Mike, only if your old Enfield is really pristine would I hesitate to shoot cheap corrosive ammo in it. Assuming your rifle is in average condition, go ahead and shoot that corrosive ammo and enjoy the hell out of it. Just pay attention to cleaning it before that day is over. I've also read that it's a good idea to give the bore a second or third light cleaning over the next few days to remove the corrosive elements that penetrate into the pores of the steel itself and "seep out" slowly over time. I think the salts involved will weaken the brass cases, too, so plan on throwing them away after firing instead of reloading them. As I understand it, corrosive primers were used for so long in military ammo by many nations because the resulting ammo was and still is so reliable and long lasting if stored under halfway decent conditions. The .303 British is one of the great old rounds that has killed everything that walks, crawls, swims, or flies at one time or another. I hear it is still very popular among average hunters in Canada. A .303 British Enfield was my first high-powered rifle. I bought it and several boxes of ammo for about $15 in Chattanooga around 1961, then brought it home to Central Florida, wrapped up good in an old piece of blanket and sitting upright between my knees on a Greyhound bus. Nobody even asked me what I had. My old aunt I was visiting let me buy it while I was out from under Mama's thumb for a couple of weeks.
