Same bullet, just loaded as 223 and put into nickel cases which helps distinguish them from the practice rounds. Both are SAAMI spec, just one to 223 spec and one to 5.56 spec.

And, in my experience, the 223 load is consistently better shooting. The 5.56 loads always seem to add a bit to group size. The LE223T3 seems to be a consistent 1.5-2moa load at 100yds through any of the guns I’ve tried it in. The 5.56 gives me 2.5-3.5 moa at 100yds. This is fine for minute-of-felon, but not quite what I like to see. My personal rifles are 1:7, maybe a 1:8 would be better, but I don’t know.

I use the 223T3 loads personally and at my department.
