I'm in the process of choosing two scopes, one for an 06 and the other for a .300 WSM. I was very interested in the Muellers, but noticed that in the fine print it said not for larger calibers so I emailed them and asked which of their scopes could handle .30 caliber and up and the only choice is the Tac ll. This was not the one I wanted so that rulled out the Muellers. Two friends of mine have .30 calibers with Burris on them and are totally satisfied and both scopes sold for under $250.
