Well, I'm late to the party. I got a factory sporterized mark 4 made here In the U.S. by Savage. It was sporterized in England by Parker Hale. Nice thing is that it has a new Parker barrel with a standard chamber, so I dont have the headspace problem, or the lengthening problem when reloading. I slugged the bore when I first got it, took a .32 cal 90 gr bullet that I reload for the .32 S&W long cartridge and drove it down the barrel. Then miked the slug to find the groove and land diameters. That went so well that I decided to see if I could work up a plinking load with the 32 lead bullet. Trust me, I have now fired hundreds of them. I don't want to post the actual charge here, but I use a very small amount. Remember, you don't want to drive the lead bullet very fast, or you will start leading the bore. Anyway, last year cheaper than dirt had a lot of the Greek ammo, on stripper clips, or not, I bought quite a bit. It is non corrosive, and the cartridge cases are boxer primed, and are some of the nicest I have found for reloading. I have loaded a number of different bullets, from the 215 gr Woodleigh (Australian), to some lighter bullets by hornady and Remington. The Remington may not be available now, I found some old new stock at a local dealers, but the core locked bullets are great for hunting. Also the Woodleighs are great hunting rounds. If you are a mosin loader, you can use any of the mosin bullets to load the .303. Great gun. Have fun, and if you want that load with the .32 revolver bullet, PM me. It makes for really cheap shooting, and no recoil, and you really can get by without hearing protection! Lots of fun.
