My old beat up Manufrance 16ga SXS is a top candidate.
The Husqvarna FN/98 9,3X62 is a drop-right-on-it rifle. It seems to fall into my hands right on target.
This Franchi 48 12ga 25" barreled LW autoloader is a natural pointer on chukar. I found it at a great price on Gunbroker years ago.
A long time favorite is this Sauer cape gun 12ga-8X57JR/12ga SXS combo. When shouldered, a look through the scope confirms it pointed right, and the shotgun shoots like it was custom made for me.
