I got this idea from a post on anther thread. The member posted that he would pick a rifle for the type of hunting he was going to do, then pick a scope and mount it for the hunt. As I recall, he said that he could take a scope off and on a rifle without affecting it's POI. I thought that was very intersting and it gave me an idea.
A person could have 2 or 3 scopes to cover all the types of hunting and shooting they did and have a collection of rifles to use them on. Or even just 1 scope if fit their needs. A scope like this would have to be reliably repeatable, such as a Nightforce or US Optics, not sure what others out there fit the bill. Reason being, POI from one mount to another would be different and the POI for a particular rifle would have to be dialed in when mounted.
The benefits would be you could pay more for a higher quality interchangable scope...one scope for the price of 2, or 3, or more...
And/Or... you could use the savings on other rifles.
This sounds like an interesting idea to me and I'm going to give it a try with two or three rifles at the range sometime this summer.
Just thinking outloud
