Need Headstamp ID
Got a handful of range brass mixed in with some of my R-P .223 I shot a week or so a go.
Headstamp reads: 5.56 . . C B C . . 1.4 The CBC could be GBG, GBC, or CBG; my eyes ain't what they once were. Anyone know what it is and if I should reload it or toss it? |

All the CBC brass I've come across is boxer primed.
Since it's marked "5.56" it's likely mil-spec and you'll need to ream or swage the primer pocket to get rid of the crimp.

As noted above: MagTech.
CBC/MagTech brass is generally half decent in handguns, but I haven't worked with it much in rifle cartridges. Keep an eye on flash hole diameter, primer pockets, and "feel" in the sizing die, to avoid any potential issues.
