Wait, is this a hybrid or something? where are you getting 580 psi from?(edit sorry somehow I misread fps as psi)
I doubt you're really getting 1500 yards; I have a gun about half that size that only does 250 or so.

Fnord, that's 580 FPS. It will shoot over a half mile before hitting the ground on a perfect day. NOthing is charging up before ignition, that is the chamber fan mixing the fuel and air. And I have already painted, just no pics yet.

1500m and a half mile ain't really the same thing.
About 700m difference I'd say.
I'd go with the half mile personally, a whole mile is a hell of a long way.

Wait, why did you repost it Karpa?
And the 1500 yards things doesn't hold a lot of water. Even half-a-mile is really too much.
With GGDT as my external ballistics program, using a muzzle velocity of 580 fps and a Cd of between .2-.3, launch angle configured for optimum considering the velocity and drag coefficient, I'm getting no more than 1500 FEET. That's 500 yards or so.

I didn't repost it. I'm just posting it in the showcase section of the forum since I just realized it existed.

MarkHFq: remember that GGDT does not take into account the fluid dynamics involved in the flying projectile. the golf ball has little divits that technically should give it a backspin, causing longer range. thats why golfers can hit the ball so far. its not because they hit it really hard, its because of the backspin.......... i can hit 250 yards without putting ANY power into the club (well some, but alot less than i can do)....
plus, 500 yards is quite a bit................. it takes me about 20 minutes or more to swim that far.........., and aobut 2:00 to row that far...........
