UltraDot rings not holding

[nick50471]

I got my LBC Bullseye Wadcutter in November have 1450 rounds through her. Every 300-400 rounds I notice the UltraDot has slid forward and is resting against the front ring. I am using the aluminum vertically split 30mm rings that come with the UltraDot MatchDot. Slide mounted on my LB. I have loosened the rings moved the scope back and tighten the heck out of them and it keeps creeping forward. I just replaced the UltraDot rings with Leupold 30mm PRW rings. I hope they hold better.

I am shooting 200gr SWC with 3.7gr of BE.

Anyone else have trouble with the UltraDot rings holding?
They work fine on my Springer and RRA bullseye guns.

try a small amount of masking tape on the scope tube under the ring, this will give it more bite.
