Does anyone know how difficult it would be to lengthen the throat on a rifle? I bought a 7MM Rem Mag and have to seat bullets extremely short to stay .010 - .020 off the lands. Heck, even if I seated them .010 into the lands, the OAL would still be .150 shy of what the reloading books all say. I'm used to being able to load longer than OAL, as that is usually something dictated by magazine length, not the throat of the chamber. Any thoughts?
