I'm in the process of having my first 6mmbr built by clay spencer. I have a leupold varix 3 6.5-20 for it and I was wondering who still boost the power on these scopes I heard premire reticle doesn't Fool with them anymore. And has any one tried one of the screw on boosters from bullzeye pro. It would be nice to return the scope to normal with out all the hassle
