Here's a good example of what's being discussed.
This is a Model 70 Super Grade stock I finished up a couple weeks ago. This stock was the nicest piece of walnut I've ever seen on a factory gun. It had the original Winchester bedding blobbed in there with a lot of 'wrong'. In all fairness, Winchester certainly didn't want any bedding material showing on a stock like this so I give them kudos for that.
Factory Winchester bedding:
Carefully removing the factory bedding while preserving the original bedding height (to duplicate the correct height of the barrelled action in the stock) while working all of this out with the aluminum pillars I was installing, took some time. You don't have an egg timer set for some ridiculous time.
When doing something like this, I simply take whatever time it takes....to do it correctly.
Good shootin'
