I have had zero problems with my LCS 45x on a 30.
But, Shinny believes that he has, therefore, he needs to solve the problem.
There are three methods:
1. Lock the scope up and use external adjustments.
2. Buy a different brand of scope. Preferably, one that the heavier recoil folks use.
3. Quit shooting.
Many of the folks shooting 30s in my area use the NF BR. They have a reputation of being rock solid. OTOH, they are heavy. If you're shooting a 13.5 lb rifle, though, it's doable.
Right now, with the NF Competition on the scene, you are seeing NF BR models up for sale at decent prices.
