about bad pellets

in two different airguns the same pellet may perform differently, of course. Then again, some pellets vary from batch to batch enough to cause an inconsistency issue when testing. I know this to be true of the .22 Crosman Ultra Magnums (14.3 grain domes). When testing my B50, I recently depleted one tin, and opened another tin from a recent purchase. These Crosman pellets had varying FPS results across my chronograph. I admit I did not expect to see such poor consistency within one tin, but there it was. Maybe good for sinkers? I'd wanted to save a buck or two because I had been testing with Jumbo heavies, but the budget can't take too much of that.
