I hope you are right!!! I will probably call it the .450 DGW for dangerous Game weapon, sort of like the .366 DGW which I developed on the .416 Rigby case. I am trying to get it ligitimised which is a long process. At present it is in Cartridges of the World (Tenth edition page 201) and Quality Cartridge is making brass and loaded ammo for it, Midway sells the brass also. I hope I will have as goor results with the .450.
At present the reamer is on the way and I have done some playing with cases. I can dump in 67 grains of 3031 and fill the case to the bace of the shoulder, this would not be a compressed load however 69 grains of that powder in the .458 winchester with a 500 grain bullet is. The reamer I have comming is in reality a .300WSM reamer that Dave Manson of Loon lake Tools is fitting for removable pilots. I will cut the chamber using this reamer and use a .458 Winchester reamer to cut the throat. This will give me room enough to seat even the heavy bullets out far enough so you do not loose any case capisity. I have high hopes that this cartridge will equal the .458, you should only need 20to 22 inches of barrel and a standard length and some short actions will give you plenty of mag length. I will try to keep you guys informed as work progresses.
