[QUOTE="Veteran, post: 2832623, member: 118038"] Well sending a man to the moon is above my pay grade too, but if you give me the right starting pressure, and the right friction profile for a hammer bullet, I bet I can model that in QL. The one thing that puzzles me about hammer bullets is te reported diminishing returns seen on bigger than .30 calibers. Apparently users have reported disproportionately less observed velocity increases on larger calibers than experienced below .30 caliber. The only thing this discussion has sparked is maybe on larger calibers, the sheer length of the bullet compared to smaller calibers implies it will always experience more friction loss because its mainly the front end of the bullet that is tapered and minimized as to bearing load in contact w the barrel. Maybe on smaller calibers, there is not so much length of bullet remaining behind the tapered point, and on larger calibers, there can still be a lot of surface area to travel down the barrel behind that tapered end? I dont know, Im just trying to rationalize why the data comes out different for large calibers? [/QUOTE]
