I use several types of Quick Release scope mounts from makes such as Apel to Leupold. All if correctly installed will return to zero.
Even though Apel do not claim this with their Roll off mounts I have found it to be so. In fact i used a rifle fitted with these on my hunt in Missouri back in 2003. Despite the tender caresses of the baggage apes
who's careful attention was clearly shown by the dents and scars on my new alloy and composite rifle case and the rifle being zeroed on Bisley's ranges when the scope was refitted, I carried it in my holdall as cabin baggage
, and zero checked no adjustment were required. The first shot was bit off from the clean bore but te next three fell exactly where they should.
I nearly always remove a scope for rifle cleaning if the mounts allow me to do so. I have found that even the old Parker-Hale rings and bases return to zero as do the Weavers that are fitted to a couple of rifles. The EAWswings are brilliant but expensive. The Leupold Q/R lever operated mounts work but the bases did require some lapping to fit the action profile of the p-H 1200 Super perfectly.
The only problem I have encountered was when using a set of Hilver lever operated Q/R rings with which it's possible to not get one ring on it's dovetail correctly. This was down to operator error and not paying enough attention to what I was doing. Leaving getting ready too late and rushing
. When put on properly they also return to zero.
So you pays your money and you take s your choice. Fitted properly to the rifle and set up correctly yes they return to zero. However I would say one thing I have never tried testing them as say over 200 yards as I do not hunt at further distances as a rule.
