Nighthawk

I have scoped 2 doubles, a 9,3x74R Chapuis, and a 450/400 3 1/4" British double.

Regulation was not effected in any way.

Sometimes it does happen, I have been told, but several people I know have scoped their doubles with out problem.

I think ANY double .40cal and under should be scoped [with QD mounts of course].
