BB's are usually made of steel, pellets are usually made of lead or other soft materials. BB's are not as accurate as pellets. BB's are fired for a smooth bore barrel ( like a straw) and they tumble as they fly. They do not spin, therefore they drift off target easily.
Pellets are usually fired from a rifles barrel. The skirt on the pellet flairs when fired by the compressed air in the rifle. The skirt catches the groves in the barrel and this makes them spin as they leave the barrel. The spinning makes the pellet fly straighter.
BB's only come in one weight (5.1 grains), Pellets come in several different weights. Lighter pellets fly faster but are affected by crosswind. Heaver pellets fly slower but fly straighter and have more knock down power.
yes if it fits but metal bbs cans destroy the rifle
No recommended, Not designed for plastic BB's.
It's designed as a pellet rifle. Forcing it to fire BBs will ruin the rifling in the barrel. Rendering it much less accurate, It's a good way to ruin a pellet rifle.
pellet=no bb's= 6mm plastic not copper.
Not recommended unless the owner's manual says so.
Light .18 gram bbs.
.20 grams
First, check to see that you have a BB gun, and not a pellet gun. Both pellets and BBs are made in .177 cal. A pellet gun will not shoot BBs (in most cases) If your gun IS a BB gun, you will need a gunsmith to check it for damage, stuck items in the barrel, etc.
I would personally buy .25 gram high impact bbs for good precision
Yes, a magnet can pick up steel BBs because steel contains iron, which is a magnetic material. The magnet will attract the steel BBs due to their magnetic properties.
airsoft uses 6mm bbs. Perhaps you are talking about weight? .20 gram is good.
In general, BB guns are smoothbore, and the barrel is larger than the steel BB. Pellets guns are rifled, and fire a lead pellet that is a squeeze fit to the bore. This is MUCH more accurate than a BB. GOOD pellet guns are more accurate than firearms, within their usable range. I have one pellet rifle that will put pellet after pellet into the same hole in the target at 10 meters.
