Anyone used this ammunition yet?I ,there are claims it might make the .17 redundant as it uses the standard .22 rifle.
CCI Copper is 22lr and travels roughly 1800fps while most .17hmr is 2300+fps so you'll have a flatter trajectory over a longer range. Unlikely it will make .17hmr redundant because it isn't the same.. Even hyper-velocity 22lr doesn't come close to that speed.
