I just got done bedding my 597. I used JB Weld and liquid electrical tape for a release agent. I was skeptical at first but after doing it, it worked great. I just thought that I'd pass that on because I wanted to bed my rifle but didn't have any release agent and I didn't want to buy some from brownells. It only costs a couple bucks and it works very well. Again I thought I'd just pass that on.
