Shot a single test pattern from my 1300 with a Sumtoy .562 and Apex 9'S. Really liked the 10 inch numbers but where did the rest of the 300+ pellets go? The 2' square paper only shows about 80 holes outside the 10" circle. Over choked? 7's instead of 9's? Not filling the shot cup?(https://uploads.tapatalk-cdn.com/20190610/d8f0063f53f1a9e7c282914ea7ef8ec1.jpg)

Looks like it could be overchoked. Your 10" looks really stringy and there isn't much uniformity outside of the 10". To be fair a .555-.562 choke in most guns is going to get you either A. A hot core or B. A blown pattern. That's not always the case but in your situation my money is on it being overchoked. If that gun liked the .562 you'd be at 290+ in the 10" all day long.
Hard to imagine 230 pellets flew somewhere off a 24"×24" piece of paper but I guess anything is possible. I personally question the size of shot. There should be 588 #9 shot in the 1-5/8 Oz load.
I hand load and have a buddy that does too. He just shot a well known load out of 870 20g to try for giggles yesterday. 2 3/4" 1 5/8oz load. His current 2 3/4" 1 7/16 oz load with 9s out of his 870 does 270/190 on average out of a .562 Sumtoy. The new load went 173/82. Half the load was nowhere to be found. Puts in a .585 Trulock and the same load and same gun goes 270/250...it's very possible. I'd give a more open choke a chance with it and just what happens.
A load of 7's seems to be the most likely culprit.
Did you ever figure out the problem ? ... very interesting .....

Not yet but will be shooting again either Wednesday or Saturday. My gut feeling is this shell was loaded with something larger than #9's.
Well let s know what happened
Pretty sure this one shell was loaded with 7's instead of 9's. Here's another pattern of the same gun, choke and Apex 9's.(https://uploads.tapatalk-cdn.com/20190810/ef94e58d618a83394666da77117afca3.jpg)

Sure looks like it 8.5 shot maybe. 500 shot in that apex load from their site.
7.5 shot would have 358 in that load. 7 shot around 300?
