Heavy BB's

In this link there are some 0.36g Aluminum Coated Sniper BB's. I personally would not use them but Im curious if people actually do.

I would assume they are only for target shooting but like I said I was curious if people actually gamed them.

I know the ESS stuff is meant to stop a 12 gauge but Id be a little pissed off if that popped off my goggles :rolleyes:.

Ow

Ya that was my thought. I know it stings enough hitting some one with a .25 MT. I can only imagine those guys. I can see people needing pliers to get them out of the arms.

just because it is alu-coated doesnt mean it stings you more than non-alu-coated 0.36g bb-s. many people use 0.43 madbull bb-s. all you got to know is your MED (min eng dist)

would you want to be hit by option A or option B? both will travel at the same speed for this test.

option A; 2lb feather pillow
option B; 1lb brick

you're suggesting that plastic bb's are marshmallows by comparison. they are not. the C.O.R. is pretty close. a better choice would be
a. getting struck by a rubber mallet
b. getting struck by a rubber mallet painted with aluminum.

both are going to hurt like a bitch but the difference in damage is negligible. it's alu. coated but plastic core. try wrapping tin foil around a tennis ball. it might do a little but not worth mentioning.

no that is not the point, I used extremes yes but the point is it is not just the weight and speed of something that is an issue we also need to consider the density of any projectile. you won't see metal BB's at any airsoft game. aluminum coated or steel or copper or what ever they will not be allowed. were not talking about painted surface colour.

edit* also this may just be a thin aluminum coating but we tested these years ago and they were found to be not safe for field use and banned by the insurance company we had at that time. they cracked jt paintball goggles and broke glass. they simply did not deform like a normal airsoft bb did on impact during the same tests.

Snipers had been using graphite coated 0.36g BBs for years, would you rather get hit by a graphite powder coated BB or an aluminum powder coated BB of the same weight? I highly doubt those are "Aluminum coated", either they are graphite coated and mistaken to be aluminum (some mis-informed would refer to the graphite coated BBs as "metal" coated BBs), or they are solid aluminum (which would be used only for steel silhouette target shooting, not gaming). I used to have some alumium BBs, solid aluminum, they weighted in at 0.29g................. weren't all that great either. I've never heard of anyone using aluminum BBs at games, too hard to find, expensive and not that great quality, but they would likely be forbidden from use if anyone showed up with some.

compressed to the same size and shape... I'd rather the brick.

i think imma wait for the newer depleted uranium bbs.

slightly off topic of aluminum bb's but why is it that a a gun must shoot 350fps for indoor games and usualy 400 for outdoor with .2 what if someone had a gun shooting hotter but compensated with heavier bbs say 420-450 but used .3 instead to lower it the games regulated fps

it is the amount of energy that that matters.

correct. and alu-coated bb's of the same weight and speed carries the same energy. i still wouldn't use coated bb's at a game though, in case the "coating" flecked off and made it into someone's eye.

games are capped at a joule limit, 350fps with .2 is the same joule (around 1.1) as .3 at around 280-290fps ish

The coating won't come off. It might leave a mark in your barrel or on your hard target (little teflon smudge) but nothing much.

Except the real exotic BBs, there is no such thing as metal BBs.

And even if there was, it's the weight that matter, not the material.
A metal BB deformation on impact won't make a difference compared to a plastic BB deformation on impact.
