 3-5% less to start.) I was advised by a fellow shooter on the web, that backing off any more than 3% would not allow the M-1 Carbine to function properly. With any auto, the loads will be trickier. You certainly want to measure your powder carefully and check the loads to make sure you have the correct bullet weight, type and powder before shooting.
(See note on Powders below or read all about various Powders.)
Bullets are .308″ and .3085″ diameter. Due to different barrel lengths, type of bullet, seating depth, primer type and other factors, you may not get near the FPS charted. It is just a guide and the reason you should start under these charges and work up.

Discussion: For owners of M-1 Carbines, it’s a lot of fun to fire away with this little semi-auto. Loads need to be fairly consistent to make the action work properly. Ruger had a cylinder for one of their single action, six-shooters that would use the .30 M-1, so you could use the same cartridge in your rifle and handgun. As I remember, that pistol would use several types of .30 cal. ammo, by changing the cylinder.
