I wish I saw this video review someone did on youtube before I bought these.[...]If the link doesn't work, search youtube for "snap caps best & worst"I didn't even open the package, going to resell locally since it will cost me about 1/2 as much as they cost, to ship them back.Went to MidwayUSA.com and bought the Tipton snap caps. I don't want to dig out aluminum shavings from my gun, as the above video shows these A-Zooms will do.
