I will soon be mounting a scope on my .338 Mag and was looking for advice on what I should apply to the inside of the rings to help insure that the scope remains solidly in place once mounted. I have no experience with rosin at all, and have only tried using rubber/multi-purpose cement once. I was disappointed with the small amount of cement that actually remained in the rings and further diappointed by how little if any helf it seemed to give. Are their other additives out their? Which of these two would you recommend? etc. Thanks.
