Fishingfool I have a 7mm Savage model110FP that has EGW 0moa with the SS 20x on it with Burris XTR lows and the height is just a little higher than the 2 others with Burris bases and SS tactical rings(same as XTR), the 3 are all mod. 10FPLE. The cheek weld is fine for all of them and eye relief is right on. With the Savages eye relief was tough to get, with the Burris XTR bases I had to grind then file some off the rear base so that the adjusting ring could move. On the EGW one piece I had to cut the last section off the base so that the objective bell wasn't resting on it, real pia to get it right. On other Savages I own I use either 1 piece Leupold or the 2 piece Leupold bases and rings with no adjusting problems what so ever, but I like the look of the XTR better so I will probably use them again for the 260 rem build I am starting on a model 111 action with a Shilen barrel and a Boyds thumbhole stock.
