This symptom is typically caused by slippage of the scope in the rings, you should tighten the ring screws to 15 inch pounds or so. Many ring sets are slightly misaligned or poorly machined.
If you continue to have problems, you may need to use a ring lapping/alignment tool (available from midwayusa, (http://www.midwayusa.com/Search/#wheeler%20scope____-_1-2-4_8-16-32). This will increase the surface of the ring that actually contacts the scope, thus increasing the clamping force and friction to keep the scope in place during recoil.
Don't know what type of rings you have, but Leupold makes excellent rings. I have not found it necessary to lap these rings to date, even on my 45/70.
Other issues may include loose mount screws or loose ring to base mounts.
Mount your base screws using 15 to 20 inch pounds of torque and blue locktite. Torque your ring to base screws to 30 inch pounds or so.
If the scope is slipping in the rings, a quick temporary fix that might help is to apply rosin to the inside of the scope rings to increase friction. I have also used a dab of rubber cement as a temporary fix.
