The exact performance of .50 BMG, like all rounds, will vary depending on the rifle and bullet mass, but between 11,000 - 12,000 ft-lbs and 2700-3100 fps would be a reasonable range for guesses.Hailfire753 wrote:D@mb... that is exactly what I would have guessed, but I did not want to say it for fear of over-guessing. This is AWESOME!

Ever heard of a CLGG? It's essentially a high mix hybrid burning a light gas like hydrogen or methane that's being researched for long range shooting (one of them is able to hit a 5 metre square target at 100 miles apparently). They've currently got them over 4km/s, well past what a powder burning gun can achieve. Other than the higher muzzle speeds that can be achieved though, there's really no advantage of gas mixes over powders, and I imagine that the CLGGs must be running at the equivalent of several hundred x to produce the results that they do.Makes you wonder why the military doesn't pick up on this kind of deal, if only for launching practice shells. You would think that it would be cheaper than powder.
Funny thing is, I only held that record for a few days. Larda was testing it at 40x oxy/propane just about a week after my first 20x shots. I believe it'll be a while before anyone else reaches these kinds of mixes, but it's nice to see that spudguns are beginning to approach the energy density of conventional firearms (surpassing it in some cases, as most shotguns and pistols don't reach the chamber pressure that this thing does).It was only the other month we were excited about DYI's 20x cannon.
oh my god. That is f***ing awesome I think we found someone to build DYI's DDT gun...
Speaking of which, anyone know whats up with the PD?ramses wrote:
And there I was *thinking* that *maybe* I would hold the muzzle energy record, at least until the pipe dream gets built. :crybaby: :crybaby: :crybaby:
I hope you can find some depleated uranium somewhere.
BTW, what is the bore size?

Yeah but the double edged sword is if these things started becoming more common place, governments would start noticing and would most assuredly ban them, or at best, require them to be licensed. As jaw droppingly awesome as this is, I see it note worthy only as an academic exercise and not one that should be or needs to be repeated very often by "spud gunners".DYI wrote: but it's nice to see that spudguns are beginning to approach the energy density of conventional firearms (surpassing it in some cases, as most shotguns and pistols don't reach the chamber pressure that this thing does).
Dang...this thing is impressive...and no one has mentioned the really cool gas recoil system.And what's this...SpudFarm wrote:when i have one more look at this gun i really consider to become gay
