cbhausen, thank you for the advice. I had thought to use this as a truck or tractor gun, but don't want the hassle of going SBR. This is truly a niche firearm. This one is going to be rehomed, as soon as possible.
If I recall correctly, in the late 90s a bolt action, 50 bmg pistol was built, and the guys 13 year old daughter did the demonstration shooting. I'll have to check the old FCSA Very high power magazines for the article.
Supreme Court said that Epa can't make laws. How would this affect the Atf? Basically, the same abusive actions.
Any thoughts from the knowledgeable people?
