In General
Testing out the Underwood hard cast flat nose ammunition by Underwood in 10mm Auto and .357 Magnum. The 10mm Auto is a 220 gr bullet rated at 1,200 FPS and the .357 Magnum is a 180 gr bullet rated at 1,400 FPS. Going through the chronograph and giving a ballistic test to see how they do! Always appreciative of any channel help :) https://www.patreon.com/user?u=5828221
