Not that I have seen, yet. I may build a bolt action for a buddy of mine. At the gunsmithing school I take classes at, they built an AR and test fired it without a brake before installing the gas system...student broke his collarbone, apparently. I have more interest in it in a bolt action than a semi-auto.
That's a lot of gun for hogs in Texas! I'm from Texas and have killed a couple dozen hogs with a 10" .30-30 Contender with the cheapest 150gr ammo I could buy or a 16" AR .223 with plain old 55gr FMJ. I got fancy once and bought some 62gr JSP .223, but never did finish off that box. Dead is dead and there's nothing wrong with more gun than needed, just don't feel you have to. I'm hoping the cartridge catches on to justify building a few bolt actions in it.
