Update 3/27 see #39 below.
Have a 7RM with a 24.7" barrel and a radial brake on the end. Paired with a Zeiss Conquest v4 6-24x50 and Seekins 30mm rings. Scope will slip literally within 5 shots and slips every 1-2 shots afterwards per shifting POI and the pencil witness marks on my scope moving. Moved about 1-1.5mm in 9 shots.
The scope continuously slips rearwards (toward the butt of the rifle) in the rings regardless of what I do. I sent the scope to Zeiss to confirm that it is not out of round or out of spec - it's not, don't have the measurements they gave me right now, but off the top of my head nothing looked wrong with the numbers.
Info:
Have the torqued to 22in/lb (max per Zeiss when I called them). Torqued in normal star pattern and then torqued again once everything was tight, measured per Borka torque wrench.
Added powdered rosin - didn't help.
Did not alter the inside surface of the rings or the outside surface scope in any way. Also called Seekins for ring warranty and they sent another set - didn't help.
Tried ARC rings as well and had slippage too.
Have a radial brake at the end of the barrel - not sure if the change in recoil impulse is related to this but I've seen bigger rifles with bigger brakes that would induce a "faster and jerkier" recoil impulse (i.e. the jerk function) not have problems with "similar quality" rings.
Am not using a particularly hot load, heavy or light projectiles, etc. - i.e. all well within book limits for projectile weights and velocities.
Scope is not particularly heavy - 24.3oz - not sure if this has to do with anything practically speaking
Don't think it's how I mounted anything - have other rifles, including larger cal, and none have a scope slippage problem this persistent. One other rifle did have a much more minor slippage problem (much less slippage in 50 rounds) but that was resolved with 22in/lb on the rings (up from 19) and powdered rosin.
The rails do not slip in their pic slots and the scope base does not slip either.
Any ideas here or just get different rings? If different rings is the solution, any recs around or under $150ish - would like something not too large / heavy as this is a hunting rifle but don't mind something with a little weight to it. 1 piece mount isn't possible with the rails on this rifle.
