They are designed to be able to load from left or right side of the receiver. You can also load one in from right and one from the left side and they couple together magnetically, so when one is empty you just slide it to the full one and carry on shooting. As for knotchy feeling, I have never noticed that feeling.
When I say notchy it's more tight than notchy when putting pellet into barrel
