Chuck, I was thinking of you after the hunt this morning because this one seemed an aberration and hardly made sense and I wondered if I didn't learn something that may help with anchoring those elusive quails out there.
Ordinarily I shoot 2 3/4 shells with No. 4 or 5 TM or bismuth shot, 12ga, 16 and 20. This morning it was three-inch 20 gauge---yes, yes, I know---with 1 1/8-ounce Kent TM Impact No. 3 shot.
The SKB is light, with 26-inch barrels and I wondered if No. 3 might be the ticket for those quick, long shots among the boulders. I chose No. 3 for the third time in my life because it has been surprising me.
