Oh god, I've thought of this years ago but recently the thought came back to me. Dood.. To the parent of the thread, you'd be on MY TEAM.
My thought was with paintball guns or airguns myself. Having done some researching into airguns recently and reading up the past posts above some airguns do have some very flat trajectory with the smaller calibers. FYI, I'm not talking that old Daisy Red Ryder here as everyone thinks of when I mention airguns. I'm talking airguns that can shoot 1000-1600 FPS in .177/4.5mm, .22/5.5mm, or heck big bore it with .308/7.62mm and higher cal airguns.
