I’ll almost always have something “common” as a backup. I like to hunt w/my 257Wby but I’m not building a 2nd for backup. I just bring a .270Win. Nothing wrong w/having something out of the ordinary as a primary, but the backup should be a “when the chips are down” rifle.
Often I’ll have a pair of nearly identical rifles that will shoot the exact same ammo.
I’ve not done the backup scope mounted/sighted in because I’ve been able to drive everywhere and just brought a spare rifle. If I was going somewhere that a 2nd rifle wasn’t a reasonable option I’d have a spare scope in tow for sure.
