This ballistic test compares .45 ACP and 9mm ammunition performance. The .45 ACP Corbon Powerball (165 grain) created a larger wound cavity and significant tissue displacement in gelatin compared to the 9mm Barnes XPD (115 grain) fired from a Sig P320. While the 9mm penetrated slightly further, the .45 ACP demonstrated more immediate tissue damage. The test highlights the trade-offs between penetration and wound channel size, with the .45 ACP showing a greater potential for immediate incapacitation due to its larger cavitation effect.
