In a lot of the more inexpensive .22 rifles, there is only one screw to hold the action into the stock.
I have found that drilling and tapping for a second action screw (similar to big game rifles) will do a lot more for the accuracy than a simple glass bedding.
Of course, you could glass bed and free float the barrel after you put this second action screw in. Some rifles respond to opening the barrel channel, and some do not.
A good trigger system is essential, preferably one that is adjustable.
There is probably a long list somewhere of things people have tried, but expense is the factor. You can not compare a Cooey with a CZ, and the price reflects it. I still have my old Mossberg 44 US that I started target shooting with back in the 50's, and I did all right in competition with it. But, it certainly does not compare with my Kimber 82G.
Another factor is the use for the rifle....general hunting or plinking is not like shooting Benchrest or Olympic targets. What level of accuracy do you need and are willing to spend the time and money to get?
