FX Airguns Cracking Heads

This is a video about my FX Crown and FX Impact taking the California Ground Squirrel at various ranges. I tried to make all head shots, hence the nam FX Airguns cracking heads. In the Crown, I am shooting Varmint Knocker XLHP lugs at 1010 FPS and in the Impact, I am shooting NSA HP slugs at 955 FPS. The crown is sporting an MTC Viper PRO FFP 530x50 and the Impact is sporting an Element Helix 624x50.
