In your expeience are these brass any good for accuracy or should I buy some good brass, and which brass would you recommend in 223 rem.

I was shooting 1/4" with LC brass. Although, not having to remove the primer crmp maybe well worth the money to buy Winchester brass.

It is very shootable brass if one wants too take the prep time. I stopped using Mil brass because of the time it takes to remove the primer crimp.

The brass I used was factory remanufactured and shot once out of my buddy'g gun, he doesn't reload so he gave me the brass. When reloaded they remove the primer crimp at the factory.
