Fosgate Posted October 20, 2015 Posted October 20, 2015 This guys builds the worlds first hand held rail gun with a 3d printer. https://www.yahoo.com/tech/s/3d-printing-used-first-real-handheld-railgun-fires-134325053.html?soc_src=social-sh&soc_trk=fb
Jones Posted October 20, 2015 Posted October 20, 2015 It's not really a rail gun it fires at only 560 mph that's the speed of a comercial airliner. A hand gun fires 3x faster.
Fuzz Posted October 20, 2015 Posted October 20, 2015 I disagree. A railgun is an electrically powered electromagnetic projectile launcher. The speed of the projectile is irrelevant, except in its effectiveness as a weapon.
btp1979 Posted October 20, 2015 Posted October 20, 2015 My math could be off, but that equates to around 820 fps (feet per second). That's pretty close to what 45 ball flies out at. I sure as hell wouldn't stand in front of it. As for a handgun going 3 times faster......not so much. It's pretty cool though!
skalls Posted October 20, 2015 Posted October 20, 2015 Depends on the handgun round. Hot 357 sig round move closer to 1400 fps. 9mm can push 1300s. Big bore revolvers, 454 casull, 460, and 500 s&w can get stupid fast. And technically are handguns/portable cannons
TCContender Posted October 20, 2015 Posted October 20, 2015 I have a 6.5 JDJ barrel for my Thompson Center Contender that will spit a 120 gr Nosler BT downrange at over 2500 FPS, but only Ron Jeremy could carry that pistol concealed. As for the homemade rail gun, you know that there is a nanny state hand-wringer somewhere looking for a way to classify this as an "assault rifle". Good thing he opted for white PVC and no bayonet lug.

I sure as hell wouldn't stand in front of it. As for a handgun going 3 times faster......not so much. It's pretty cool though! A five seven is a normal size hand gun that shoots over 2300 fps. My original point was just that the article makes it seem like something it's not. Although technically a rail gun it fire very slow compared to the mach 6 rail gun the navy has.
MrGTO Posted October 20, 2015 Posted October 20, 2015 I didn't read anything in that article making it seem like something it's not... I'm sure if he had an unlimited budget he could do much better but comparing a kid with a 3D printer to the Navy railgun system is a little silly.
