The factory crown, while not a "target" crown, did not look bad. but just the typical "rounded" end of a barrel, with a real crown about .06" deep at I would guess about 45 degress.
I had it recrowned, simply to have it done. My first time to send a gun out.
A person from rimfire central did it, A .22 benchrest enthusiast,he is about an hour or so away from where I live. The simple, and somewhat minimal bedding I did (not a pro!) also had to help. The result i really liked the best....was that those targets, the action screws are nice and tight. no action screw "exact settings" games to play!!
Only the Magazine seems to be the cons to the Z5.
it can shave/deform a lead bullet - because the spring? is really stiff, and requires way to much force to load the magazine. I even gave up on loading 5 rounds.
I single loaded for these targets.
Heard that Mossberg Plinkster mags can be easily modifed to fit.
