Re: How to separate an action and a stock that is bedded together
I did a poor job of applying release agent once. (You soon learn!)
If the freezer doesn't work by itself, you can try to do a rapid temperature change with a heat gun. The beding is essentially an epoxy compound. Cold makes it brittle (several degrees below 0 cold) and heat makes it slightly soft - but watch for the stock finish with the heat.
If all else fails the last result, unfortunately, is a pocket knife.
