I have heard of these rounds several years ago in some rag. I suppose they come in 9, 40 and 45. Does anyone know if they live up to the hype? and to all the reloading gods out there, how would a .40 bullet like this perform at full-house 10mm loadings? I'm no reloader, but say I came across a few boxes of this, could I somehow extract these to load into 10mm? Just wanting to know just how safe my Glock 20 can keep my family.
