g'day and welcome to the forum

i'm a nutcase inventor who likes to shoot and help others to shoot

wheel chair folks and other less abled

the folks have told you straight up

springs as matched as best you can will wear and recoil at differing rates no matter what you do

so two springs are bad

however

seen them old old springs about 3-4" long ?? they pull the wire net in bed bases tight

i've affixed a single one of these to a wheel chair shooters front board over a sand
bag

and thats stopped the rifle recoiling into their ribs as they cant lean as far over as they wish so we also have a scope that outputs to a 10" pc screen so they can sight it but not via the scope directly but via the video output

its doable but you gotta set it up well

i've a bum shoulder and cant shoot the big stuff all day either so mainly use .22's or BP as these dont affect me so much

cheers
