I went ahead today and tested the .25 cal. 31.5 grain Varmint Knockers I had bought recently. They did damn good for expansion on both the 20% five pound block of Clear Ballistics Gel and amazingly just as well on the 12 oz. block of 10% gel. The first part of the video is getting the velocity readings of the Varmint Knocker and using my pvc dampener to get the harmonics on the slug exiting the barrel/liner for accuracy. Bill
