I've had my CZ-452 Lux now for several months. I shoot it quite frequently and am always impressed with its fine handling and shootability. However, one particular problem keeps vexing me and won't go away.
I have the Lux equipped with a 4x34 Kronos scope with a one inch tube, attached to the receiver via Millet angle lock scope rings. I usually shoot either Winchester Power Point 40 grain standard velocity, or CCI 40 grain standard velocity. I have the scope zeroed for 50 and 100 yards. Usually, I can drop every round into a 1.5 inch circle at 100 yards, centered on the point of aim. However, sometimes, with no predictable pattern, my shots will be thrown off in a tight group, about the same size, between 2 and 2.5 inches to the right of the point of aim. This isnt a string, or a couple of flyers... these are complete, well centered groups off to the right a couple of inches.
This one I took from a bad angle... but trust me, its off to the right, not straight up.
And here is a group over a great deal more shots.
I've had it happen from a cold barrel or from a hot one... with a clean barrel or with a dirty one. And I'm quite careful not to let my barrel contact anything, resting only the stock on the bench. The rings are quite tight and I've marked the windage and elevation drums so I'd know if they'd been moved. I've put well over 1000 rounds through the rifle now, so I think if it were poor shooting on my part, I could pin it down...
Does anyone have any suggestions as to what it could be and how it might be resolved? HELP!
