My recommendation would be to use gas checked bullets. Some of my loads are moving close to 1600 fps. Even with plated bullets......Berry's recommends using their "thick plate" bullets for loads above 1500 FPS............... very easily accomplished in a carbine length barrel. I get some minor leading with PB, none with GC's. I have reverted to putting aluminum plain base gas checks on bullets I intend to use in the carbine. Any future moulds will have GC shanks.
I had some pistol developed loads on hand using an older lot of AA#7 and Lyman's 120 TC plain based bullet. Eight grains was producing 10 shot groups of 2 MOA, from 50 yards, using a camera tripod for a rest. Ran out of that lot of powder and bought a new 8# jug, especially for 9mm reloads..............I have half dozen 9mm chambered firearms. Was unable to duplicate, with the new lot of AA#7. I don't know what Accurate did with the powder but I can't load eight grains without compressing that non-compressible powder..................that 120 TC bullet is starting to deform/meplat, is significantly wider. COAl's are shorter, at the same seating die setting, when try I go above 7.3 grains. Alloy is pretty much the same..............14-15 BHN and air cooled.
I have not found RN bullets to be as accurate as FN or TC, at the longer ranges. This being the case, regardless if I use cast or plated.
Other powders, I have tried are Bullseye, Unique, N-340, 231, and Power Pistol................... all do fine, nothing earth shattering. Most result in sooty cases............ charges ranging from mild to wild. AA#7 leaves quite a bit of powder granules in the action. However, I modified a hard plastic brass catcher, designed for a AR. I'm not chasing brass, but it doesn't allow the granules to escape.
