Brewman, can you give us the stock model No for your CZ 550, approximate cost & who did you get it thru here in Oz please?
Not sure what the go is for "synthetic" stocks, heard that you still do bedding/releiving on them like a wooden stock - but only to take out the variations in the new stock itself.
If there is a bedding block within the stock I wouldn't bother about it (barrel channel relieved of course)
Hope some of the other guys chime in here, only really have wood stocks on my bigger stuff, sorry but a .223 in a synthetic stock doesn't count in recoil!
