Got a boating store in your area? If you don't know, a boat is a hole in the water into which you pour money.
Because boats are always falling apart, Marine Stores have the best epoxies around. If you go to Camp Perry, the Walmart in Port Clinton has an excellent selection of marine epoxies.
I have picked up these 14 ounce boxes of Marine Tex for about $20.00. They contain a can of hardner and resin. This stuff has a smooth peanut butter consistancy when mixing, so it stays in place on the sidewalls of a stock.
I use a scale and figured out that the weight ratio was 1 part catalyzt to 7.75 parts resin. That way I can use my digital scale to mix up some in a paper dixie cup, and save the rest for later.
I use as a cheap release agent, Johnson paste wax. Just rub the stuff on, and in hard to reach places, melt some and use a cheap flat brush to paint on.
I use Johnson paste wax all over the stock. I always get glue on the fingers and then it gets fingerprinted on the stock. Much easier to remove if the stock is waxed.
I bedded a couple of Finnish Nagants. Changed point of impact, did nothing on group size.
