I'm working on a #5 rolling block stock. The action has a 1901 patent date. Fitting the stock is giving me fits with the angles and multiple surfaces that have to be mated. Is it accepted practice to cut a 90 degree junction at the back of the action where the stock meets the action side walls? The action currently has the original wedge shaped junction. I'm thinking it would make fitting a new butt stock much easier. I plan to remove the hand guard recess on the front of the action and thought I would check with more experienced guys to see if altering the butt stock junction is common? Would removing the small amount of metal make the action look strange? Thanks for your consideration.
