all that you said -- I lost and found the two does several times and finally got one just before they left//when we tired to adjust the eye relief -- it is locked will not move by hand -- the scope is a new burris 4X pistol scope-- -- I think we are going to just send back to them tell them the problems-- and use another 2x we have here-- and yes 70 yards is pretty normal for my hunting except on two farms I hunt and then 250yds is more normal--- I have not shot this weapon much as it is my sons and up till now had not messed with the eye relief-- I guess he thought all that was normal until I told him other wise
