I recently purchased a set of Randolph Machine offset rings for my K31, they attach to the sidemounted 3/8" dovetail and provide a 3/4" offset to get the scope closer to the bore centerline. Shot it yesterday with the RCBS 165 Sil @.309 and 18.5 grains of 2400 with Win LPP. Only 5 shots @ 50 yards but managed a respectable .500 center to center. The rings also set higher making it a bit easier off the bench.
