    Starting at 1:24 in this video the guy says that they used "high velocity rounds traveling just under a mile per second". The gun looks like an M14 or variant... Wikipedia says ~2800 ft/sec for the M14 and many .308 applications :hsugh:

    I saw someone post about a varmint cartridge that went 4000 ft/second but even that still isn't "just under a mile per second", however I'm betting this is just typical "exaggerate where it will make people want to watch" television bullshit.

  2. The Ruger .204 breaks 4,000 fps. The .223 WSSM can break 4,000 easily too. There are also a few wildcats that do it, but they're rather uncommon.

    9/10 things that any news outlet says about guns or gun laws are total bullshit.

    None that I know of.

    That's obviously 5,280fps..... a waaaay lofty goal for any bullet to even stay together at. Might have been some rediculous wildcat that would have pushed it..... think like 378 weatherby or so necked down to a .224 projectile. Barrel life would likely be in the lower hundreds of rounds, and you would likely nuke most bullets light enough to reach that speed.

    Holy shit, didn't even notice this over on reloadersNest:

    http://www.reloadersnest.com/detail.asp?CaliberID=100&LoadID=1147

    2fps shy, out of a 22-243 Middlestead. Wouldn't have thought a 308 case would have had enough capacity. Using 30gr Barnes varmint grenades (more proof that Barnes, is indeed, the shit).

    Still only a 153 power factor :mamoru:

    To the best of my knowledge the fastest commercial production round was .204 ruger at ~4200 fps.

    A friend of mine that owns a machine shop used to do alot of experimenting and claims to have necked a 30-06 shell down to .17, and that the bullet was destroyed before it even left the barrel. Though he does tend to tell alot of BS stories so you can take that however you want.

    That's plausible to me. Hardcore wildcatters are a strange bunch, and will do shit just to prove that they can.

    Nuking a bullet in flight is no thang. Push lightweight cup/core varmint bullets really really fast and it will happen more often than not.

    I'm pretty sure the one I saw posted about before was a 22-xxx (or some other 2 digit combination followed by another 2 or 3 digit combination)... maybe the 22-243 as mentioned earlier in this thread.
     
  10. .22-250 maybe? It can be loaded to over 4,000.

    ReloadersNest is showing the second fastest load they have being a 22-250AI @ 5130fps.

    There is no factory cartridge that is going to take you to that speed. In this realm, most of these cartridges are pretty niche items (though I do know a guy with a 22-250AI, and would love to build one myself). Dies will be expensive (and sometimes completely custom), reamers are hard to find, and barrels will be eaten quickly.

    TV does not accurately portray firearms, anymore than it does anything else.

    Shit, I can't even imagine any vest being bad ass enough to take a .224 solid traveling >5000fps; that would absolutely be hell on anything.

    I believe I've seen some commercial .22-250 rounds loaded to a claimed 4,250fps. Not too far off, but tagging the 5,000fps mark does have a nice ring to it.

    .22-250 + 36gr Varmint Grenade + 5,000fps + Prairie dog = Unmeasurable win

    I remember when I was taking our "riflery" class here at school, the teacher had some handload 22-250 rounds. The were loaded pretty hot I guess as only about half of the rounds would make it more than 10 feet without bursting into a ball of dust

    120mm APFSDS rounds used in tanks travel faster than a mile a second.

    No rifling and a loooooong barrel kind of helps... although I guess that it's fewer "calibers" long than the average 20" rifle barrel.
