Tiny projectile? hows the impact?
Also... 7mm doesn't even compare to a BMG 50.cal let alone a 14mm Mechem round. 7mm actually equates to just around 27.cal.
These Guns (the NTW-20 moreso than the Barrett) make extreme impacts.
People always assume that a small projectile cannot make a huge impact... but the design of the projectile, and the effect of impact have ALOT to do with its "Damage ability".
But also, spaceghost, as i said...the 7mm round versus the NTW-20 14mm would be small.... this also reverts back to my other point, the 14mm is (by default) twice the size as that 7mm rig you spoke off... yet it will do (much) more than twice the damage.
I'm not de-crediting that rifle that you speak of, but there are 1,000 different 7mm rifles out there.. i would have to know what exact gun you are speaking off.
BTW, fun interesting fact. the barrett Mag capacity is 5 rounds... the NTW-20 is 3 rounds
