Tony Gettel is doing the stocks. I have used his stuff before with great results. I was looking at charcoal as well. I think it would look good with the SS.
I haven't made a firm decision on the brake yet. I do have a carbide sizing die for the .450. This Dillon was actually set up for commercial production of .450 ammo.
I can just run it at a relaxed gate and still run 400-500 per hour. I have it set up to do a two step crimp.
