Wow, it's a rare thing nowadays when Oldtimr and I agree on something but as I stated long ago on this post, the only thing that is making this a SEEMINGLY shotgun is the fact that the bullet he is loading is sized in gauge rather than caliber. It's basically a straight walled, HUGE bored, RIFLE cartridge. Plain and simple to see. There is a pretty significant difference between a 12 gauge savage 220 or 212 and one of these T-Rex killers. Granted I personally don't give a rat's rear end because I honestly feel that "shotgun only" states are ridiculous. I would agree that "shotgun only" should be used in SOME areas that are a bit more populated than most but to make it a state wide regulation like here in Illinois is sheer lunacy. But hell, I can easily put down a whitetail with my 12ga slug barrel at 200 yards with minimal effort so what the hell is the point of the regulation? These things he is making are pure and simple ways of skirting the regulations. The pressures and velocities far exceed ANY factory made slugs by his own admission. That being said, if I can easily drop a deer at 200 with my factory made 12ga, just how far out could you reach with one of those cannons? I do believe the purpose of the regulation is range limitation which I personally feel we already skirt with our rifled barrels. Hell 30 years ago when Tn had a shotgun only season I was feeling pretty dang sporty dropping a deer at 75 yards! Just my opinion, which is worth just about what was paid for it!
