What is the difference between 12g and 24 cal airsoft bbs?
You are more than likely getting this off of a batch of ammo
bought at Wal-Mart, but I will answer it for you anyway. Airsoft
BB's come in one size, and one size only, 6mm... no one calls it
.24 cal except for people at walmart trying to pass their ammo off
as higher quality. .24 cal = 6mm The POINT12gram BBs are usually
very very very low quality, but the .25gram bb's are usually high
quality. The 6mm BB's come in varrying weights, the standard for
good guns being .20g. Some people (like me) have guns that shoot
fast enough to allow for a heavier weight like .25 or even .30. The
heavier weight ammo will make your airsoft gun shoot a lot slower,
but the bb's will behave better through a hop up, be less effected
by wind, and are able to cut through brush and grass. To summarize
your answer, the .12g is the wight of the BB where as the .24cal is
the size.
