We will be controlling the weight of the core material. At this time I cannot say exactly what the specific gravity will be. That will be a function of the materials we have to use to achieve proper mushrooming, adhesion to the jacket, and specific gravity of the matrix materials. Theoretically we could achieve about 75% increase in weight on the same profile with current art- but don't hold your breathe for anything like that. This has to be a bullet that works on game as well as on the range. Cost of a 200 grain bullet on a 125 grain profile would also be prohibitive.
