As a final test to confirm the results I got in ballistic gel regarding expansion or lack there of the FX Hybrid .25 cal. slugs I shot into a dead pigeon. My ballistic gel testing did not show any expansion or mushrooming of these slugs so the next step was to affirm my testing. I will say I have watched a few videos on YouTube hyping these slug for being very explosive and fragmenting but the testing in my opinion was flawed. I have made my mind up on the performance of these slugs regarding expansion you can make yours. Bill
