I've had problems with the first round jamming while chambering in my g30's 10rd mag but fixed this by using their latest hi cap follower and a new mag spring. I've been using the factoty recoil spring.
I don't know if there's a performance difference between .45 brass and .400 Corbon brass, but, since .400 Corbon has a little more case capacity than 10mm; it takes about .1gr to .2grs more powder in the .400 Corbon compared to the 10mm case to equal 10mm velocities.
Brass can be ordered directly from Starline;
By changing to small pistol primers (WSP recommended), small rifle primers (Remington 7 1/2 recommended) can also be used.
