Hey Green Frog.
That was my from the ground up 200 yard cast bullet deer hunting rifle. It's a 45-70 case necked down to hold lots of lube grooves. Wanted the right amount of case volume for my purposes and 45-70 worked out just right. After it was all said and done turned out that what I'd invented amounted to a smokeless version of the 9.5 Mauser. Those in the picture were loaded with the Lyman #375296 (283 grains), a compressed charge of 760 and CCI-250 primers, 2153FPS, what I used in '91. The point of the design was to get a heavy soft bullet moving fast enough without pressures subjecting the base to plastic deformation that would destroy its accuracy. Bullet design compatible to those ends was critical. When I designed the cartridge in the early 80's the conventional wisdom was to cast hard and use fast burning powders. Experimented with cartridges until I figured out how to make this work, selected the diameter and weight I needed, chose the parent case for volume and neck length. Got the reamer and dies. Don't mind telling you I was way proud when it all came together.
Oh, forgot to answer your question about the wood. That's all from the No.3. The brother's skilled eye and hands at work.
