I have a surplus .30 carbine and have just bought a Ruger Blackhawk in the same caliber, Does anyone shoot lead bullets and if so which one and what load? I do know that you shouldn't shoot lead bullets in a gas operated rifle but I also know that some people do. I don't mind cleaning the gas port more often but I do hate trying to get a bunch of lead out of the barrel. Are the Ruger Blackhawks bad about leading in this caliber? Any comments would be appreciated.
