My favorite bullets for 30 Carbine are cast from wheelweight metal using Lyman's 311316 gascheck moulds. I have both the round nose flat point mould and the same mould with Lyman hollow point; both purchased online at ebay. Casting just slightly frosty and using the water-dropped, heat treating technique I get bullets hard enough for standard 30 Carbine velocity (1900-1950 fps) loads. I use gas checks to prevent gas cutting the bullet bases; which can cause barrel leading and clogging the Carbine's gas port with lead particles. Size to whatever diameter is best for your firearm. I use LBT Blue Lube and leading is absolutely minimal. Solid bullets weigh out about 115 grains and hollowpoints about 106 grains; reasonable weights for 30 Carbine iron sights and loading data. As a result, I get cheap bullets, that I make myself, for inexpensive reloads, that work well in my WWII/Korean War vintage carbines, which are fun to shoot at cans, paper targets, and plastic bottles full of water and keep the coyotes away. Use appropriate reloading techniques and cautions; there's no reason to try to hot-rod these into something they can never be.
