OK, decided to pull a 2 x 7 lupy off a Marlin 45/70 and mount it on my Ruger Hawkeye 358W. The Leupold's take a #15 torx while the Ruger uses #10's... Now is it just me or do you chaps have trouble twisting and or ruining your bits on tight screws? I seem to get along fairly well on the tightening of the screws, but after they have been on a rifle for a spell, and grown roots, they take more force to remove and the torx tools I use don't last long. Anybody got some tips or alternative's???
