They are basically one of the smoothest military actions next to the M1898 30 U.S. Army Krag bolt action.
I know that statement will get a lot of you guys fired up...try to hold down your Starbucks.
Here it is...The early M1903's(pre 800,000 serial number) had very smooth actions. As time progressed and mass production was required to meet military needs the quality deteriorated dramatically. The 03-A3 action with the late war bolt is brutal when compared to the early pre war guns.
It also seems that a lot of fellows prefer later era guns for shooting, yet the best of the breed are the early pre WW1 guns.
Why are they "expensive" comparatively? Looking at a combined production figure of over 3 million guns that is a logical question. The reputation the gun earned on the battlefield and on competitive shooting ranges are what drives the value.
The caliber it was designed for(30-06)is without doubt the most popular rifle caliber in modern history.
Yeah I know some you will spew your Tim Horton's double double all over your keyboard with that statement, but there is reality to that, due the volume of loading variations available. and the number of firearms manufactured in this caliber.
Let the debate begin anew.
