I have had 2 of them, A .204 and a .22-250, I went thru several scopes and checked the bases on both and still could'nt get them to shoot a 3" group at 100 yards. I don't know what the problem was but I'm about the only one that I have heard of having a problem with getting them to group. I would still really like to have one for a truck gun but I want it to group.
