Does 300 BO in an AR run cast bullets without lead getting into the gas system?
Just taking a guess… You’ve “heard” from perhaps a trusted friend, or maybe even read somewhere that lead can PLUG the AR’s gas system? It’s a Shooter’s urban myth. Lead can’t hurt the gas system even a little. The AR15 faces the same issues using lead that that any other firearm does. The lead leaves deposits in the rifling lands & grooves. Not to mention any microscopic imperfection becomes “leaded”. That’s all. It’s just fouling, like any other fouling. No, it’s the good ol’, run of the mill Nitro (Carbon) Fouling that “can” plug an AR’s gas system. However, this would take some serious neglect of cleaning & many, many firing sequences to actually accomplish.
