Re: 788 accuracy
I purchased a used 788 in 6mm that was in excellent condition at a gun show a few years back. I removed the stock in order to clean and inspect the barreled action and was surprised at the amount of tension placed on the barrel. It annoyed me so much that I free floated the barrel and bedded the action before I ever fired it. It turned out to be one of the most accurate rifles that I have ever shot.
I never liked the feel of the factory stock, so I recently purchased a Boyds thumbhole stock. Just finished the stock and bedded the action. I haven't got to shoot it yet, but it is much more comfortable in any shooting position. Another advantage to the aftermarket stock is that I was able to eliminate the noisy detachable magazine by leaving extra material in that area.
The 788 isn't the nicest looking rifle out there, but it sure shoots great. Good luck with yours.
