XD45 7,124 Posted May 27, 2014 Report Share Posted May 27, 2014 Holey Bullets! Holey Bullshit is more like it. http://www.gizmag.com/compbullets-faster-with-vents/20806/ First of all, when the gun is fired, the vents supposedly allow the propellant gases to go through the sides of the bullet, providing lubrication between it and the inside of the gun's barrel. As the bullet exits the gun, the gases symmetrically shoot sideways out of the vents. This - so we're told - creates a "muzzle brake" effect. A muzzle brake is a device fitted to the end of a gun's barrel, that redirects the gases as they leave the gun, to offset the recoil effect. The vents in the CompBullets apparently serve the same purpose. At the same time, the gases shooting out of the vents are also said to create a rocket-like effect, increasing the bullet's velocity. All of you physicists are welcome to weigh in on this one, but it's hard to say if gases exiting the sides of a bullet would really cause it to travel any faster than gases that were limited to pushing on it from behind. Additionally, CompBullets are claimed to produce less muzzle flash and less smoke. If nothing else, all those holes probably make them lighter than regular bullets, to boot.

thebuns1 4,323 Posted May 27, 2014 Report Share Posted May 27, 2014 I don't know. Assuming that the gasses exit the holes evenly it may work, but id still want all the gas I can behind the bullet. Quote Link to post Share on other sites

ktcm7271 999 Posted May 27, 2014 Report Share Posted May 27, 2014 Energy = mass x velocity. Seems like removing the mass (all those pretty holes) would reduce energy. You would gain a short burst of velocity with the same energy (the powder charge) but it would slow quicker and hit a lot less harder.

gunfun 3,931 Posted May 28, 2014 Report Share Posted May 28, 2014 Come on it says "Rocket-Like Effect " They should man up and own it. It is a rocket effect, not "rocket-like" Those rockets just happen to be thrusting toward the center axis of rotation, not paralell to it. So Obviously they take pressure off of the back and vent it in a direction that does not thrust it forward. Therefore they cannot increase velocity. Cost of drilling holes precisely in a piece of moderately hard steel to make an effective muzzle brake good for thousands of rounds- cheap enough to sell profitably at $35. Cost of drilling holes in each bullet precisely enough not to destabilize it? I'm going to guess about the same per every bullet or two. 1 Quote Link to post Share on other sites

Seems like cnc machining bullets is all the rage: http://blog.rtba.co/3-reasons-dont-need-latest-g2-research-rip-cartridge/ Kinetic energy actually is mass times velocity squared (ek=mv2), so while a loss of mass will have a negative effect on the projectile's energy proportional to its magnitude, an increase in velocity will have a positive effect proportional to its magnitude squared. Your equation is for momentum (p=mv, where "p" is momentum), which is more likely to play a part in determining the bullet's maximum range. Bullets have been working fine for 100s of years.....when will they learn. Bullet designs have been advancing for hundreds of years. Not every step has been a step forward, but thanks to the proliferation of precision manufacturing technologies, more innovations can be made. Unfortunately, some new designs, like that bonesaw bullet that made the rounds on the web recently, are obviously not steps in the right direction, and manufacturers with limited budgets still have to try to offset their R&D investment by marketing their mooncalf products using hype-tastic advertising. This design does look like exactly that kind of nonsense. Actually, the first thing I thought of was an old Simpsons episode: Sort of ironic, really. 1 Quote Link to post Share on other sites

It is often applied to objects defined by feedback, surveillance and control tech. ^__^ Quote Link to post Share on other sites
