I am interested in a Winchester 501 (same as a 101, I believe) trap gun with a parallel stock (about 1-1/2 at heel and comb. I would like to use this as a sporting clays gun, but even on my best days am prone to shooting over targets. Four questions: (1) can a stock be bent straight down 1/2 inch or so? (2) can the stock be bent right (cast off) at the same time about 1/4 inch or so? (3)If the foregoing is possible, will it last or revert to its pre-bent shape? (4) who would you recommend to do this stock bending? Thanks.
