The projectile is a hornaday .430 265 grain fix it went thru a 70 kilo pig side on thru the ribs at around 60 yards. The projectile was recovered in a stump about 15 feet behind it. As I said launch speed over 2,400 fps. The rifle was my 444 launch platform an SMLE number 4 rebarreled and modified for the 444. A real easy conversion that is stronger than the the Marlin lever action.
