My son went to an outdoorsman retreat a week ago and spent the majority of his time at the range. He let everybody shoot his Rock River Predator Pursuit. There was an ammo vendor on sight who had everything .223/5.56. The Rock River digested everything they fed it except the round that is still stuck in the chamber. It is a loaded round that would not fully chamber. I'm pretty sure that the brutes leaned pretty hard on the forward assist in attempt to get that round all the way in the chamber. Then when that wouldn't work they used a block of wood and a hammer to drive the bolt back open taking a piece of the case rim with it. My son tried to push the round out with a ram rod to no avail. Then he brought the gun to me. It is obvious that the bullet on the stuck round has been pushed back into the case and most likely flattened to some extent. I poured some 3 in1 oil down the bore and let it soak for a couple of days just to make sure that the powder and primer were rendered inert. Then I poured a good copper solvent down the bore about every 4 or 5 hours until the full bottle was now empty. I then drilled a quarter inch hole in a 1x4 and centered the hole over the bore. My aluminum ramrod went through the hole in the board and down the bore of the rifle. When it came to a stop there was only about 1 inch of ramrod sticking up through the board and that was plenty as the case would surely be free if the ram rod went south even a portion of that inch. I started off slow with some love taps and nothing happened. I increased the strike until it was mushrooming the ramrod. I ruined that ramrod so got a second aluminum ramrod out and cut it off at about the same length as the first. This time I gave it one hard(real hard) whack with my 20 ounce framing hammer. I hit it perfectly square and once again just mushroomed the ramrod on both ends. That at least tells me that I am against something solid inside the case. I was barely able to pull the ramrod back out because of the mushroomed end. That last hard whack did knock the primer out of the case. I am going to pick up 1 each brass and stainless steel ramrods today(the cheaper variety). I have a couple of real nice brass ramrods with swivel handles but they were $50 a piece so will look for a cheaper one to sacrifice.
Do you fellas suppose that the chamber will be ruined by the time I get that case out? I can't imagine the why of it. Did somebody get moisture on that round and then drop it in the sand and then load it anyway? Did the round before it have headspacing issues and in the end extract only the back half of the case then this stuck case was wedged inside the front half of the last one fired????
Guys I have been doing this a long time and have never had one stuck in the chamber like this, however when you visit the black gun forums it seems to be more common than I would have suspected. Wish me luck!
