very good video!!
ive got a springfield made by remington serial number begining 404
yours is a 1943 not a 42 while the barrel stamped is a 44 its entirely within the possiblity of originality since yours was made in november/december of 43. its possible it got mated up with a 1944 barrel at the factory. even at that time they were producing recievers much faster than they could be barreled so there are a lot of correct matching recievers with barrel dates up to a year after the reciever was made. by that time of the war its highly unlikely yours or mine saw any combat and was likely issued to garrison troops in the states or used as a training rifle.

i find it to be a mild shooter with military 150grain and handload 168grain loads. recoil goes up just a scootch with heavier bullets. sound is about the same as any 30-06 hunting rifle. but im used to shooting 458 winmag rifles and 45-70
accuracy is phenomonal for a war gun. mine is easily sub moa out to 300yds with handloads. the action is butter smooth and i LOVE the magazine cutoff feature it makes single loading rounds while keeping a full magazine a very handy feature.
the clips for speed loading work awesome. the springfield 1903A3 is definately my favorite war rifle even above the garand. the thing i hate the most about the garand is the poorly designed rear sight. its clunky hard to adjust and can be easily knocked out of alignment. the only fault of the 1903A3 is the unprotected front sight blade as you said.
here is mine
i traded of a ruger SR556 for this one. best trade i ever made!!
