If there is it's not enough to worry about. Crosman handles Copperhead BB's they are .177 caliber and are 5.1 grain. Daisy handles, Daisy BB's, that are .177 and 5.1 grain. The choice is yours.
MarksMan also makes BB's called Laserhawk that are also .177 ( no grain info)
Personally I shoot Gamo BB's ( Called Gamo Round Balls.) they are .177 caliber but 8.2 grain, A little heaver than the other BB's. I use these because they are made out of lead. The lead is soft enough to take advantage of the rifling in the barrel. This makes them spin and fly straighter than regular hard BB'. If your rifle or BB gun is a smooth bore ( Not rifled barrel) then it doesn't matter what you use.
They were made by both Daisy and Crosman. Any BB gun model starting with 799 was a Daisy and any BB gun starting with model number 126 was a Crosman.
Crosman doesn't make the Grizzly, Daisy does. $40
They are both the same size. .177
Any .177 caliber BB is fine. BB's made by Copperhead or Daisy will work with your 760.
Daisy and Crosman made numerous BB and pellet guns for sears over the years. Without more information it is not possible to answer you.

Yes all the K-Marts that I have been in do carry BB guns for sale. Usually Crosman, Gamo, Daisy and Beeman models.
NONE. Daisy never made a model 1600. Crosman made a powermatic model 1600. Is this the pistol you are referring to/
It was made for Western Auto by Crosman between 1966-70
I suggest Crosman Pellgun oil or RWS pellet gun oil.
Check the model number. If it starts with 799. it was made by Daisy. If it starts with 126. it was made by Crosman. If it is a Crosman (126.) model then Crosman offers a locater service (Free) to locate repair shops that repair older Crosman airguns. If it's a Daisy (799) model then I suggest you contact Daisy and ask them.. See the two links below.
Here are a few of the most popular air gun manufactures: Crosman, Daisy, Beeman, Benjamin, Sheridan and Gamo
