I am so angry I could spit. My 308 Ruger American won't chamber a factory 308 round. It would seem as though they installed a short chambered barrel and never got around to finish reaming the chamber. Ruger QC seems to be non-existent at this point. I just got my Single Seven back from having it repaired. Last year I had to send in my New Vaquero. Right now Ruger is batting .400 with me. 3 of the last five Rugers that I have purchased have been defective. This one takes the cake.
