Please let us know how the medium rings work out on the 77/22. Is your rifle the blued/walnut sporter type or one of the heavier barrel models? Also, I'm assuming the Leupold 3-9 you are referring to is the VXII 3-9 Rimfire model. Please clarify as I'm looking to buy a pair of 77/22's, probably tomorrow, a 77/22 R and a 77/22 RM, and my scope of choice is the Leupold 3-9 Rimfire. Thanks!
