I have a regular Encore and i have the med. height Talley one peice mounts. With a Burris 3x9x40 on my .50 cal and a Nikon 3x9x40 on a .280 barrel both have about 3/8 inch clearance on the barrel. I also can get by without a hammer spur. A freind just used the same mounts on his pro hunter and was able to get a 3x9x50 Zeiss on his with med rings. I think med. would be the way to go. Personally I like the Talley one peice because it fits cleanly on the gun, is light weight and is simple(one peice.) Most on this forum will surely recomend the Warne rings over the Talley because they are steel and the Talley is aluminum. I have had no trouble with mine and neither has my freind. You just need to look for yourself and decide. As far as windage adjustment goes I have seen no need for it, so far mine were very close. Hope this helps.
See Ya!
