green gas in the k98

[worldwardrew]

just to make sure, but it is safe to use green gas in the tanaka k98, right? I mean it won't cause any damage to the gun after long term use? Some one told me to only use hfc134a, I find it hard to believe that the gun cannot handle green gas.

[stealthomega]

Its not the fact that it can't handle it. You will just be shooting over 500 fps from what I read. I have not chronoed mine on propane so I don't know the exact number. But where I live that would make it classifed as a real firearm shooting that hot.

[worldwardrew]

Well, the guys I play with don't care. The power the k98 has adds to the whole experiance, it makes game play much more dynamic. Alot of us have scars from some skirmishes lol.

[2nd Bat]

Exit wounds aren't that much fun but the Tanaka can handle Green gas just fine. The FPS on a warm day probably well over 550 FPS so the gun is quite hot. If used in a sniper roll with minimum engagement range of say 50-75 feet you're probably just fine. Airsoft guns loose alot of inertia in fairly short distances. Inside of 50 feet the Tanaka is nasty. They are a very hard shooting accurate gun.

Ive heard complaints of instability on green gas, difference of 60 fps sometimes, but My chrono only goes up to 400 so I cant test mine

I've taken mine up to red gas (which i suppose isnt really a BIG improvement over green) and it has been chronoed in an air conditioned room (about 65 degrees) at 595 FPS with .2's. So yeah this thing can tolerate a lot, however I dont use .2's in it, only .43's since it gives you the best accuracy. I also only allow myself an engagement distance of 100 feet for safety reasons.

[2nd Bat]

That sounds like a good call from a maturity and responsibility perspective. Here's a tip! Chrono all weights in all guns. Long barreled gas rifles sometimes generate higher FPS with heavier BBs then lighter Bbs. I know that defies logic but what happens is the initial FPS within the barrel is slower with the heavier BB creating more gas energy behind the BB prior to it's departure from the muzzle. Hence once it reaches the muzzle the additional energy propels the BB faster. Don't believe me? Test it out. This is not true of all guns or all BB weights. My Marushin gas Garand shoots quite a bit better (FPS) with the .45 gram BBs then the .34. I thought it might have been uniform shape or perhaps size of the BB (tighter fit) but that wasn't it. It was apparently the weight and slower initial acceleration. Also in many cases even with a slower intial FPS at the muzzle the heavier BBs often travel further! Check your FPS at the muzzle with various weight Bbs and then test the FPS at 30 feet away from the muzzle. You'll be amazed at the results. The lighter weight BBs lose FPS very quickly where the heavier ones don't. The result is heavier BBs that have a slower intial FPS often exceed the lighter BBs at 30 feet distance.

[sabrepilot9000]

It's true. I thought I was using a messed up chrono the first time i tried my Mauser, but i was getting something like 460 with .3's and 488 with .43's. Weird, but it make sense when you think about the physics. Plus when you use heavier bb's you get the intimidating whizzing noise that your targets get to hear. I love that sound...

[CharleyNovember]

I shoot .43's out of my APS/K98 and people refer to it as me shooting bricks at them...scares the mess out of them so I understand. ;D

[sabrepilot9000]

I love it, its great. Specially when you can just point your rifle and they run, no waste of ammo, lol. Plus when your shooting that hard and heavy its great to take em straight through the bushes they're hiding in then listen to them "He shot through the bush?!". Great fun.

[worldwardrew]

Are the .43s the metal coated BBs?

[CharleyNovember]

yes mine are. Sounds more ominous than it really is though. It is just a fine coating that happens to come off in my barrel a little at a time I have to clean my barrel often, between missions for example.

[2nd Bat]

A technicality but worth mentioning is that in some state metal coated ammo is considered illegal for action pursuit type games. It was a way around the whole BB gun issue in states where BB gun wars were not allowed. (Airsoft is okay!)

[CharleyNovember]

well considering that is my only option with the APS fixed hopup i'll just keep on keeping on.

[mikkel]

Are you using Straigth .43 ?

Its not a metal coating, but graphite (don't know if this is the word for it).

[sabrepilot9000]

Yeah, I use the Straight .43's, I get the best accuracy/FPS combo with those. Those are actually solid graphite. Every weight below that is graphite coated. There are also .88 Carbon Steel BB's that you can get from 6mmshop.com. That would be crazy.

[worldwardrew]

I bought some .43s today, so about how many rounds can you shoot before you have to clean it due to the graphit comming off in the barrel? Some times our games go on for a few hours with out a break.

[CharleyNovember]

graphite yes you are correct my mistake. I dunno we play like 1hr 1.5 hr missions then I clean my barrel.

[worldwardrew]

do you use green gas or 134a, and are there any heavy weight plastic BBs. I'd hate to clean the thing after every game!

[worldwardrew]

the straight .36 ammo looks plastic

[sabrepilot9000]

You know honestly, I havent cleaned my barrel in a while and it seems like my accuracy has increased slightly. Not a whole lot, but enough that you kinda notice it. Im not sure if the graphite in there is tightening up the space in the barrel or what, but i dont think itll make a huge difference if you go a game or two without cleaning the barrel. Just my 2 cents, maybe I've hit a fluke thats not normal or something.

[worldwardrew]

Ok thanks for the info man.

[2ndranger]

So if this is my first tanaka G33 mountaineer g-version kar 98, what gas should I buy how much should I buy to last a day event?

2ndranger

[2nd Bat]

Personal taste and what your opponents will allow. Most would probably let you shoot green gas if you're responsible about engagement ranges. A can should easily last you a couple active days worth of shooting since the Tanaka is bolt actioned (probably more) If you're play field restricts FPS for all rifles to 400 FPS or less with .20 gram which is fairly common you'll need to go with 134. If however they allow 550 FPS for sniper rifles (The Tanaka will qualify)

Do take note that the warmer out it is the hotter the gun will shoot. (more expansion for the gas.)

[2ndranger]

should I go with the green gas or not and how many canisters should I buy for a day game???

[rbx6jm7man]

you'd be safe with using one can for a small game. 2 cans for a large op.

[2nd Bat]

One cautionary note about Greengas is be sure to not store it in your vehicle where it is exposed to direct sunlight (Through a window for example) It is capable of exploding quite violently. We had a player who left a cannister in the bed of his truck inside his canopy top. It literally peeled open the aluminum canopy like a sardine can and blew out his windows. This in the NW where it wasn't that hot. (maybe in the 80s!)

[rbx6jm7man]

oh yes! don't leave green gas in your car. it's very dangerous. if you're outdoors, i'd recommend you find a safe and nice shady place to put it.

[2ndranger]

Wow this makes me more confident on buying green gas ,LOL.

[2nd Bat]

Probablems with exploding Greengas are extremely rare and nothing that anyone should be overly concerned about beyond awareness and the subsequent reasonable caution. Just keep in the shade (when stored for a long time) and away from open flame at all times.
