I feel very fortunate to be the owner of this '03, it is an exceptional firearm...historically speaking. It consists of a 1930 four groove barrel, 1920 receiver. The rear sight assy, bolt, trigger and butt cap are all circa 1910. The firing pin is circa 1918/20 and remarkably, the wood stock is vintage 1906. It just amazes me that the bolt was retained for use during a 1930's armory rebuild. But it is the stock that is so amazing to have survived and the armory did not incorporate all of the modifications that a serviceable stock should have had at that time. So yes, I feel very fortunate to have it. And the guys at Williams Gun Sight, Inc did an outstanding job with reparkerizing all the metal work (without loosing any of those little springs/pins/screws I sent them). I would attach some pictures but I am unable to figure out the process. My questions: I've not yet fired this but will soon. All those rear sight apertures confuse me! I want to begin shooting at 100 and 200 yards and later, reaching out further. What apertures do I use for 100/200 yards? The safety lever causes me some confusion too. When the bolt is 'cocked', I must still pull the firing pin back by hand about .100 of an inch in order to engage the safety. Is this normal for an '03? It just seems to me that the safety should be able to engage at any time after the bolt is cocked. Gentlemen...any thoughts?
