i don't have an answer to that.. i am not privy to why. maybe you should ask them.. i was not trying to project that the intent was for "your" barrel.. i would presume that that would for a test barrel that they use.. who knows. i was just relating something that i read in a article, so there you go..But how would they know you barrel will produce the same velocities? and why 1073, their goal is to produce ammo that will shoot best in a wide range of rifles & pistols, interesting if this is true.
I think I am going to ask Daniel at Lapua I will post what he says.
