It's gonna be very close depending on your smith. Mine has just built 6 of them over the last 4 months or so, several of which I have shot. An action is going to run you a minimum of $1200. Barrel, $5-600, you're going to need a "killer" brake, at least $200 if you're lucky, $275 for a Terminator T5 and I wouldn't recommend anything less efficient. You need a killer stock too and a standard A5 or equivilent is too short for a proper balance (I'd go a 32" or longer barrel). So be it a chassis, a McMillian Supermag with the sniper fill (for more stiffness) or ever better one of the new long Manners jobs (about 4" longer than a Supermag) $800-to $1000 there. Chambering, threading for brake (& timing if you go that route), bedding, tax, shipping, yada, yada, could easily put you well over, it really depends on who builds it. Throw in a decent trigger & trigger guard another $300-400 or more. If it was me, I would allow and plan around a budget of $3500 at least and if you can bring it in lower you did good, go out and celebrate! And this is all assuming you have a good relationship with a smith! There are alot of these 375's around these parts and many have easily paid upwards of 7k for them! Good luck, they are really fun rifles to shoot.
