Nice photo of the Privi ammo in the chargers ("strippers").
However, those chargers are loaded wrongly.
There is a very specific way to load the chargers so that the rounds stack correctly into the magazine, and the illustration shows the WRONG way.
_-_-_
This illustrates the proper positioning of the cartridge bases in the the charger. Rounds 1, 3, and 5 have their bases against the bottom of the stripper, while #2 and #4 have their rims resting ON TOP of the rims of numbers 1, 3, and 5.
I know it looks unlikely, but this is the correct way. Note that either end of the charger, when loaded correctly, can be inserted into the rifle's charger guide and feed its rounds properly into the magazine....they are symmetrical when loaded this way.
The rimmed cartridge necessitates great care to ensure that rims do not get behind rims in the magazine, which causes severe "jams". Not a good thing!
