Ford:

I have corresponded w/ Mr. William Noody and he gives that 6mm/ 0.243" can be used to make longer jackets and that the walls are a bit thicker. Of course it is possible to use the 0.224" bullets to upsize if he had too. He is designing the bullet to hold together up to 4000 ft/s if it is pushed that fast. He has ordered 6mm jackets from Corbins to complete the project for the 5,6mm X 61R bullets of 79 or 80 grains. He somehow polishes the bullets to get the target weight.

Hochachtungsvoll,

Raimey
