8mm BBs

[my_plague_666]

8mm is really just cool because its bigger.  they hit harder because they have plenty of mass, but thats aboutit.

...buy teflon coated 6mm ones. ive seen 6mm bbs that are heavier than 8mm and still cheaper, and far more convenient as they are almost univeraly compatible.

curse 8mm

[Bengali]

Resurrecting an old thread, how many sites in the UK are allowing 8mm guns these days? I have been out of the airsoft scene for awhile...

<{POST_SNAPBACK}>

 

as far as im aware non yet though i could have missed one.

 

if someone brought along an 8mm garand say to a site and was allowed to use it i think a lot of people might be cheesed off. i think the reason they arent used over here as much as america is because of the lower power laws so it keeps everyone comparable

[Richard Wynne]

Sorry, I saw this thread:

 

http://www.arniesairsoft.co.uk/forums/inde...opic=85660&st=0

 

And got the impression that perhaps 8mm guns were becoming more acceptable to the UK airsofting community. Must admit my curiousity is due to an interest in using a 8mm gun.

[Catman]

Well as we're posting on a thread that's over two years old ....

 

 

If your site limit is 328fps (1 joule) with 0.2g you should be able to use 8mm gun as long as it chronos in at:

- 0.27g = 282fps

- 0.34g = 250fps

- 0.45g = 218fps

 

If you're 8mm gun is single shot (which most are) and your site rules at 500fps with 0.2g 6mm for single shot then your 8mm gun would have to chrono in at:

- 0.27g = 430fps

- 0.34g = 383fps

- 0.45g = 333fps

 

(the FPS results shown here the joule values are what you'd get from a 6mm 0.2g)

 

Of course check with the people who run your site, they might tell you to f-off or have their own limits.

[Richard Wynne]

Thanks for the figures. Guess I will have to play it by ear, from site to site. Atleast now I have some data to use to try to convince folks that 8mm does not really make much difference if the velocity is not too high.

[Thorbard]

Since limits are energy limits, not velocity limits then there is no reason not to allow 8mm BBs. I certainly dont see why they "should be illegal".

 

As far as accuracy goes, a .35g 8mm will be MORE effected by wind than a .35 6mm at the same power.

[mauserfreak]

Does anyone know where to get 27g 8mm ? Can't find them

[Rob15]

they should all be illegal in the uk ... so why bother?

<{POST_SNAPBACK}>

I don't see why they should.

 

The majority of Marushins 8mm guns are NBB or bolt action (except the M2 and MP40 when its released) and are not subject to the 1.35j limit on self-loaders.

 

Ontop of that on 134a the fps is generally low enough to make them 1j or less.

 

They have more energy because they shoot heavier 8mm bbs at the same FPSes as lighter 6mm bb GBBs. How are they even legal in the UK?

<{POST_SNAPBACK}>

As above, they're 1j or less or not subject to the 1.35j limit.

 

 

Also, i have played against 8mm M1s and KAR89s (and been hit by them) so there are UK sites that do allow them.

[Nic @ Airsoftworldwide]

I personally think all airsoft revolvers should be chambered for 8mm. (Its more realisitic since they have less range but impact with greater force)

<{POST_SNAPBACK}>

 

Computer games lied to me... THEY LIED!

 

Agreed though

<{POST_SNAPBACK}>

 

...first of all tell that to the S&W M500!

 

second...basicly you want all revolvers to be impossibly expensive to skirmish practicaly. and they only impact with greater force if the BB is traveling faster, you cant have over 1j anyway you'd only be able to have a bulkier, more expensive, easier seen BB traveling slower than a 6mm one so that it can hit at 1J

<{POST_SNAPBACK}>

That's not strictly true, is it?

 

A revolver (or my NBB Bren Ten for that matter) is not semi automatic so, legally, it is allowed to fire at anything up to 9J muzzle energy. There's nothing in law to prevent this.

 

Because the 8mm BB has a larger surface area than a 6mm one it spreads the force of impact over a larger area. If ballistic tests were carried out on 8mm BBs they would be forced to conclude that 8mm BBs could be fired safely at higher velocities than 6mm ones.

[balberoth-the-destroyer]

I'd also like to point out that if you're using 0.27g 8mm at 1J (282fps) which you would have to if you were using it as a normal skirmish gun, not a sniper rifle with a min engagement distance, you would probably expect range similar to a 0.25g 6mm, yes?

 

NO!

 

The 8mm BB has a larger surface area, and considering that you'll have to use close to the same weight as a 6mm, at the same output velocity, the 8mm will not fire as far, because the larger area makes the drag force that it incurs when travelling through the air higher, meaning that it'll begin at the same energy state as a 6mm, but will lose energy more quickly due to drag, hence limiting your effective range.

It will also be more vulnerable to wind, as the larger surface area affects in the same way, more area for the wind to push on.

