This rifle was made for sears by Crosman. It really is a Crosman model 400. Crosman has most all their Owner and Parts manuals online. See the link below.
If you are talking about a PCP (PreCharged Pneumatic) rifle. With a .45 caliber pellet, then "Yes" It can. I don't believe there is a 40 Caliber pellet gun.
You can find it on the Crosman web page. The JC Higgins model 180 was made by Crosman Air guns. See the link below
The 620 is a 4.5mm or .177 caliber pellet rifle and is rated around 450 FPS.
It depends on the model and the caliber of the Pellet gun.
A BB pellet is only a couple millimeters thick. The pellets are very small. BB's are usually .175 Caliber a regular Air pellet is .177 Caliber
Pellet guns tend to come in two standard caliber sizes. The first smaller caliber is the most common for pellets guns and is .177 caliber. The second is .22 caliber that can be found on some higher powered pellet gun models.
Depending on caliber, they can ragne from 4-28 grains.
I believe this is a Crosman model 180 made for Sears under the JG Higgins brand name. See the Link #1 below for the owners manual. If this is your rifle then I suggest the following. Crosman offers a service to locate repair shops that restore older Crosman air guns.. See the Link #2 below for more information.

If you are talking about a .177 caliber pellet. Most likely the answer is NO. But if you are talking about a 45 caliber or 50 caliber pellet then the answer is Yes. Pellet guns come in .177, .20, .22, .25, 9MM, 45 cal and 50 Caliber. The last 3 sizes are fired by PCP air rifles (Recharged pneumatic ) that require a scuba tank to charge them to 3000 PSI. They are still pellet rifles just the BIG BOY of pellet rifles.
Usually not. A BB is .17 caliber and a 6mm pellet would be .236 caliber. That means that a 6mm BB gun would be imaginary. There are .17 cal. pellet guns and there are .22 cal. pellet guns. You could drop a BB into a .22 cal. pellet gun and it would probably be ejected if it didn't roll out the barrel first. Always read your owner's manual and become familiar with the recommended ammunition and operating instructions.
