Here's something some of you may or may not have already seen . I'm attempting to contact all my Old friends in Low places an see if they'll allow me to play with them .

At the U.S. Army’s Aberdeen Proving Ground, a team of ballistics technicians, supported by some of the U.S. Army’s top sniper instructors, has been quietly developing a radical new “dimpled” bullet. The exterior of the bullet resembles the dimpled surface of a golf ball. The function of the special dimpled skin is to reduce projectile drag, providing a flatter long-range trajectory, and greater retained energy at the target.

In their pursuit of a lower-drag bullet, the Army tried a variety of designs, including bullets with circumferential drive bands, dual-radius ogives, and rebated boat-tails. The dimpled “golf-ball” design was considered a “long shot” according to the design team, but it has performed beyond all expectations. The nominal drag coefficient (Cd) has improved by about +.040, while cartridge muzzle velocity has increased by nearly 80+ fps because the bullet’s dimpled skin reduces in-barrel friction. What’s more — the terminal performance of the dimpled bullet has been “spectacular”. The Aberdeen team set out to produce a slightly more slippery bullet for U.S. Army snipers. What they ended up with is a bullet with dramatically enhanced long-range ballistics and superior killing power on “soft targets”.

Higher Velocities Achieved
There was a surprise benefit of the dimpled bullet design — higher muzzle velocities. Given the same powder charge, dimpled bullets exit the muzzle faster because they produce less in-barrel friction than do conventional bullets. This is because the recessed dimples effectively reduce the metal-on-metal bearing surface. Lt. Col. Eldrick revealed: “the added velocity was an unexpected bonus. With equal-pressure loads, dimpled .308 bullets will fly about 80 fps faster than normal .308 bullets. With the large .338-caliber projectiles, the difference is even greater… we can pick up nearly 150 fps.” Given the observed velocity gains achieved with dimpled bullets, Aberdeen designers are now working on dimpled shell casings for larger artillery projectiles.

I hate to be the bearer of bad news, but:

Would the sniper be required to yell FORE after pulling the trigger?

I was trying to figure out how they got it out of the swaging die. It looked to me like it would stick.

thank doc -- we got added to thier list of "fooled sites" ..

GREAT CALL

I heard that they work better in a reverse twist barrel because the back spin gives them greater lift.

I wouldn't use them because I have a slice.

I wanted to see if anyone was paying attention and SOME of you are !. Although that was a spoof perpetrated by another site ,I was curious as too how many of you had actually seen it . Dimpling could easily be accomplished if it were practical , however rifling and spin rates of projectiles aren't good for dimpled projectiles !!!.

I can tell you that the Below link ISN'T a Spoof see what Colt is up too .
