I think you mean grams. They come generally in .12 gram, .20 gram, .25 gram .28 gram and .30 gram and a few higher grams than that. Grams are a weight measurement so that should answer your question. Most people use .20 grams in an AEG and .28 or .30 for sniper rifles. 24 caliber I believe means 6mm bbs which is the standard size bb for airsoft.
Airsoft bbs are made up of plastic and are 6mm in diameter and are .24 cal, BBs however are metal and are .177 cal (4.5mm)
The .24 is not the caliber all airsoft bb's calibers are 6mm the .24 is the grams which is how much it weighs.
No, it is a spring gun.
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.
Nope. Plastic BBs are 6mm- about ,24 inches. Metal BBs are smaller- about .177 inches.
