Okay here they are. Barrel is a Krieger No. 17 contour finished at 30" from the face of the receiver, muzzle diameter is exactly 0.930". This was built by Greg Tannel of Gre-Tan Rifles in...Rifle Colorado.
Cartridge with the barrel info. 0.340" neck and the case turned 0.337" loaded. That is a Berger 210 VLD at 2.933" base to ogive. The recoil lug off to the right is 0.350" thick, I don't think it will flex at all.
This shows the bolt bushings installed on the bolt. You almost cannot see them but they're about 0.002-0.003" tall so when the bolt is closed it has zero clearance in the raceway locking the bolt up tight so no flex to the bolt.
Greg opened the front receiver to allow better loading of cartridges.
This is his work on the rear bridge.
The business end. Perfect.
Here is that same shell loaded in the magazine. There is actually room in front of the bullet. I will polish the feedramp until it looks like it is chrome plated. Not because I need to, but because it will help make the shells feed slicker'n lizard poop on a hot brass pole.
There she is. And no, I have not weighed her yet since I did not remember to buy a set of swivels for the thing!
