Will see how much it takes to crush them with a vise grip. 
Measure how many turns of the adjustment knob it will take to crush them.

As a engineer major you will need 20+ shots/ BB's of each kind to get a accurate measurement. If you need help with all the math and stuff, I would be glad to help, and/or steal it for a project at school

Also Whats the internals for the PDW so you can have a what the fps should be, then you can see what the differences of the bbs are. Like I said im an engineer major so if you need any help feel free to pm me.
Cant wait to see what the results are.

I have a load of bb's coming from AEX, so I will test those and the many I have here at my house as well.
I am getting a chrony here on Tuesday, as well as getting a digital scale to measure the weights.
I am going to use "x" brand for the base fps of the PWD, and then go from there. I do know that it has a trimmed down 210% spring inside of her. So the fps is going to be up there but nothing to unheard of.
Looking though my ammo I have .20, .23, .25, .27, .28, .30, .36, .38, .40, .43, and .46. I think those are all the correct weights for them all. But like I said, I will be weighing them all as well.

I have a question for all you experts. What is the best quality .3's out there to use in a high quality gun . Every brand says the same thing," The best bb's out on the market!!" and I really don't want to put a crappy BB into my new gun

My wife is compiling all of the numbers right now....

And instead of pulling out my PWD, I used my shotty....... and dang that thing is really consistent.
Averages...... 10 shots were put across the pro chrony.
P-Force .20g's - 372.67 fps
Airsoft Elite .20g's - 371.4 fps
GoldenBall .23g's - 355.7 fps
Green .25g's - 346.03 fps (unknown brand, have had for a while now)
Bioval .27g's - ????? Chrono wasn't able to see them
Javelin .28 g's - 324.779 fps
javelin .30 g's - 317.83 fps
Bioval .40 g's - 275.35 fps
Madbull .40 g's - 272.23 fps
Javelin .43 g's - 270.06 fps

Will get the scale here in a day or two, and will pull some weights out of the lot of ammo.
The reason why some of the same weight ammo is the same color, is due to the materials that are used to make the bbs that density. And due to the minimal amount of materials that are currently used, they are the same color. But I have read reports that say they are in fact different ammo.

I have not been following this thread much, but am very interested in these results. Will you be doing more tests with the same weight bb, but a different brand to show the differences in the fps outputs? That is, will you have a list with say around 4-5 brands of .2g bbs, so we can see how all the different brands compare? I saw you had a couple per weight bb, but if possible, would like to see some more comparisons for each "weight class".
Nice work so far, very interesting stuff.
