Have had a summit for a few years, has been on a 30-06 and seen little use.

Put in on my .375 today, took it to the range, and when I was sighting it in, it would impact consistently left of point of aim. Began about 12 inches off and I dialed it until it was 2" to the left and then had no more room to adjust the scope.

I assume I've got a broken scope, but am hoping there is an operator error that I can correct as I'm heading to Africa in several weeks and had hoped to use the scope.

Thanks for any ideas.
