I thought I had heard or read somewhere that stocks with through bolts could not bent by traditional means, and the only way to adjust drop or cast on those stocks was by changing the inletting. Some posters on another forum recently opined that through bolt stocks could be bent using heat as well. The gun in question was a Beretta 68_ with a pistol grip and a through bolt, which did not strike me as a good candidate for a traditional bending.
Has anyone here had a through bolt stock bent successfully using the traditional methods?
