That's a tricky question because people shooting SS barrels usually have good glass and want more accuracy than most shooters. But at least 5K for what I'd need out of it.
The guys buying Jacks are doing drills between 7-100 yards, with a LOT of that being under 50 yards. For their intended purpose, that barrel will last well over 20K rounds. Long enough that they'll never have to really consider it.
