Yeah TJ.. I always used trap loads for cripples...except the real long ones. Used to shoot a lot of diving ducks at one time and found that the trap loads worked great.. easy to shoot and a whole lot cheaper than those duck and goose loads. Especially if you reloaded them anyway. And if you were laying in the front of a boat they just covered the duck right up. BTW you don't stand up in a little skiff in a big river or the bay when chasing crips. Sooner or later you will be overboard
I only have 2 boxes of those steel 6's left. Loaded in the old style WAA hulls. Still shoot good too. Luck with the duck this year
