Home Forums Reloading Bullet Casting 30 cal cast bullets question

I shoot the 300 Blackout, and have experimented with a lot of subsonic loads.

You will not find any soft point or flat nose .30 cal bullet that will expand significantly at subsonic speeds, even cast from pure lead. Your only options are the expensive boutique stuff like Lehigh, or a custom hollow point bullet. That's why I recommend a .357 barrel instead, there are literally dozens of off the shelf bullets, or even loaded ammo, that will work perfectly.

You can look at NOE bullet molds, but if you don't already cast, a hollow point rifle bullet mold is not the way to start.
