I happen to enjoy all types of firearms. From single shot to machine gun. From civilian to military and caliber does not matter. Generally I like to chat about projects we are working on or building small arms, but this series of posts are going to be about the Winchester self loading rifle. The first post will deal with the Model 1903 self loader and its successors the Winchester model 63 and the Taurus copy of the model 63.
When the Winchester model 1903 first came out 22lr ammunition was not of the same quality as 22 ammo is today. In fact a large portion of it still used black powder as its propellant. Therefore to insure a rifle that would work properly and not gum up due to the residue that black powder leaves behind a new cartridge was developed. This cartridge was the 22 Winchester automatic. This round fired a 45 grain lubricated lead bullet with a muzzle velocity of 1055 fps and a muzzle energy of 111 ft-lbs.
The picture above shows the difference between the two cartridges.
This rifle used a tubular magazine. The clip as we know today was not developed unit 1919. Loading ammunition while shooting all three of the rifles was easily accomplished, but care had to be taken to insure that the round were dropped in properly.
The production of the model 1903 rifle ended in 1932 with Winchester making a little over 120,00 units.
By 1932 22 ammunition improved in quality enough that the rifle was re-design for this caliber and the model designation was changer to model 63. All together approximately 175,000 were made and sold.
However, now the butt stock was more into the design of a semi-auto rifle and checkered.
