[QUOTE="STL_Shooter, post: 27136, member: 888"] Max, The PRL's have an extremely high BC because of the ratio of their weight (density) to physical size. The .308 253 PRL is, for instance, much shorter than a .308 250g lead bullet. That's precisely what makes them so desirable from a center of pressure/center of mass perspective. I think what Mach V was referring to with the airplane wing thing was those manufacturers that use less dense cores and thus have to make the projectile extremely long to get the weight up...
