Yes, muwahahahaha and tooth testing, who volunteers??? someone with good dental insurance, come on, do it for science. You will be internets famous.

The thing is, until everyone agrees that they are safe to use, you risk looking like you don't care about other players' safety and that you are only concerned with gaining an advantage.

I've used these things myself, and I know they are safe, but others have not and may take a little more convincing.

The lense thing is true, ANY bb; whether it be Styrene, BIO, Graphite Coated, Silica or Aluminium will scuff or otherwise make a mark on a goggle at 400fps up close, so it's a moot point. We know the rated goggles can take it, it's a good piece of information to have "just in case" someone gets shot from within obvious mercy range.

Like I said before, everyone needs to understand the results and draw their own conclusions, not go on paranoia. Even if you still don't feel comfortable with their use, at least you made an informed decision and not one based on hearsay and conjecture.

All BBs are harder than skin..

All bbs will break teeth

The energy carried by the projectile is constant over Mass x Velocity regardless of the material. Particularly considering dimensions are also constant.

Getting shot with a glass BB is no different than getting shot with a plastic one of the same size and weight shot at the same speed.

From a physics standpoint all the "issues" with these bbs are unfounded.

my only issue with them are they are a bitch to clean up

upside is for a home plinker shooting into a proper trap.. they are very likely re-usable

While 'force' from a pure physics perspective may be equal -- the test/pictures posted would seem to indicate the clear rounds act like "FMJ penetrators" , compared to the std rounds which spread the force on impact across a wider area?

If all things were truly equal - the impact pictures & wounds would tell an identical story no?

As stated, we need a much bigger sample space.

no I don't think so ... 2 different forearms .. and no certainty if the angle of incidence of the shot was the same .. this was at best an informal test with anecdotal results.

these are facts.

the size of the projectile is the same
the mass of the projectile is the same
the velocity of the projectile is the same

therefore the kinetic energy of the object in motion would be identical.

the question is .. what is the energy transfered to the target upon impact?

I'll concede that plastic to hard surface some energy is dissipated to the deformation of the plastic bb that would not be dissipated in the silica bb

but on a plastic or glass to soft surface ( such as skin ) the fact that the material is harder than the impact surface indicates that no energy would be dissipated to the deforming of the BB .. because it does not deform.

Deceleration and energy transference to the soft surface would be the same for either projectile.

Therefore these bbs are no more or less safe than their plastic counterpart.

Except in the impact to teeth.. where I expect they will shoot out more teeth than plastic bbs


Ballistic Jelly would be a good way to illustrate this

EDIT: Response got addressed.. whoopsies

Agreed. A tree branch snapping back and hitting you carries and transfers more energy than either type of bb... People wanna play war but don't wanna get a boo-boo? Head back to the Xbox.

On the other hand, stepping on them could possibly be even more unpleasant than with a white BB because you're not expecting it.

NURF guns may fill the niche that some are looking for.

For me, as a result, far less damage done to the coke can compare to normal bbs...

I copied this from the other thread, I thought it would interest those here.

Jeez...never seen anything so controversial...can't we just....

...shoot someone with them at a game
...film the survivor
...have someone intelligent write it up and post it to ASC
...let some younger guy post it to youtube
...let some kid facebook it
...let some even younger kid twitter it
...and get on with things?

And they come in ultra-cool colours like "Lego Brick Orange - LBO", and "Toy Box Blue - TBB". Look for them in your April Magpul catalogue.

All I can really say is cover one can cover their mouth or wear a mouth guard if they want. I personally wouldn't enjoy losing a tooth either, but just taking a bit of extra care to keep your face out of the line of fire when speaking, keeping your mouth shut when it is, or covering it with your hand if you're really worried would probably help a fair bit.

My name is MADDOG, I am a clear silica bastaholic. It has been 3 days since my last silica usage. Its a struggle, not to use, everyday.

You are correct bro. I have seen him use them on at least two of the three occasions, and not a peep from his any of his victims....and yes, there is a lot of them. LOL

In terms of the ballistics, they are clear, and so you can see that there are no air pockets within them....they fly true and consistent from shot to shot every time.

perhaps you should volunteer at FR this Sunday maybe? 130 players is a good audience.

Lanny can bring his camera
