Excerpt from Annual Report of the Secretary of War for the Year 1880, Vol. 3 of 4 This experiment shows that with pressures entirely within the limits of safety the increased velocity due to chambering has increased the power of the 8 - inch rifle about one-third, and that the increase of power is accompanied by an increased accuracy of fire. The wear of bore incident to the higher charge with the 111 rounds fired seems no greater than that in the unchambered gun with the 35-pound charge. The system of chambering in all future conversions or new construe tions is recommended. The battering charge of the ordinary S-inch rifle is only 35 lbs. Powder and 180 lbs. Shot. By chambering, we are enabled to increase the powder charge from 35 to 55 lbs. Its penetration at yards will be inches, the ordinary rifle giving only inches. The 9-inch English rifle gives inches, so that by the use of the chamber the energy of the 8-inch has been increased beyond that of the next higher caliber, English - a most satisfactory result.
