Erik,

I have Talley QD's on my 375H&H. I like them, however, in my trails the repeatability has not been perfect. Shooting, removing and remounting will have my group move up to alomost an inch at 100yds. IIRC, this move was almost always right or left with not much change in elevation. I tried being very careful with the torque I applied when mounting and tried snugging the rings in alternating fashion, an eigth turn on one, then the other. It made no diffence that I detected, the POI still moved some.

I have another scope with the Talley QD's and when the weather improves here I will try that one for repeatability. Hopefully that will be soon and I will let you know how it goes.
