Things I liked: I expected a bit of hype and placebo, and there may be a bit, but the results are clear on the targets. These shiny little baubles tend to go where you point them with minimal wandering. Distictly different than the dimpled copperheads I've used for decades thinking BBs is BBs. Kind of odd when things actually go "PLINK" when plinking instead of thunking the backstop. They are trackable at night reflecting in the tactical flashlight beam. Things I would have changed: If precision grinding does this,I might be inclined to change to a highly polished variety for the same reason. Then since BBs aren't all the same after all, a brand that duplicates the golf ball dimples or baseball stitches might have ballistic advantages, and clearly weight variations belong in this market like it is for pellets. Has anyone ever actually fired the mythical "GOLDEN BB" of lore? (not dipped coated or plated) What others should know: I don't do chrony so fps is relative thing for me. Attention here folks, I may be self deluded here as well but be sure of your downrange and backstop and wear the eyewear. Reflected bounces seem to show uncharacteristic vigor, I heard multiple ricocheted rebounds not the usual 2 or three. Don't know if it was faster or maintained its energy better or both.
