A.J. Aubrey had it all 'figerd out in 1908, at least that's what the Sears catalog said wink
"Shooting qualities - As before explained, the shooting qualities of these guns are unequaled for long distance killing, long range shooting, for penetration, pattern or target. Both barrels are full choke bore, so firmly constructed that unlike other guns, there is no recoil or kicking. That which in other guns goes into recoil in the A J Aubrey gun goes to give greater force to the shot."
