with rimfire cases magazines are ALWAYS a factor--agree with you there...and after reviewing that video with what i know now you are correct that it isnt terribly informative
what i have found works if the rims do not align correctly at the top of the mag; pull back the load assit and flip it upside down and the shells SHOULD line up...least in my case it works
also review the SW online manual from their website...i found the printed instruction a little better personally
Here is all the manual says,
"Orient the magazine as shown (Figs. 13 & 14). Hold the follower down using the loading assist button on each side of the magazine. Hold the follower down only far enough to load one round at a time to maintain cartridge alignment. Feed each round into the magazine until it is held by the magazine lips and is against the rear of the magazine. Place the next round on top of the previous round and repeat
until the desired number is loaded. Do not attempt to load your magazine beyond its capacity."
Let me clarify my post. The 15-22 magazine is a "double stack" magazine (the rounds are alternately staggered). The problem IMHO is NOT the stacking, but rather the orientation of the nose of the round. If the nose is not pointed upward in the proper orientation, the round is likely to misfeed. This is NOT something you can see from the rear of the magazine. You can only see the nose of the last round loaded from the top. Once another round is placed on top, you can no longer see the previous rounds nose orientation. There is no way to tell if previous rounds loaded have shifted nose position downward, from the rear.
I have fired many magazines where it was clear that they were "staggered" incorrectly, and they all loaded and fired just fine, while other magazines that showed proper stacking from the rear, had failures to feed.
I only have 2 other .22lr firearms at the moment. One uses a double stack magazine, and the other uses single stack. Neither has the issues of the 15-22 magazine. As I said in response to another post, I believe the tolerances on the 15-22 magazine make it finicky about different bullet shapes. Those that closely adhere to the tolerances of the 15-22 mag will work just fine IMHO regardless of stacking. But those with rougher or odder bullet shapes and finishes will have feed issues even if stacked properly. In the end, to me at least, it's a matter of bullet nose orientation within the magazine, rather than staggered stacking.
Back in my day ( a loooong time ago) as an Infantryman, we would rap our magazines on our helmets a few times before loading in the rifle, to ensure all rounds were seated against the magazines rear wall. Maybe that's what made me "old and cranky." Too many hits on the head.
