I purchased my SU-22 three weeks ago. Since then I have ran about 400 rounds through it. I like the gun, but have had some feeding problems. A lot of times the first round will not fully chamber, and I have to force the bolt forward. Other times it will chamber a round, but when I pull the trigger no bang. I have also noticed the magazine fits very tightly. The first 380 rounds where CCI mini-mags. I notcied when trying some federal bulk hollow points it functioned much better. Just curious if anyone else has experienced the same problems. I personaly think it's the shape of the round, that is causing the feed problems from what I can see. Any help would be much appreciated.
