Yesterday I decided to load some rounds for my 30x47. The case is made by running a 300 Savage case into a die that pushes the shoulder back about ten thousands of an inch but leaves it the same over all length. I got the rifle CHEAP from an estate sale about 20 years ago. The fellow had died and had been a bench rest shooter and was a rifle crank. He liked to build rifles on oddball (to me) actions. This rifle is built on a tang safety Ruger 77. It is in the original wood stock glassed in. From the paperwork I found that came with it the barrel was the original Ruger bull barrel that had been a 220 Swift that had been sent to someone and they had re-bored and rifled with cut rifling and chambered for the 30x47 and ended up with a 24" barrel. The trigger on the rifle is a Canjar. From the paper work the fellow was going to use it to shoot cast bullets in hunter bench rest matches. He had just started working up his loads when he dies. This rifle will shoot bug holes with most anything you put into it.
I was going to load up some 155 gr Berger VLD (hunting) bullets. I already had some loaded and I just picked one out of the box to use to set my seating die to match the previous rounds. I have to use a 308 Win seating die. When I picked the round out of the box by grasping the bullet the bullet moved in the case. I could pull it out and stick it back in. I thought "somehow I had not sized the case because I do have a hand operated depriming homemade die that came with the rifle". I dumped the powder out in the scale pan and it was right on the money. I then full length sized the case in my sizing die. I reprimed and powdered and seated the bullet and it still could be removed easily by pulling on it. I checked every one of the other rounds and all were fine with no bullet movement. Was scratching my head on this one until I dumped the powder out of the case because it is a case full and tried to see if the bullet would push deeper into the case. BINGO found the problem. DOUGHNUT. Right at the neck and shoulder junction the neck was thicker than the rest of the neck and was not allowing the upper part of the neck to be sized properly and the seating depth of the bullet just happened to fall where the full diameter of the bullet was just above the doughnut. I have fooled with wildcats for over 30 years and this is the first time I have ever experienced the doughnut.
