Winchester Silvertip .357 Magnum VS .40 S&W Ballistic Test

Testing out the Winchester Silvertip in .357 Magnum and .40 S&W. The .357 Magnum is a 145 gr STHP and the .40 S&W is a 155 gr STHP. I do a ballistic gel test with and without 1/4" medium density fiberboard to represent ribs or sternum. Always appreciative of any channel help :) www.patreon.co...
