PHEW! you guys don't know how worried I was when i collected my spent casings and saw this!
I have waited 2 and a half months for my new saiga 7.62 to arrive from backorder. got it yesterday, shot it today, saw this, jaw dropped, got really pissed, went to my ffl, showed him the casings, said it looks like either a headspacing issue, overreamed chamber, printed out the phone number for RAA and said let me know what they have to say about it. I was like #$%#^%$... boy am I really really relieved. Thank You Saiga-12.com, you have saved me from yet another headache!
