Well I may have said I would never be able to afford any Corbin stuff but I saved up and spent the whole $139 for one of his cannalure hand tools. A simple design and makes a nice crimp grove on a bullet. Nothing that could not be figured out on our own I'm sure. I must say it puts the finishing touch on the bullets made from cartridge brass. I'll get some pics up later.
So now a couple ?s for the many out there smarter then I. The crimp wheel has a high and low side either by design or accident. I'm sure the wheel it's self is a perfect round just the way it secures to the tool. Is this the way it should be? If I only made one rotation of the bullet there would be an uneven depth in the crimp grove. It does say to give the handel 3 rotations and as such the bullet will make even more rotations eventualy evening out the depth of the grove. Any thoughts?
Next ?, it is possible for me to increase the diameter of the bullet by a few thousands in the small area just around the crimp grove. How do I get around this. I could be just setting the depth to deep or ....... ? I did take a closer look at a few Hornady XTP .430 bullets I have and figured out they put the grove just ahead of the tangent or junction of the curve of the nose and the straight sides of the bullet. Back of grove measures .430 while front measures .425 allowing for the curve of the nose to continue from there. I guess it is like everything else in this hobby, tryle and error. But some thoughts from those of you out there on applying crimp groves would be helpful. Does the CH tool have a wheel with a high and low side design too? I suppose a call to Dave Corbin himself would probably answer most of my ?s but thought I would see what you guys have to say.
Thanks,
BT
