O3A3 anyone?

Mike, this bbl slugged at .311. Using the fatter 180 gr projectiles, a starting load of IMR 4831, and no signs of high pressure in the fired cases,we got the accuracy anyone should get from an Enfield modified as this one was.

I had read something this in an old American Rifleman,and took the gun to a smith I trusted.

Here is just a little history from the Book of Rifles.

NOTE: The 30-06 is a slightly-modified version of the original 1903 cartridge, which was loaded with a 220gr round nosed bullet at a muzzle velocity of 2300 fps. A change was made in 1906 changing the bullet to 150gr and the case shortned by .07", with an increased velocity of 2700 fps. The 30-06 can be chambered and fired in any rifle made for the 1903 round, however, the opposite is not always true.

As indicated in the "Other Names" category the initial Springfield round was designated 30-03 Springfield, and with the modification in 1906 the designation changed to Ball cartridge, caliber 30, Model 1906. As with most all military regalia, the name was shortened to 30-06.

Also located in the other names section, the round was called the .30 Government. The original .30 cartridge was designated the 1903 cartridge, the year it originated. The modified round was designated the 1906 ctg., the year it was modified, with the modified name of 30-06. The first two digits, 30, indicating the caliber of the cartridge, the 2nd two digits, 06, indicating the year of modification.

This designation was necessary as they were limited in the firing of both cartridges as one should not be interchanged with the other in the same rifle. The -03 produced very poor accuracy in the -06.

The Pedersen Device should also be mentioned with the 1903/06 rifle. This device quickly changed the 1903/1906 Springfield Rifle into a semi-automatic rifle. During WWI it was decided that the most venerable period for the infantry soldier was while he was crossing "No-Man's
Land", that strip of land between the allied trenches and the German trenches, during attack. Bolt action rifles just did not have the capability to fire rapid enough for "Walking Fire" as it was called.

The United States decided that if each man was issued a semi-automatic rifle he could use suppressive fire as he crossed the "No-Man's Land", to keep the Germans heads down during the assault. They also realized, (U.S.) that there was also the need for the bolt action rifle as well and the possibility of arming every soldier with a semi-auto rifle was out of the question at that time.

This dilemma was solved by John Pedersen, who was working for Remington at the time. He devised a method of removing the bolt from the M1903 Springfield rifle and replacing with a simple blow-back device fitted with its own magazine and a short barrel which,resembled a .30 M1906 cartridge case. This was fitted into the chamber of the rifle, after the bolt was removed, with the magazine protruding out the right side, where the bolt use to be. With this device the soldier could convert his bolt action rifle to a semi-automatic rifle in about 15 seconds. The
cartridge was specially designed by Pederson to suit the modification. The cartridge resembles the lengthened .32ACP cartridge in appearance.

The Pederson device was short lived due to the adoption of the M1 Garand rifle.

Harley, I have a Mark 1. I've never seen a bolt or magazine for the Pedersen setup. I thought the magazine fed from the left? What's the slot for?

Art
 
It's an angled slot (about 45 degrees from horizontal), long axis parallel to the bolt, on the left side of the receiver. I always read this was where the magazine fed through.

I will have to research. There is apossibility that I might should have said left instead of right for the feeding on the Pederson device.

Art:
The only photo I have is not very clear, however, it appears that the magazine is inserted on the right. The description it states, "The rifle has a slot milled into the receiver that acts as an ejection port."

As there was a milled slot, (ejection Port) on the right for the standard bolt action I would presume that the added milled slot would be on the left, indicating that the Pederson Device fed from the right, ejected left.

I'll check further, I think I have a better photo around here somewhere. Be patient.

Jim Keenan:
Can you enlighten us?

Found the photo. The Pederson Device did feed from the right, and the slot on the left is the ejection port.
