This is fascinating, thank you Hangtight so many variables there, more than Real Steels in fact. One for the General Airsoft folder, phew, I should have paid more attention to the physics master at school!
But basically a normal site limit of about 1 joule might get a .30 or heavier out to up to 60-70 yards?
Whatever else I need to get a chromo, then I need to pay some real attention to matching hop up to BB weight as I get the impression that those foremost factors in airsoft range.
I still wonder if a longer barrel would the best way of launching .30s or heavier up to 100m?
And I can't think of a better use of space than a bullpup, that and the fact that if I get something like an AUG then i can easily whip the barrel off and change hops myself.
But am longer so sure about the DMR thing, from what I'm reading here I get the impression that fps, like long barrel length is not one of those foremost factors.
That being so, it comes down to: What is the optimum barrel length for the UK site limit of 330fps? And what is the optimum BB weight and hop for that?
