They do not make 30 gram BB's. Although, the do make .3 gram BB's which is what I think you meant. Almost every online airsoft store sells them. I love Airsoft GI (Link below) because they have amazing customer service and quick order processing. I highly reccommend you buy from them.
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.
6mm bb is the size, and the .20 means the weight. They are usually measured in grams rather than ounces. You can get a variety of weights, but generally they are all the same size - 6mm. The weights are .12 gram, .20 gram, .25, .28, .30 grams are the most used. .12 grams are the lightest and usually come with cheap guns. Use .20 grams and buy a decent quality, rather than from a big box store. Go to a reputable airsoft store for your bbs. Cheap bbs will cause gun breakages.
yes, you can. the .20 and .12 mean .20 and .12 grams it doesnt really matter but the .20`s usually go straighter whereas the .12`s being lighter curve up. if your gun says .12 bb`s its usually because its weaker. .20 bb`s wont wreck it but wont go as far in a .12 gun
I believe this comes with a high cap magazine. there should be a trap door right next to where the bbs would feed through. You would open trap door, fill mag will bbs and there should be a wind on the bottom of the magazine. spin that about 20 - 30 times and you should see the bbs loading up.
If you are talking about airsoft bb's, then yes. Most bb's fall between .12 grams and .30 grams, and a 20 gram airsoft bb wouldn't work well.

No airsoft gun under $100 is going to last for more than a few games, so none are truly "good"
There are 6 teaspoons in 30 gm.
