There is a small door leading to the hopper on the top of the scope, just fill that up.
Actually, its a gravity fed rifle and it the hopper can hold 500 bbs in the hopper, and it fires around 275 fps.
The R71 holds more rounds and is Semi and full auto and cost less. It's a better bang for your buck.
See the link below for the Crosman 1300. It is similar to the 1322 model.
any its not about the weight but the caliber. all airsoft bbs are the same diameter unless theyre a crappy off brand but a .12 gram will shoot out of a gun just as a .52 gram will. but dont use either one in an r73. idk your fps but .20 gram or .25 is probably the best
