I have tried Leupolds fixed 4 power and 2 power scopes out of those I prefer the 2 power but I now have a couple of the T/C 2.5-7 scopes that I like and would reccomend. Mounts are another thing, I can't find anything wrong with the weaver type base and rings, had a set on my 308 encore barrel and it never moved, the Burris base is pretty good as well but when I switched from Encores to Contenders I tried the T/C one piece mount and realy like it at least for a pistol.
