picked up some in the red low velocity exploding targets a couple weeks ago and finally got to try them out. they are awesome. they even pack more boom than tannerite. I tried the 3 oz. and the 1/2 lb. targets. there is a guy on youtube that uses them a lot, look under gy6vids.
i had some of the powder binary targets that come with the little red containers and they seem to make a bigger boom than the ten times larger ones with the granular component.
that and the smaller ones are for rimfire and the larger ones i bought at academy claim to require at least a .223.
Yeah, I've been using some called "kickass", even a subsonic .22 works.
I still buy Tannerite in the bulk form, but these are cool for those times you just want to take out the .22s.
