Like 125JHP, I've run N-350 with 230 grain bullets - I chronographed the Remington 230 grain brass golden sabers and 7.5 grains got me 915fps from a 5" barrel while 8.0 grains turned 983fps. Groups were around 3" at 25 yards with 7.5 and just a tad larger at 983fps.
Now with the Super you can run the N-350 with 265 grain cast bullets and with 8.0 grains you can turn 1,004fps and 8.5 grains will fly at 1,061fps. This from a 5" barrel. The case will hold 9.0 grains with minimal compression, if any at all, with the Beartooth 265 grain cast gas checked bullet with an OAL of 1.245.
My particular pistol is well set-up and will consistently shoot under an inch at 25 yards with the 185 grain Nosler or XTP using 4.1 grains of N-310, so I can accept the 3" groups hot-rodding the 230 grain. I went with a heavier recoil spring in the 1911 with the super loads using super brass just to see what I could do and it wasn't pretty - you can keep everything on a 10" pie plate with plenty to spare but that's about all I can say for its accuracy at 25 yards. I think there's a need for a faster twist barrel there.
