Testing BBs

After we spoke about the G&Gs PSBP on Sunday I bought a bag of .28s, happy to donate to the cause.

Cheers

A press does apply a measurable pressure but does not simulate a shock only a drop weight will do that

Very true point mate it’s impact that’s the impotant test for me too , you carefully stand on a glass bottle nothing happens , you drop the same bottle it shatters ?

edit 

Oops ! Forgot to say thanks for putting all that donkey work in to the testing , yes not ‘laboratory conditions’ but quite frankly I’d trust your findings over a retailers or a paid test ! ?

Yes and no the boost is fast push akin to a slam so similar but yeah not 100% the same. 

But you can say at what force a bb shatters to a reasonably precise point. 

If doing a shooting test then the gun needs to locked into position so it is always hitting exactly the same point and angle otherwise the angle it impacts can vary results.

Are you doing some tests on mesh as that would be the main one to see. Which bbs shatter small enough to go through as that is definitely the biggest issue. The mesh being a thinner edge could give completely different results to a plate and would be good to compare.

 
I am sure any tests you could do will just help prove my results, the more testing the more accurate. FPS has a big bearing on the fragmentation even the type of mesh size of contact and mass the variables are endless.

I will just test the same as I have done with all the BBs I can get to get a comparison on a level playing field.

 
it might be interesting to have the shatter testing done as an impact test, if you have something with adjustable fps dial it in to the common limits (say 1j, 1.5j, 2j 2.5j or whatever) and record the shattering, it might give a better view in terms of what bb's are acceptable for a given site limits and it a bit more easily translated into airsoft parlance even if it is a little less scientific.

i'd be interested to see what laser dot's are like, it's what the local shop sells here and i've had some good results from them, only ever seen shattering when in my testing tube at point blank ranges.

 
Likewise got some more obscure ones here that would be good to test.

Here is my latest update of BBs Tested.

The laser dot 0.3 BBs looked darker than the 0.20s and shattered much easier.

interesting, so they're not that bad with the exception of the shattering.

i did notice shattering with the .3's but only at closer ranges, we're limited to 1j here anyway so it's more the size consistency i was worried about.

 
a weight against a hard metal surface is how he's testing them apparently.

i can confirm they'll shatter at very close range against a hard target.

although going by his scoring system they seem to be equivalent to blasters in terms of shattering.

can't say i pay all that much attention apart from using .2's in the mg42 :D

that said, i didn't pay that much attention anyway until i came on here and had my illusions of .3's lack of range shattered. guess i wasn't taking into account how well the magnus effect lasts.

Interesting topic, the geek in me approves  :)

Would be interesting to see what your test makes of 0.25 Guarder bbs. (from Taiwangun). I may have some left in a bag if you need some to test?

send them to me don't forget weight and date of purchase and exact manufacturer description.

 
Loving this, I've passed it onto a BB brand who might be interested in passing some your way. For science of course :D  

 
I will be posting a further update on my BB testing shortly but I found this which I found interesting it is mainly of BIO BB tests.



 
Glad I found this, was running low and now definitely gonna get some PSBP's!

 
@gasman Hygroscopic BBs (specifically from BB King and derivatives like Nuprol) were a huge problem back in 2015 and 16, but I believe the issues have been rectified. Lots of jammed barrels as the heavier weights used a lot more of this polymer that was swelling significantly after the bag of BBs was open for just a few days. The big giveaway was that they were having to use foil, vacuum-sealed bags and some even came with silica packs.

Whilst you should probably do some hygroscopy tests on the ones you have now, I dare say the results will be far more muted as this manufacturer did fix the problem after a couple of batches.

yeah....reckon he swapped them for crunchy M&Ms  :lol:

wonder how long it will be though until we are all having to use Bio BBs.....hopefully a while or so as still 12000+ ASGs to get through
