At the last Ft. Ord game it was announced that they wold not allow Bioval BB's to be used over safety issues.

I use them in my M14 and my 226. I know that they are WAY too hard, so I am careful with my shots. They shoot too great to stop using in my opinion.

while i'm right there with you on how great they shoot, I'm err-ing ont he side of safety and encouraging others to do so.

im kinda glad my brother didn't convince me to use the .27s in my m24, cause that might have hurt some people if i did.

good to know, i'll update my thread-head

shot dom 3x in the back of the leg from 15 feet with my p90 at 350 fps with both toytech .25's and then bioval .27's in the other leg from same distance, as well as one shot to the shin with both types of bb. Neither bb did more damage than the other... I think the hardness of the .27's causing class to shatter harder causes a placebo effect of more damage being dealt. If it was on a hard surface such as teeth, then yeah, a .27 would have a higher chance of cracking a tooth, but on skin there's no way it will cause more damage unless you hit a velocity in which the skin would cause a normal bb plastic material to compress some, where the .27 bioval material would not. Until you hit that point, the only extra damage dealt would be from the .02 grams of extra inertia.

This isn't the first time they've been banned from usage. A large Op in Europe banned them after they had gotten the same complaints when BBs were hitting cars, chipping the paint and breaking the glass. The white Biovals are a no issue, as they break on contact like any other round.

I was cranky that day, I donno why :(

[quote="TheJas"]Thanks for the heads up though. I don't want to hurt someone and definitely don't want to see if they go through facemasks...[/quote]

I heard from someone that bio bbs have a tensey to break sometimes on impact, is this true?

So it seems like the white .25s are OK?

something i don't think you gentleman are taking into consideration is polymer density and the way the bb's are formed. I;'ve hit windows and walls with .20 and .25's and could see where they were molded by the break lines.

I've been following this argument on Arnies as well as here. The main things that people are worried about are:

Erik i see what you're trying to argue with the density but the relatively uniform size and weight of a bb throws out that argument. Two things of the same size/shape and weight like two .25g bb's will have the same density. If one were more dense then it would weigh more because there is more material in the same amount of space.

grab a .27 bioval, a vice, and a really small drill bit...

Wrath makes some good points as does Rcas, some simple tests could be done to prove/disprove safety concerns, like shoot some sample BB's at a particular material you know the properties of for example a thin piece of sheet metal(maybe 24gauge), and measure the impact crater, then maybe do the same test using a brick as the impact target to see if the BB breaks or not.

[quote="spot"]But if I have a car and hear enough reports of the same model blowing up when hit from behind I'm probably not going to keep driving the car.[/quote]

[quote]It depends on the size of the point of the instrument doing the puncturing (i.e. a needle takes only a little force, but a bullet takes quite a bit). What you really need is how much pressure does it take to puncture skin.

Even better :)
