That's right gun guys. Your favorite hollow point just became obsolete. Whether its Gold Dots or Rangers it looks like a new kid on the block might be worth checking out. I know I will. via Shooting Illustrated.
The initial goal of the EFMJ bullet was to provide a non-hollow-point projectile that would reliably expand without hydraulic dependence, yet would feed unfailingly in semi-automatic handguns. You see, conventional hollow-point handgun bullets need to impact a fluid-based material to expand. Bad guys are made of mostly water. As a conventional hollow point enters a bad guy, liquefied materials enter the hollow-point cavity and create pressure on the inside of the jacket walls. This forces the bullet to expand.Read the whole thing but I know I'll be taking these to the range as soon as I can lay hands on a box.
If the hollow-point cavity is clogged with some sort of material like cloth or dry wall, the bullet may not expand. EFMJ bullet expansion relies on mechanical force as opposed to hydraulic force. How does this work? The EFMJ bullet consists of a gilding-metal jacket surrounding a lead core located at the rear of the bullet. The open (rear) end of the jacket is crimped over the rear of the lead core, just like in a hardball round. The real difference is at the front of the bullet, where there is a void between the front of the lead core and the nose of the jacket.
EFMJ has been around for a long time. They actually don't perform as well as most modern JHP options. The reason they exist is that there are "less free" states like New Jersey that outlaw honest law-abiding citizens from possessing JHP ammunition, so this becomes the next best option.
ReplyDeletethey've been around a long time but they haven't worked as advertised. if you can develop a bullet that expands consistently reliably time after time with no loss in bullet weight then you're onto something grand.
ReplyDeletethats why i said hollow points were obsolete. i've seen them fail too many times for me to be entirely comfortable with them performing time after time. i'm currently running hornady critical defense in 9mm. i'm train with the idea of at least 4 shots per assailant. with the possibility of having to follow up on even that.
