[QUOTE="MontanaRifleman, post: 836312, member: 11717"] I think to "get it right" the first time, you'll need a ballistic engineer/ballistician and even then, coming up with something new that works right the first time is a long shot. I get the feeling Berger went through a lot of R&D/trial and error to come with their hybrids.... especially with the 300 gr 338. I would think you would want a similar design as the hybrid. Not sure if a bullet shape can be patented but if it is then you have to come up with something similar but different. If you could insert a tungsten core into the tail and shank of a ULD bullet that had an expandable lead core nose, you could increase the sectional density of in the same shape and increase weight and BC of a particular shaped bullet. I.e., if you took the shape of a 308 215 hybrid, which requires a 10" twist, and put a tungsten core in it and increase the weight to say 225 gr, you could theoretically stabilize that bullet in an 11" twist. The bullet CG would change which might require a slight modification of the shape. Likewise you could do the same with the 230 gr which is the heaviest of that shape that can be stabilized in a 10" twist. A denser core would enable you to offer a bullet with higher weight/SD and BC in a 10" twist. On top of that, the tungsten core would make an excellent terminal projectile. Something to think about... When you open the "start a new thread" option, there should be an option for a poll at the bottom. [/QUOTE]
