Aging is tough and I can't remember how to load the original mag, I also have CARM mags that are simpler to use but want to use the RAW mag too. Many thanks
Turn the top clear plate in the direction the arrow is pointing (right) until it stops and the first loading hole is lined up still holding the top plate that is under spring tension, then drop the first pellet in then you can let go of the top plate and the first pellet catches then turn the top plate to each subsequent loading hole. Mine are RIGHT loading magazines. Left loading magazines may load the opposite way
but still in the direction the arrow is pointing.
