The bedding on some .22's is a little counter-intuitive compared to bigger rifles - especially if you only have 1 bolt holding the thing into the stock. If you have an accuaracy issue then play with it by all means, but if not don't break what ain't busted...
I had a Norinco JW10A (a Stirling knockoff which in itself is a bastardised BRNO design I think) - this was particularly accurate but the main issue was it randomly selected which point of impact was going to be the one for any given day. It wasn't until I shot the thing at the same target over some weeks that we worked out why it had such a poxy hit rate for such an accurate gun - basically crap timber that was dense down one side and balsa on the other. Took a couple of goes to get the bedding 'right' and it went from a 1/2" group with random impact points depending on today's pressure on the barrel to 2" centered groups, and on the final go to 3/4" groups with everything it was fed including random mixes of ammo. I gave up after that and it was still doing that when I sold it!
