Foxy, there were a half dozen guys selling .375 ammo at our Father's Day swap meet, all of them with stories about their fathers or fathers in law owning .375 rifles. They are out there. I own two and I'm not a rifle guy. I bought some ammo even though I own more than I will ever shoot. I would hold out for one with a Griffin and Howe side mount. My London Rigby has a side mount from the original Rigby order that looks like a G&H but with no markings. I think Rigby made it from scratch. My first year Model 70 straight taper Super Grade is an iron sight gun with a Lyman 48, no extra holes.
