Re: Idea for a 7mm Wildcat

The 375 Ruger case is way smaller in diameter than the Dakota case. ( .532 - .542 )and the RUM case is .545.I'd bet the 375 case is actually even smaller at the web than what the drawings show, which is pretty normal! The 375 is a little longer but not enough to make up for all the volume lost through the much smaller diameter. I don't know what kind of velocity the Ruger case would achieve , given equal pressures, in comparison to the STAK or RHB cases. --- RHB

    I'm planning on building one very similar to yours, just not sure of the reamer just yet. I've been reading a lot about what GAP has been doing with the 6.5 SAUM, and I think this will be a larger version of it. I'm wanting 3050-3100 fps, with the 190 gr Matrix, and 26" barrel. I'm thinking it will be a fairly light load (psi) for much longer barrel life. Be sure and post your rifle and load after it's finished.
