I have been shooting this NEF Handi Rifle chambered in 500S&W Mag for some years now. The bbl has been chopped to 18 inches and LOP taken down to 12.75 inches.It wears a 2.5X Leupold with heavy duplex.
I have tried quite a few different loads with this gun including the 350gr and 500gr Hornady XTP's. My hunting load is a 440gr WFNGC (hardcast) and I have several loads shooting lighter bullets at <850fps which are great fun on steel.
The 500 in a single shot action is great fun. The gun in the middle is the 500. Bottom gun is a 444Marlin and top gun is a 45-70.
Hopefully you can get you AR running properly at the >50K psi pressures.Personally,if it were my gun,I would shoot only jacketed bullets thru it. If it has adjustable gas that should help with the "tune" greatly.
What is the actual chambering of your gun ?? 50Raptor ?? 500S&W without a rim,right ?? --- SAWMAN
