I agree, handloading for the .375 is the way to go. I can load mine from .38-55 pressures shooting 255gr LFP up to full power .375 shooting 220 gr Hornady JSPs.wingnut; you should seriously reload for that 375 Winny, I have been reloading for mine for 5 years, and love it!
I can load cast 38-55 bullets @ lower (38-55 ) velocities for plinkin fun, or "souped up" jacketed loads for hunting.
I have yet to bag a deer or bear with it yet, but I'm still trying!![]()
