This was my first trip to range with my new 15-22. I had the same issue today with FTF and the firing pin hitting the side of the round. I done a lot of research on this gun before I bought it and already knew to make sure to stager each round. I started with CCI mini-mag and had 2 FTF within the first 100 rounds. Switched to Federal champion 525 bulk pack and ran perfect, shot around 100 rds. Went back to CCI and had 3 more FTF shooting a total of 175 round of CCI with 5 FTF. Continued with Federal and only issue I had was one time bolt did not hold open on last round. I shot around 400 rounds of the Federal. Now I only have 1 magazine so its not that. I do remember during my research that the round needs to be angled up for better feeding so I was looking for that as well. Let me know what you find out.
