It was missing out of mine as well Jay. I can't see any difference in performance without it, both with the standard hop and the bgs hop.

Otto, .43g bb's are S**T! Better to use .36g and a lower powered gas. I've done a fair bit of testing with my K98 and .43's are too inconsistent past 50 metres. I've had confirmed hits at 100 metres with .36 bb's and predator gas.

Agreed. I use .36s, .43s are just too heavy. Pete I'd be interested to hear your findings from your K98 tests. I know you mentioned doing some a while back with various ammo & gas and with your tanaka vs your springer. Did you ever get around to do doing it properly?

I haven't done a definitive test of the Tanaka yet, the weather has been too cold for any accurate, consistent results. I did establish that the .36g available is more consistent, particularly at long range, than .43g currently out there. At the kind of ranges that .43g is ok, you're virtually in range of an aeg. What I really want to do is find out if I can get a gas to match the SGM Grandmaster .29g's that I have. I use them in my spring K98 and they are awesome bb's.

I'm referring to the "straight" .43g (graphite coated). For me, when I use a rifle, I want to get the maximum range and accuracy that I can against the superior firepower of the aeg's. As I said, the .43g is ok at 50 metres (or when it's really windy) and less but bear in mind most aeg's can shoot between 30 and 50 metres, so, where's the advantage for the single shot rifle? Now, if I can open fire at 100 metres, with a reasonable chance of hitting my mark, THAT is the advantage I'm after and I've found that .43's are utter crap for this purpose. With .36, I can hit 9/10 at 50 metres and probably in the region of 5/10 at 100m (ambient temperature and wind depending), plus, you can SEE the damn things and adjust fire if needed, very handy against moving targets.

But why use a lower powered gas with lighter bbs?

Surely you want the higher fps to compensate?

It doesn't work that way, especially when it's hot. I've tried green gas in the summer with .36g and, even then, they were curving upwards! (and also clocking well over 600fps!). If you use a lower powered gas (lower power does not mean low power), you can get a more stable flight. A bit like in a spring rifle, where sometimes using a lower spring actually improves performance. It's all about finding the perfect match of ammo to gas to hop setting, which is why I spend a lot of time testing guns on a range.

It's an airsoft urban myth that fps is the be all and end all for range and accuracy. A lighter bb doesn't need as much "oomph" behind it.

You should definitely NOT use green gas in the summer in a Tanaka K98! It can cause really nasty injuries at the illegal velocities it will result in. Even a heavy bb like a .36g will arc upwards with green in hot weather, this is why a lot of peeps use .43's.

It's trial and error for gas/bb weight. There are so many variables that have an effect, you really need to find out for yourself what works best for you. What I'm saying works for me (when it's warm enough!), is 134a gas and .36g bb's. Bear in mind that I have a BGS hop unit, bedded in with well over 1000 rounds through it, whereas a new gun, without any mods will yield different results and be nowhere near as consistent. I'm also totally obsessive about ammo and keep it religiously clean and examine every round as it goes into the magazine! I also clean my barrel at every oppurtunity. (Can't help myself, I was an army sniper!).

If I had to hazard a guess, I'd say try predator gas (or whatever the hell it is between green and 134a!) and .36 in the winter and see what happens. If it's got crap (ie, sub 350 with a .2g) fps, try green gas and see what happens. Then, it's a case of tinkering with hop settings, gas type and ammo weight to get the results you're after. At a game is not the time or place to be trying this.

I'm hoping to pick up a Tanaka K98 on Saturday via a swap at my local site - having read the past 3 pages I'm looking forward to experimenting with gas/BB's. Anyone know a good UK source of spare magazines? Cheers for all the hints on refinishing from you guys in the know too!

Firesupport are good for mags. Hardly ever out of stock and quick delivery.

LOL That goes to show it really is a personal choice of gun/gas/grade. I was using green and .25s at GZ last week and couldn't hit a barn door :D

Firesupport have had no magazines for a few weeks now.

The only place I've found selling them over here is Wolf Armouries, and they want £49.99 each. :shock:

It's a sting, but what are the delivery costs for FireSupport? I could take the tube to Camden and pick up a bunch of these for nothing if there's enough interest.

Funny that, because I ordered, and had delivered a new mag from them 3 weeks ago!

Finally got my Tanaka K98, quite well used and was fitted with a homemade sight mount system over the bolt (modified from a AK47 receiver cover fitted with a RIS rail!!!!!!) and held on with 3 extra screws through the woodwork - which I've removed and filled with wood filler - in the process of staining the dodgy bits now. I think the stock may have been lacquered at some point as it has a slight sheen to it, so I may completely sand it down and start again one day; colour wise its fairly light-I'm finding the light oak tinted satin varnish I'm using for the repair is nigh on perfect match for the existing finish so it'll do as is for now - I'm not fussed about having a "mint" looking one luckily!

It shoots dead straight at 40+m with green gas and .36's (410fps; cold day), also seems similar accuracy wise with 134a and .3's (though not chrono'd this combination yet).

As the foresight protector is missing and not having had much luck in the wanted section I've mocked one up out of brass tube and strip, next job is to reproduce it in slightly thicker metal and chemically blacken it.

As is it came with 2 mags, Tanaka sling, .36 and .43 BBs and the scope (modern) and mount bits (which will be used elsewhere) for a swap equivalent of £250 so I'm not complaining, not having had to fork out any cash! :good:

Re the above, has anyone attempted to fit a scope to the receiver (ie drilled and tapped holes and fitted a correct style set of mounts and a scope to it?) If so what parts did you use; were there any complications?

It IS possible to fit a scope mount to the Tanaka but not really worth doing because of a) The cost of such mounts, not to mention a "period" scope and b) The relative inaccuracy and inconsistency of the gun itself, particularly with some of the "heavyweight" ammo. It's fine as a normal "rifle" but not really consistent enough as a sniper weapon, which is why I never mounted a scope on mine.

By the way, chrono the gun with .2g bb's, not heavier ones. I'm not saying that this applies to you but a lot of people seem to think that it's ok to use any ammo weight, as long as the velocity is under 500fps, or to use heavy ammo to get past a chrono test, which, obviously, it most certainly is not.

You can get repro sight hoods from many sources, such as this one http://www.rytonarms.co.uk/shop/shop.php

Ok thanks for the link and info, quite happy with it in iron sight form but if I was to put a scope on it I'd prefer it on the receiver rather than the mount provided - but probably not worth it in terms of the upgrade parts/scope etc as you say.

Been a bit of debate re the use of .2g BB's for chrono testing on my regular site's forum recently - as you say some people don't realise this is the case until someone points it out.

We chrono all guns on 0.2s no matter what the owner say's ''he always uses'' this way all guns are allowed or failed :) I think this is standard practice on most sites.
