I took a half day off so I could go shooting, cause it's been raining like crazy here! Well I had some #6 Lb's I wanted to try in my 870sp with my new Sumtoy .665 choke, and my truglo strutt stopper .665, the conditions were a little windy, but they put up some good numbers.
With the truglo I got 213 in 10" at 40yds.
With the Sumtoy I got 184 in the 10" at 40yds.
I'm kinda thinking the Sumtoy just needs to be broke in, and it will put up better numbers. I even tried the LB #5's, and got 144 in 10" at 40yds. There was a bunch of folks there so I didn't get to try the #4's, but I will try them this weekend. I can say that the Sumtoy choke patterns were to the left 5" and dead center, so that proves that different chokes have different POI. The funny thing about the today is I took my 20ga 870 express also to try the #6 fed HW's, and I tried them 40yds. And got 72 in 10"! I was looking at the target, and thinking man that should have been better, and it probably would have been better if I had installed a choke! See it wouldn't fit in the gun case with the choke in, so I remove it and left it at home, nobody's ever done that right! Im going to retry those this weekend also.
