Norma .223 in 69gr and 77gr
Pappabear got some factory Norma .223 to play with. The first thing that struck me was how short the 69 gr ammo was.
I didn't measure OAL because we were out shooting and I don't have dial calipers out there. But here's the ammo next to a 2.25" standard length hand load:
The 69s shot really well in the Geissele Super duty. My first 3 shot are on the left, then I blew is and shot the other two on the right.
The 77s shot MOA with a lot of horizontal if I remember right. BOTH loads gave us bolt over failures in two different suppressed ARs. A 10.5 LMT and the Geissele super duty. No chrono data this trip.
I'll pull down the two bolt overs and post the powder type and charge. Both bullets are mashed into the cartridge.
