?The Beast!? Denny Williams named it! The action is a non-designated single-shot Lawton model 8000, Jewell trigger, Bartlein 1-7 twist barrel, T-5 Terminator brake, with a McRee chassis. Chambering: 375 Chey-Tac! Seekins rings and the scope is the Vortex Razor HD Gen II 4.5-27x56 FFP Load development hopefully this week. Thank you Robert Vestal. I have another 1-8 barrel that is chambered in 375 Snipe-Tac that Chuck McIntosh built. This is a switch barrel specialty pistol.
