My new wildcat is a 375 Taylor, which is a 338win mag necked up to 375. Velocities equivalent to the 375H&H, ballistics on par with the 308. f**king brilliant, I must say.
It is being built on a FN/Browning Mauser 98 action, a Pac-Nor 24" chrome moly barrel, custom california walnut stock, and that is pretty much all there is to it. I will post pics when I get her all built. Could be a while...
