I took my newest 300 Blackout build out for a test run and to get the scope sighted in. I always run the cheap Remington ammo (120 gr OTFB) through for the first time and to get on paper. The rifle performed flawlessly, and 19 of the 20 rounds were a non-issue. However, when I pulled the trigger on that one round, it was loud as hell and kicked like a 308. I noticed that the bolt didn’t close all the way following that round, so I dropped the mag and cleared the chamber to see what had gone wrong. To my surprise, the primer from the previous round was lodged in the feed ramps. I then searched for the case, which showed signs of high pressure. I inspected all of the cases fired prior to that one and they all checked out just fine. After inspecting the rifle, all was fine with it as well. I then finished the mag with no more issues. Upon checking my target, the bad round hit about 9 inches higher than all the others. That’s a big change at 100 yards!
I am thinking this had to be an over charge from the factory. Maybe a double charge, but can’t imagine the case having the capacity to hold 30+ grains of powder. Has anyone else ever experienced something like this from a factory round?
