BEDDING 10-22s
The receiver of the 10-22 has only one stock screw. If the barrel band is to be eliminated (or isn't used on that stock) or a heavy barrel is installed, I recommend an epoxy bedding material shim placed near the end of the forend. There should be about 6-7 lbs of uplift provided as the epoxy sets up. If the receiver is bedded and there is no forend pad, the rear of the action will not be very stable in the stock.
The most common way of doing providing uplift on the barrel is to place uncured epoxy in the barrel channel about 1 1/2" long, install the barreled action in the pre-epoxy-bedded stock with the uncured epoxy pad. Place the forend in a padded vise, upside-down and hang a paint can of the desired (uplift) weight on the barrel near the end of the receiver. After it sets up, disassemble, clean up the pad edges and you're good to go.
