HQ, the obvious answer is a low cost bearer.
You already have a wife or significant other (SO)? If so, you're paying for it. We all do.
So, what you do is invite the SO on the hunt under the guise of "sharing", then have she, he or xe, carry the heavier of the shotgun or rifle; also "sharing" .
Worst case: no more SO on hunting trips and you have to buy a Tikka compact and a new super light shotgun. Otherwise, the SO becomes bearer, therefore adding efficiency to the relationship, and you can buy a full size new Tikka in 30-06 anyway since you don't have to carry it, keeping the 7600 as a back up. A few sweet rakastan sinua in the SO's ear and Olavi is your uncle!
