I happen to know a couple of rimfire benchrest competitors. None of them could tell me just how much better Cecil's conversions work.
I understand the latest fad amonmg the benchrest crowd is freezing the scopes internal adjustments and going to external adjustments. That tells me the fancy locking system that Cecil designed really doesn't work.
Last of all, when asked to include some sort of locking design on their benchrest series scopes, Leupold refused. Why ? They have given the benchrest crowd everything else they asked for.
I believe that Leupold probably considered it and decided such a design created more problems than it solved. E
