I bought an MRC stainless LH magnum action years ago, with the expectation to build a .375 H&H. Then I stumbled upon a like new M70 LH .375 rifle. I ended up selling the MRC action and wish I never did. I'd love to build a really big bore like a .404 Jefferies, .500 Jefferies or .505 Gibbs. No real reason, just to play with.
