My 16 yard shooting with 7/8 oz of 9s gave me several 100s; more than before with the usual mantra. I never would have tried it had I not grabbed skeet loads to join a buddy wanting another shooter with him at the practice trap. Worked good at 25 yards too, same conditions.......breakemall
I don't smokem, they vanish, with a .015 Briley s2 Extended in my Infinity. I hope to get my strength up again so I can get away from my slam-matic with a #3 Muller that does the same thing. 1 oz of 81/2 @ 1180 will kill anything from the 16.
From the 16 yd. line you can routinely achieve solid breaks even with #9's when you do your part. For anything further back than about 20 yds. and assuming you're the kind of shooter who can put the core of the pattern on the target every time, I personally think you are short changing yourself with anything smaller than #8's.
