Ended up finding some on sale pretty cheap using ammoseek.com and bought a bunch of shells.
Here's what I found out
There's some inconsistencies in targets and aiming, I was figuring out different ways to do it as I went. This is the first time I've really patterned (or shot, for that matter) shotguns
Barnes pellets circled in black
As a comparison, Federal LE132
Federal LE 133
This 25 yard was my first target and I should've out on the green circle to show reference of POA and POI.
I strongly dislike the Hornady Critical defense, it kicks very hard and has a hell of a flash. All shooting done at an indoor 25 yard range.
