The crown could also easily get a ding and is said to be the main cause of acquired accuracy problems. It’s a 1 Minute job to recross apparently not too technical so don’t pay a lot for it.
How accurate is it now ? My JW15 shots about 1cm spread of Centers at 25 yd but 3cm at 50m. If you need to shoot 50 then get paper and do 3 or 4 x 5 shot groups plus one with a good target ammo like elegy Marchand you might find accuracy is still fine. I think 2cm dread of Centers at 50m is good but if it does that at 25 it could still be perfectly useable.
