Just asking is all.
The .22/243 stretches cases no worse than others do, so cases are not "fire once, and throw away". Load 'um until the primer pockets get loose. All that's needed to make .22-243 brass is to neck down new .243 Win. brass. It's a bit harder on barrels than some, not as bad as others. Load it reasonable and don't try to fire it like a machinegun. Loaded and fired sensibly, it'll run 1000-1400 rounds before she's toast. The .22-.243 is at its' best with 'heavy for caliber' bullets. The 80g SMK may be accurate in a .22/.250, but it doesn't have the needed velocity for LR, it runs out of 'steam' before it gets there. The above is not a bunch of guesses or assumtions.
