This video reviews DoubleTap's 10mm 155-grain copper expander ammunition through ballistic gel testing. The presenter, an experienced firearms instructor, found the ammunition to be underpowered for the 10mm caliber, despite good expansion and penetration. While deemed adequate for self-defense, it doesn't meet the 'hot-loaded' expectations for 10mm.

In ballistic gel, it demonstrated good expansion up to 0.815 inches and penetrated 14.25 inches, retaining its 155-grain weight. However, the presenter deems it underpowered for the 10mm caliber.
