Tanaka k98 power

Or perhaps it was freezing cold!

Just noticed the strange colour of that BB. And the lack of redness around the injured skin - I would have thought that would be a red and throbbing conk!
Heh, Che hit the nail on the head - a soft nose. Sponge-like.

I think the suggestion of 'first bb out' is very contentious and has hitherto been unnoticed - which is very odd wouldn't you think?
Dodgy chronoing due to gas as has been suggested and seems plausible.
As for 'a cauterising bb' - well, that defies any rational explanation.

I'd suggest proper research results are needed before causing alarm, something scientific and repeatable - plainly something is wrong, somewhere!

Incidentally, BBs embedded in soft tissue isn't that unusual - cheeks, forehead and now nose! Dammit, someone (I can't remember who still has one in their hand!).

Perhaps the moral is using paintball masks that have apertures small enough for a BB to penetrate (or are not airsoft specific) do NOT provide full face protection.

and neck dont forget our summerset friend

Hmmm. I have an idea forming. Bit of a WW2airsoft forums research project!

Quite simple really. How many on here have access to a Tanaka K98, a Chrono and a thermometer (plus 134a and propane/green gas)? - if so, drop me a PM.

PS - this comes from someone who has *still* got a BB in his hand (Digicon TCC + CO2 + boredom, if you *really* want to know )

Lack of redness and the slight brown was the iodine spray that was administered within mins. Good point about paintball masks not being suitable for airsoft protection. I wasnt aware of other BBs being enbedded in players, and this one worried me. The guy was really good natured about it, I think I felt worse for allowing it to happen on my watch
Edit strange colour of bb, it was I believe a blaster .36, but I may be wrong.

Aye, we are all with you on the concern front...

Or we could shoot people at ever decreasing distance to see how close you have to be to get a bb to imbed itself. Any volunteers
but on a more serious note we all go into the game with our eyes open and well protected .so just like that fellow you just have to take it on the chin.or nose

My concern is that we would all chrono the guns at the beginning of the day when they're all freshly loaded and tickedy boo, all reading sub 500 and everyone believing they are using a safe gun, when potentially on the last game they could be loading a mag that has the potential to be hot.
I was disqualified from a UKHFT national event a few years ago. I started the day with an Air Arms s200 which we chronod at 11.93 ftlbs. perfect using barraccuda match pellets. As usual I got collared to cook lunch, so left my rifle in the store for safe keeping. It was a hot day!
I went out and shot an ok half round including my best ever upwards vertical shot ( Lie at base of tree shooting upwards into the canopy to simulate the hit on a squirrel, very hard to work out trajectory!) I went on to the chrono check and as my rifle was in the sun all day crept over the limit to 12,03 ftlbs which made it an illegal fire arm. Disqualified instantly.
I did threaten to stick it up the guy's ass from Air Arms, who were sponsoring the event, but was held back and told it wasnt good for the image of the range!
What I'm trying to say if this can happen in a £400 air rifle it can happen in a Tanaka mag, and if it does then it's worth knowing about!

Hmmm. although I am no authority on airsoft gas guns, over the years I have had quite a lot of experience using propane.

From my experience the most common pressure for Propane is in the region of 60 to 70 PSI, this is formed by the gas bubble on the top of the LPG in the bottle, this however is affected by abient and direct heat, on a sunny day with bottles left in full sun I have got 120+ PSI out of a 47Kg bottle! So (sorry for the egg sucking lesson) when cold, the gas is reluctant to come out of liquid form and when hot it is really wants to, hence the increase in pressure.

As for "first round" too hot theory, if the mag is very full and liquid gas is released behind the bb then this will continue to "gas" behind the bb as it travels down the barrel, this would increase the bbs acceleration and therefore give a higher muzzle velocity, the longer the barrel (ie rifle) the more time it has to accelerate, the better the seals (hop and bb/bore) then the better the effect would be...

Just a thought!-- attachment is not available --

Probably the only way to know for sure if it truly is the BB or the gas messing it up would be frame-counting on high-speed camera footage.

That sounds like a theory worth testing.

Actually this is crying out to be made into an episode of CSI what with ballistic gel and whatnot. Bagsie be the moody ginger fella.

do we get to hire a bunch of Hummer H2's ?

Who pays for the fuel

Don't need fuel - we'll just modify a couple of 1000bhp K98s to blast us to where we want to go

Tanaka jet-pack mod?

Mythbusters is more like it...

These pistols are WA 1911 I think and both are fully uprated. (I dont know the in's and out of then) They nomally fire at 400 450fps on 143A and will run on Green gas with no problems.

A 1911 running 400-450 FPS ?!?! That's way beyond "hot".
I suppose your site doesn't chrono pistols...

I suppose your site doesn't chrono pistols...

Many sites don't. Hence the reason you see so many of the multicrap/systema boys toting Tanaka M500 revolvers as sidearms, capable of over 450fps on green.

hey I had a systema! :p

Interesting debacle though, one for the boffins methinks!

The gas theory on 1 bb, I can almost agree with (note almost) but it wouldn't occur with mag changes as the pressure from the gas is thus minimised after that first shot.

Getting it upto 1000fps, well I honestly think theres some feck up with the chrono-ing.

To be totally scientific about it all, you would also have to run comparative tests with similar weapons or any testing would be null and void. Ie you would need several (more comparsions the better the result interpretation is. You would also then need to use several types including brands of gas, not to mention several brands and weights of bb. Next you'd need to test at several distances to conform to comparative testing means. From this point then you'd need to measure the velocity, chronos of a variety brands, power inputs etc as well as some other means of testing the projectile speed of a bb. Theres an ISO method on velocity of projectiles, thus I bet theres an appropriate one out there on the net if someones bored and wants to google that could be used for experimentation to get the most accurate results. That would show the correct international standard works for scientific means and experimentation. Anyways only after all that could you legitamitely confirm K98s are bad, at which point I guess you'd find several other toys are too and we're all far better sitting and having virtual airsoft games from the safety of behind your keyboard (watch out for getting your fingers pinched in the keys though )

Sadly I only have access to agar and I think work would notice if I started to half inch it would be fun though making it double possibly triple strength to get the ballistic turgidity factor right.

Anyways Kermit has fessed a non K98 bb implantation, I would be curious to know if injuries of embedded bb's have ever occured with other airsoft implements? Not being an open dayer, I've no idea if such has happened, but I'd be suprised if it had not occured at some point, I'd also expect some random accident from the most "unexpected" implement. I'd then be curious if it had happened on the conditions, distance, gas, bb, etc etc

By now no you've all fallen asleep .......

Kermit, my Tanaka G33 with bgs hop and green gas at about 24 degrees celsius was doing about 580fps with 0.2g bbs, measured on two separate chrono's. I didn't experience any "first bb" effect in my testing, but to be fair hadn't left the magazines out in the sun to warm up.

I have since sold it (didn't want to use a hot gun and didn't want to nerf it with rubbish gas) so unfortunately can't take part in your experiment, but it would be an interesting exercise.

If anyone is going to test their's, be sure to have a consistent time between each shot to allow the mag to recover from cooling each time.
