This is the cheap home brewed method I use with my rifles that more often than not works. I remove the barreled action, take a business card and place it in the stock ahead of the recoil lug and another over the rear screw. I then take an exacto knife and trim the cards to fit the stock and cut out around the screw hole. Then carefull replace the barreled action and tighten the screws normally. Then trim off the excess of the business cards sticking out at the stockline. This should free float your barrel so that there aren't any pressure points on the barrel to affect point of impact between shots. If this does work, it will save you alot of time and money on a custom bedding job. If it doesn't improve accuracy, it only costs you a bit of time, no money, and doesn't permanantly modify your rifle in any way.
