I have an interesting "what if" situation. What if in the late 1890's, upon the US military realising that the Krag rifle was obsolete, we kept the 30-40 round and simply added a spitzer bullet and increased the pressure slightly for more velocity bringing it up to 30-06 power. Then chambered this upgraded 30-40 (Lets call it the 30-40 M2 for simplicity.) in the new 1903 Springfield rifle. Now with the stage set, how would US military small arms development have been different. I have my ideas on what would have happened, based mainly on the British being "stuck" with the 303 round as well as the Russians. I want to hear you're ideas as to what happens. Please don't let this turn into a caliber debate.
