I'd say you're on the right track. Despite what some of the less informed will say, if you take an existing shape and make it heavier you will
dramatically increase the BC. And you won't need a special fast twist barrel. That said, most here would be more interested in a longer, more shapely bullet--like say, a similar size/shape to a 168 or even 180 Berger and it would offer more BC potential as well.
Stuff that shape with a heavier core and .8-.9 BC is easy, depending how heavy you make it. Once you get to a shape like that, making it longer doesn't do you any good. Making it heavier
I just hope you aren't reinventing the wheel here. There has been much work already in the area of making bullets with powdered tungsten cores: Corbin Bullet Swaging Metal Powders
. You can vary the terminal performance properties by mixing in other metals and chemicals, etc, but it's already being done. Don't reinvent the wheel, just bring it to us civilians. ;)
Anyway, good luck. I know I'd pay for a 30 Cal bullet the size/shape of a 210 but weighed about 280 when you're done with the 7mms. If you can put a tip on it that would just be icing on the cake.
