Nice rifle you snagged there BIG JAKE
I have 2 375 WCF's, a Ruger No.3 and a big bore Winchester XTR. Not much to say as far as loads on this end, but a max charge of Reloader 7 from Hornady's manual and their 220 gr Flat Pt has done the job on "just a few Whitetails" and 1 black bear in the northwoods of Wis. It basically worked the 1st time, accuracy and velocity both excellent, and things don't run far after they are hit. I stuck with it since '81. Latley I have been working on some cast bullet loads for the Ruger, very promising results with IMR 3031.
Its a very easy cartridge to load for. Hope this gets you started. Crash87
