I had that issue with my very first magazine. In my case it was on me because I didn’t load the magazine properly. I wasn’t pushing the rounds all the way to the back of the magazine. Mine did exactly what you are showing. Try making sure you push the rounds as far to the rear of the magazine when you load them. I think if you do that it will fix your issue.
Thanks - I will try that. I plan on going to the range tomorrow morning to test SK Rifle, and SK Long Range, against SK + (what I'm using now). I hope it is as simple as that seating in loading the mags. I can be diligent - sometimes.
I shot a match Saturday - 46yards out to 234 yards - and I bet I had at least 4 miss feeds. Costly in time and rounds lost.
