Hi Karl!

The 30 Carbine bullet is ~.130" longer than an 86 gr FMJ...

I started with a light load...And I've experimented with several powders...The M30 has a 5 1/2" barrel...My experience is empirical...

If you have doubts, then disregard...

(Lemme look here...one...two...three...ten...yes, I still have ten fingers...)
