177 JSB Knockout Slugs A look at the new 177 slug from JSB

A look at the new .177 JSB Knockout slugs. I chronograph the rifle and put the slug through some clay before going to the range to test the accuracy in the video that will follow this one. The slugs come in tins of 400 for an approximate cost of £10 per tin excluding delivery. The slug on test weighs grains and have a BC of 0.066. JS Ramsbottom: Airgun 101:
