    Hollow Point Boat Tail?

    Hey guys I got a question: Why is match ammo always hollow point? I mean it would seem that full metal jacket would be the answer seeing how it doesn't change shape while flying through the air. So if you guys wouldn't mind, can you explaing why hollow points are more accurate than standarad full metal jacket. And please, don't go all physics on me.

    HP or not to HP

    Without going all PHYSICS on you, the HP sets up a CONE of forced air that the Bullet travels inside of, adding somewhat to the selfstableizing of the rotation.

    The same principle is used for golf balls and dimples. It is to create a small area of turbulence which helps to stabilize it. Has anyone ever tried a bullet with dimples along the bullet to see what would happen?

    Well, to be honest about it all, the hollow-tip (different from a hollow point which is made to expand when hitting a target) is a bi-product of building an accurate and precise bullet. Sierra started doing it years ago building their matchking bullets because it creates a more uniform bullet. The tiny tip is where the wire holds the lead core and then the copper jacket is wrapped from the base up to the tip (this is backwards from normal bullet production). When the manufacturing process is done, the small wire is pulled free leaving a tiny tip. It "so happens" that the little tip creates a "bubble" or "cone" that does not HURT ballistics, but it does not aide either, its a slight misconception.

    Now, since match ammo is all about accuracy, you use the best bullets, which are manufactured this way (sierra is not the only one that does this, and to be honest, I'm not positive if they were the first). And so that is why match ammo nearly always has a hollow tip.

    Everything MEL said... Also... when you dont have a lead base ... the very hot gas's and fire from the gunpowder does not contact any lead... thus ... keeping lead out of the barrel.
