I had a similar problem between using Aguila and Fiocchi ammo. The shape of the bullet of the Aguila ammo is different than that of the Fiocchi and will not function reliably in any of my 22s except my Rough Rider.
Your photo shows one round noticeably longer than the other plus it appears the shape of the bullet is different, it's my opinion that is what's causing the problems and not the mags.
Here's the photo I took of the 2 rounds:
The difference is very slight, but enough to cause a rash of problems. I'm staying away from Aguila ammo, there's plenty out there that works in my guns, maybe I just got a bad batch.