 

Based on those facts, I don't think that they are viable in the UK, because you literally lose performance compared to a 6mm.

 

(edit: minor typo)

[Xaccers]

Basic example, take a sheet of paper, screw it up into a loose ball.

Throw it, not how far it went.

Screw it up into a tighter ball, throw it with the same force as before.

It goes further right?

...yeah but you cant skirmish at 9J

 

thats the point i was making

[Dist]

just a note to the ppl complaining of the price, a 6mm bb has a volume of 113.1mm^3 where as an 8mm bb has 268.1mm^3, this means that a 8mm bb, although only 2mm bigger, takes 2.37 times as much material to manufacture as a 6mm bb, so if a bag of 1000 8mm bbs cost the same as a bag of 2370 6mm bbs of the same weight, then that ofcourse is normal.

[Sledge]

Um... explaining why 8mm bbs are more expensive doesn't make them any less expensive. They're still expensive and annoying.

i aggree with sledge here.

 

but i guess what youre saying is: you get what you pay for...more volume... and therefore BBs with lower skirmishable velocities, that are easier to dodge and more affected by wind.

 

besides, it has little to do with ammount of materials, those costs are negligable. as far as i know 6mm Vs 8mm was like betamax Vs VCR, only unlike betamax 8mm doesnt seem to have accepted total defeat and as it is a less used calliber there is less demand and therefore manufacturers will sell for more to make up for lack of popularity.

[Sledge]

The real problem with 8mm is that every so often a genuinely desirable gun (blowback Automag, blowback Mauser) is release ONLY in 8mm, so Marushin can prolong the life of this dying calibre.

 

[my_plague_666]

yeah sledge, but then still hardly anyone buys these desireable guns because theyre 8mm which just makes people hate 8mm even more.

 

i recon if marushin went over to 6mm they would make so much more profits

[evilliboba]

They thing is, they could make a lot more money making a desired 6mm gun. That way more people would buy it and not be put off by 8mms.

 

I personally have nothing against 8mm BBs. I used them in my M500 to evil CQB effect.

 

I did get shot in the bare finger once with a .45g one going 350FPS at 10 feet... You should have heard all of the four letter words that magically flew out of my mouth.

 

Edit: Post sniped.

<{POST_SNAPBACK}>

 

my point is, they are more expensive because your getting more. its stupid to complain about the price when you are getting what you pay for, you arnt getting ripped of compared to 6mm bbs, and you also require less 8mm bbs so who knows, maybe it works out cheaper because you dont spray bbs everywhere like you would with a 6mm AEG.

 

I thnk 8mm would be more popular if it was simple to change between 8mm and 6mm, but since you cant just change the barrel to chamber the gun for a different size round like you can do with real steel wepaons, there is a much more limited ammount of weapons that can use 8mm, and thats how itll stay unless they invent soem way to easily switch a gun between 8mm and 6mm

[my_plague_666]

<{POST_SNAPBACK}>

 

yes you are

 

nearly £10 for a bag of 500 8mm, while £7 for 3500 6mm (very high quality ones at that)

 

how is that price jump proportianal to the mateial used?? theyre just over priced and by paying extra you're buying BBs that dont even perform as well (skirmishable velocity, wind resistance, visibility)

[Sledge]

The only thing I can think of it would make sense to use these stupid rounds for would be sniper rifles. Then the cost wouldn't matter so much, because you are trying for one shot one kill, and the fact you need higher power to make them useful wouldn't matter.

i just checked WGC and looked at the 8mm bbs sold there and compared them to 6mm bbs of as close as possible weight (which were the straight brand). The heavyweight 6mm bbs cost a little over double the cost of the 8mm bbs for twice the ammount, that means 2 bags of 8mm bbs of similar weight to the straight bbs will be cheaper and yet the same ammount of rounds.

 

The bbs around .36g work out slightly cheaper shot for shot with the straight brand, but the 8mm bbs are only slightly more expensive.

 

It all depends on what brand of bbs your comparing them to. straight make decent quality 6mm bbs that i used to use in my sniper rifle a lot, and yet the per bb price is about the same as 8mm bbs of the same weight, and since 8mm bbs are bigger yet cost the same in this case, your getting more for your money then with 6mm bbs.

 

In the end though i think 8mm bbs are rather silly, the only thing i like about them is that if AEGs started to adopt 8mm bbs instead of 6mm, the capacity of high caps would be more sensible, instead of many hundreds of bbs per mag, there could be less then 100, would imo is more sensible then a single high cap lasting a whole game and not needing to reload.

[Bodgeups]

For those of you who might still be interested in this thread, RSOV are now selling bags of 1500 ACM 8mm bb's for £7. Weight is 0.48g, so hopefully they will bring out some lighter ones in the future.

 

If I still had my 8mm M500 mossberg I would have bought some straight away. Alas, I found a 6mm version and stuck with that
