I found a few 600ct boxes cheap at a LGS and snagged them up. They shoot lights out in my 223 bolt gun. Better than the 80 ELD. 80 Amax are my go to in that gun. Good luck. Havent seen any in a while
I tried the eld when they came out and they don’t work in anything that the amax. I switched to the Berger 80.5 and never looked back. They shoot better than the amax ever did
