That was me, on Sunday morning. I had to meet a good friend on a local range, right after work, so I went to the firing line with having been up since 2PM the previous day. That wasn't the smartest thing I've ever done.
So, I set up TUB out at 200 yards like last time, this time I was going to have fun with the 527M carbine....yeah right! I think I hit the steel maybe 2 out of ten on average, and had several dead primers. No, good solid primer strikes, nothing wrong with the rifle, but primers that just refused to ignite. Remington 9.5s, if you want to know, never had a lick f trouble with them, ever. But that day, I had 4 of them fail on me out of one bag of reloads. Not happy. Also chewed the support 2/4 for TUB so badly it was left behind for firewood.
Yeah, that wasn't that great. Still beat the dogsnot out of being at work, though.
