salukipv1; According to your regs.......
"No. 4 shot is the largest and No. 7 1/2 is the
smallest size shot that may be used."
I was pretty sure that I had used #7's when I was there last.
Anyways, with an 1187 I have had good patterns with an Indian Creek, Pure Gold, and a Star Dot choke shooting Nitro #7's, Hevi-13 3" 2oz #7's, Hevi-13 3" 2oz #6's, and Winchester Xtended Range 1.75oz #6's.
Your Remington Super Full choke should be .665, the standard constriction of the Indian Creek is the same, the Pure Gold and the Star dot were .670
