Quite frankly, anyone who locates .303 surplus at a "fair price" will be buying all that they can of it. We old farts have a case or three squirreled away for special occasions, and most of it is those prized reloadable Canadian 44 or 45 dated rounds.
Reloading is the way to go. For under 200 yards, a cast bullet with a developed load is just as accurate as Mark 7 Ball, or maybe a bit more so. Some sight adjustment may be in order, but a good cast bullet load will do the trick, and is easy on cases and powder too. Lighter 123 grain bullets for the 7.62x39 can be made to work with a bit of load development, and out to 300 yards are quite accurate.
