S&B ammo, especially the .223 you just bought, is decent ammo, and that's a very good price for it. Another brand you might want to consider in .223 is Fiocchi. Very good quality with very consistent performance and accuracy to match. I picked up some last year at a gun show and regretted I had not bought more of it at the time. When the next gun show came around, the dealer I bought it from was all sold out of it, with no more on the way.
