Today I had the time to run out to Mac's Gunworks and shoot his new creation.
Put 25 rounds through it, from the prone position, with my typical one hand hold.
Lawton action, McRee stock, McGowen barrel, Lawton picatinny rail, Mac brake, Cerakote camo, Vortex Razor HD 5-20 Scope, Vortex Rings. All the work was done by Chuck McIntosh. The cartridge is one of Dave Viers. Take a 408 Chey-Tac and partially neck it down to .375 and make a false shoulder, fireform it and you have a 375 Snipe-Tac. Jamison brass, 150 grains of H-50BMG, and a 370 grain Rocky Mountain bullet. What a cool combination.
223 Rem, 338 AX (338 Lapua Improved), 375 Snipe-Tac, 243 Winchester
