For me, I am like you. No matter the hunt I basically have enough backup rifles for everyone in my group.I run 20MOA Picatinny rails on every rifle I own.
They allow for more adjustment in mounting scopes.
They allow a broader (and dare I say better) choice of ring options
Swapping a scope (if needed) becomes quick and easy. You can even have a 2nd scope zeroed for your rifle in case of a drop out in the field while hunting.
When I go on a hunt, I am a crazy person. I usually take 2-3 rifles (or 4...), AND have a back-up scope already zeroed for my main rifle just in case of a drop that might leave a lingering question in my mind. On occasion, I have actually had to break out a back-up rifle a few times for a hunting partner when something happened to their only rifle they brought.
I have had to use a backup rifle once personally, and once for a friend. We had to use a backup shotgun on our sandhill hunt a few weeks ago too.
