Anybody shoot these?

So my OPSol adapters arrived and after a very easy installation into my Mossberg 500 12 gauge, I decided to give it a try and see whether or not it was worth the cost. In my experience, I tried the Aguila 1 3/4 shells with 7 1/2 shot in them first, and I also had some slugs which I tried after. After the 20 second install of the rubber adapter, I loaded the gun with 8 rounds in the gun and 9 with 1 in the chamber.
I was very pleased at the pattern of the 7 1/2 shot at 25 ft. I then moved back to 15 yards and still a decent pattern.. I had some balloons blown up and took them with me to see how well the shells shot. I killed all 5 balloons with the shot shells. There are a few things to consider,

1.This gun was brand new and never shot before these were shot through them
2 I had never shot this gun before bet have shot others
3 I was not running them through as fast as I could
4. It took a few shots to get the feeling of it in my hands. With more shooting I will progress.

My opinion of the 1 3/4 shells is yes, not as many bb's but still enough to kill birds and squirrels etc. I would not suggest for ducks, geese or turkeys as I don't think the killing power is there for them unless closer, which is expected. I also don't think the slugs, which ran flawless would be great for deer etc. unless close. They also shot a decent group, but the shooter sure needs more practice.. Both the shot shell and slugs cycled without absolutely no issues, misfires, or not chambering at all. After I was done shooting these shells, I tried some reloaded AA 2 3/4 as well as some new 3 inch in the gun, Again, NO issue at all. The rubber plug fits firmly in my gun and takes a little effort to simply push out below using a thumb. I think these would be a good HD loads but since my gun has a 28 inch barrel it would be to clumsy to use it as a self defense weapon anyways. The shells shot great and recoil was noticeably less than the 2 3/4-3 inch shells as expected. Overall, I'll buy more of these to practice target shooting with and play around with. Since I don't hunt, Targets will be my goal.
