I have four of the 4.5-14's with the ballistic recticle, I have them on a 7mm mag, 300 wsm
, 270 wsm, and 264 win mag. I have never had one move after I have sighted them in. Clicks may not be exact but fairly close, glass is on par with VXII. I purchased mine as a package with the spotter, and then sold the spotter for $50-75, which made it more affordable. Hope this helps.
