Shootall, most of the handgun 30 caliber bullets are light-88-90 gr. Sierra and Hornady make a 90 and both are dandy out of a rifle. My Automag III 30 carbine pistol shoots the Speer 110gr HP RN as tight as any pistol can shoot with accuracy good enough to ring a 6" plate at 100 yds. Same the Ruger old model pistols. But for hunting, it sucks. On a coyote at 15 yds you can almost reload the the bullet as it doesn't expand, nothing. From a rifle you may find some surplus 30 Luger bullets that will be FMJ in 88 gr. They come outa my Rockola and shoot as good as anything with a ragged hole at 25 yds. Considering what yer attempting to do with them, the twist rate MIGHT be wrong but I'd give 'em a run. Like we say in the country, Don't know if ya don't try.
FWIW, if loading for a pistol 30 carbine, the cut to length is critical. I have Remington new brass in the box that works great in the old military carbines but won't go off in a pistol. The cut to length needs to be at or just off of max length. Apparently they cut pistol chambers a little deeper as this is true of the Automag III and several old model Rugers I have. And most apparently Remington cuts their brass about 12-15/1000 short. If you have accuracy issues and are using small rifle primers, change to pistol primers. The 30 Carbine makes about the same max pressure as a 357 Mag but the pistol primers make an incredible difference.
