What makes heavier BBs?

Luckyorwhat · March 17th, 2006, 05:44

Like it says, is it just a different density of plastic?

Ghost Snake · March 17th, 2006, 05:58

Maybe its a different material, maybe its more compressed, I dont know. Does it really matter?

Hades · March 17th, 2006, 06:00

Maybe depleated uranium cores? :shock:

I'm going to go with density of the plastic...I don't think they'll use metal inside...at least I hope not...

CDN_Stalker · March 17th, 2006, 09:49

I think it's a metal powder that is mixed in with the plastic compound, similar to the way the frame for the KSC G19 is made.

Heavy sniper rounds are quite dense. You can work out the specific gravity (density relative to water) at 3.8 of a 6mm 0.43g sniper round. Aluminum has a SG of 2.7 and steel has a SG of 7.8 to put things in perspective.

I note that my 0.43s aren't magnetic so I think steel isn't used as a filler. If you bust one in half, they're white inside so I suspect some oxide filler is used. Alumina for instance is white and has a SG of 3.97. However, it's hard stuff. I would guess it'd be hell on machinery to process alumina (abrasive) so some other oxide is probably used.

Stalkers got it right, only I think its the sniper rounds where you start seeing a metal powder ingredient. I think the .25's are still solid plastic just more plastic product compressed in the mould.

And I don't think all metals are magnetic there MadMax. Also the metal would be a powder mixed in the round. Making a plastic ball around a metal bb would require a new set up on machinery to make instead of just changing the heat/pressure or material in the machine that already makes the current BB's.

Straight 0.43g BBs being white inside? Mine are graphite grey inside. The 0.30g and 0.36g are white compound on the inside, little group of bubbles in the center, and the 0.43g are solid with no bubbles inside.

he was talking about steel. steel is magnetic, genius.

I didn't say that all metals are magnetic. I just ruled out magnetic steels.

ABS has a SG of around 1.1 and is not compressible enough to acheive an SG of 3.8

well, not all steels are magnetic. Some stainless steels are non magnetic. I was just referring to more common steels.

if we had to state the exceptions to everything we ever made a statement about, communication would be a big hassle

Uh oh.

It could be more compressed, or it could just be a slightly different grade of plasic that is more dense. Compressing a solid like plastic is incredibly hard and would take different machinery than normal moulding (not to say it isnt the machinery they are already using and just not using the same functions of the machines with everything they do), there could just be air mixed in with the lighter ones though. There are many different types of PVC for example, seveal thousand different grades if not more, each with slightly different properties (density, elasticity, flexibility, heat resistance, etc.)

Mixing in air can make things strange as it isnt controlable as precisely so some BB's would weigh less or more than others, so chances are its slightly different types of plastic.
