those are absolute junk. I don't think they are setting the molds right when the press them, causing them to lose there centrifugal spin down range (more metal off center causes them to stray off target).
I have shot both the PBA golds and PBA armor piercing silvers. They are not the most accurate but they hit hard and penetrate well, especially on tin cans say at 20 feet. The golds will sometimes pass right through the cans and only rock them, not knocking them over. The silvers definitely penetrate metal more than standard pellets. They appear to have a very small steel ball bearing in the nose. I have chronographed the golds in several rifles and you do get a big increase in velocity. With an Air Hawk it was 32% (more than 1200 fps muzzle velocity)over standard field pellets!! Yes, they are expensive and I wouldn't use them for everything but they definitely have a place in the ammo supply for my pellet rifles.
