They worked fine for me. I prefer them over the discount shells loaded in Spain but I can't give a solid reason why I prefer them. I do like Estates a little better than Centurion just because they are not imported.
I haven't used their shotshells but I had to inspect each round of their 5.56 I bought to weed out the rounds with the dented / gouged cases. There were more rejects than I wanted to see. I quit buying them.
You still get what you pay for.. From the 16..just about anything will work..As the yardage gets longer..a faster shell.. and harder shot will always prove superior.. For practice..I'd shoot them.. if I did not reload.. but a regestered match.. I'll stick with Remington/Winchester/Federal
