.22 nato
[
The electric primer .22 NATO SALVO stuff was fired in the five barrel test fixture .
HISTORICAL SUMMARY OF ACTIVITIES:
1JAN53 - 30JUN53 - "Theoretical studies were continued on the Salvo Hand Rifle and preliminary drawings of a five barreled firing mechanisms were well advanced."
1JUL53 - 31DEC53 - "Final changes of design were incorporated in a five-barreled firing mechanism for the Salvo Hand Rifle. The Armory completed the design and detailing of a Caliber .22 five-barrel test fixture and started fabrication. Test firings were scheduled to determine many parameters, such as pattern control and cumulative reaction forces when firing in Salvo or in rapid sequence. Tandem bullet firing of two Caliber .30 bullets, using a rechambered BAR, showed promise....
The Winchester Repeating Arms Company made a study of a number of the reports listed in Ordnance Research Office Report T160 and made preliminary calculations and firings and firings to determine various factors listed in their contract. They conducted limited studies of the possibilities of tandem bullet firing using single and double-barreled rifles. A new proposal was obtained and a contract supplement initiated, whereby the facility would make an extensive investigation of this means of fulfilling the 'Salvo' requirements."
1JUL55 - 31DEC55 - "The conversion of models of the Caliber .30 T48 (FN) Rifles to fire the Caliber .22 (T65 Cartridge with Sierra projectile) was nearing completion. Schematic designs of barrel arrangements, bolt actions and feeding devices were explored and studied relative to a design of a three-barrel prototype weapon weighing approximately ten pounds and firing semiautomatic salvos with the Caliber .222 Remington cartridge. Fabrication of a three-barrel, vertical alignment test fixture to weigh approximately 10 pounds and fire semiautomatically three-barrel salvos on single shots to be used obtain information on handling and recoil effect upon the shooter was completed. Upon the Olin Mathieson Chemical Corporation (Salvo Contract) effort was applied to the following developments:
An erosion study of a Caliber .
The evaluation of relative hit probabilities of single-ball ammunition, and double-bullet cartridges was in process."
1JAN56 - 30JUN56 - "Twelve T48 (FN) rifles were rebarreled (chromium plated bores) and fitted with muzzle compensators. New firing pins with reduced diameter were provided and the bolt face bushed to correspond. These rifles together with a supply of modified magazines were shipped to Fort Benning for SALVO tests."
Double Barrel Rifle (Olin) - The basic design of a double barrel rifle using the FN type of bolt and carrier with top mounted gas expansion system was worked out. Much of the design and some detail drawings were completed and fabrication started. This rifle is designed to utilize a double-bullet Caliber .22 cartridge fired in semi-automatic salvos or as a full automatic weapon. It is amenable to change to other cartridge, bullet, and caliber combination."
1JUL56 - 31DEC56 - "The Multi-Barrel Rifle portion of Project Salvo was concluded with the exception of the double barrel rifle which was nearly ready for initial firing tests. A staff-study prepared in support of developing the single barrel high velocity rifle under Project Salvo was presented to Hq. Ordnance Weapons Command, and a mechanism study of such a weapon started."
For the Salvo Program, test and weapon barrels have been made in calibers from .125 to 7.62mm both smooth bore and rifled for experimental and engineering test use."
Ray you take GREAT photo's.
