Just A Normal Guy In The #330 With Interests

I love the way people will make art out of anything.

Also, these are beautiful.

It’s usually loaded with a hand-crafted low-drag 1,690 grain solid copper bullet, which it fires at roughly 3,350 fps. The projectile itself is roughly 4 inches long, with driving bands and an aggressive rebated boat tail to reduce base drag.

The sectional density is around 0.70, which is an astoundingly high measure of the mass-to-diameter ratio. It’s very heavy for it’s caliber, nearly a quarter pound.

The ballistic coefficient is about 1.85, which is an astoundingly high measure of how aerodynamic the bullet is during flight.

Here’s one unfired bullet next to a recovered bullet:

At the previously stated muzzle velocity, the bullet is carrying about 42,000 ft-lbs of kinetic energy. It remains supersonic out to 5,000 meters, or 5,400 yards.

For comparison, a similar monolithic bullet in .50 BMG usually maxes out around 800 grains at 2,900 fps. It has a sectional density around 0.44, a ballistic coefficient around 1.13, and it’s carrying less than 15,000 ft-lbs of energy at the muzzle.

For further comparison, you’d be hard pressed to find a 5.56 load recipe that hits 1,400 ft-lbs.

Here’s a comparison image of the three examples: one 14.9mm, one .50, and a stripper clip of green tip 5.56 NATO. The 14.9 is coated in black molybdenum disulfide film, which acts as a lubricant and helps extend barrel life.

Needless to say, the rifle that fires this colossal cartridge is appropriately huge. Currently, the test gun is a single-shot bolt action, which wears a 48-inch super-heavyweight bull barrel. The entire gun weighs in at about 100lbs, due to deliberately added weight.

This weight helps dampen recoil to a survivable level, although the designers suggest that a recoil-reducing stock, giant muzzle brake, and lighter barrel profile could bring the weight down to 30 lbs without inflicting enough blunt force trauma to kill the shooter.
