SR 4756 in M1 Carbine

edited September 2015 in Perry Shooter Competition Shooting and Reloading Forum
Over the weekend I picked up a can of SR 4756 powder. I grabbed this simply because I had seen it listed in my old Lyman manual for loading the M1 carbine. The max load listed is 7.3grs. and this is like a pellet gun and will not function the action. Before I start increasing the load I would like to know if there are any higher loads listed anywhere. I read somewhere that older Speer reloading manual list other loads. Can anyone provide a functional load with this powder?

    I tried it years ago, and went back to the old stand by of 13.0grs of H110 [;)]
    Couldn't get 4756 to function right [xx(]

    SR 4756 is a premier powder for the 16 ga. Others work out better for rifles.
