                                                 Interesting Rifle Test

An interesting test of the new Krag Jorgensen rifle has been made recently at the United States engineer ground at Willets Point. In order to determine the penetrative power of the gun a number of pine boards were fastened together till a thickness of fifty inches was obtained. Two of the shots fired at this target at short range passed entirely through it and none of the bullets fired penetrated less than three feet. The same test tried with oak planks also gave highly gratifying results, the penetration in this case being thirty-two inches. Iron plates two thirds of an inch thick were also pierced. A very curious result was obtained by firing a bullet at a series of thin iron plates placed an inch apart. The bullet was found to pass through one plate after another till it melted.
