A little patterning advice

[u/SARKID_MKE]

r/Shotguns looks like just a lot of gun-porn, so forgive the off-topic but I'm bringing it to the subreddit that knows a thing or two. I have a conventional question about an unconventional shotgun. I hunt with a PBBA Pro-20, which is a 20ga air-shotgun. It's a cylinder bore, but later versions than mine were threaded for chokes and I'm considering having it threaded. I patterned at 35yds with a variety of sizes of steel and bismuth shot, as shown in the pics. #6 steel is 1oz, #3 bismuth is about 25grams.

In the sub's opinion, am I getting good patterns? I'm mostly duck and dove hunting with 35-40yd shots, and I'm missing birds that I am confident I should be hitting. I'm wondering if my pattern is too loose. The google-fu just turns up a lot of non-answers and advertisements when I try to search for normal 20ga patterns.

In the field I'm mostly shooting #6 steel with a commander wad, and #3 bismuth with a commander wad. Don't mind the low pattern on some of those, I've since raised the cheek piece.

What velocity would you be expecting out of these? Some of these are lower because the higher shot weight and lower velocity?

Hard to say. I don’t have a chrono and it’s such a niche thing I don’t have comparisons. I really do think it was the cheek though, it was really low. I do have an acquaintance that regularly hunts geese with the same gun, so I shy away from a velocity problem at only 35yds. Good question though.
