I just received my 22 kit from beretta the other day and went to the range with it. First pull of the trigger. Nothing. Field stripped it put it back together. Then it fired. Phew. I was shooting the federal hp bulk box. 550 count. 36 gr. and I had probably about 4 misfires and 2 FTE. Didn't bother me too much. But just wondering if it was the ammo or the kit. What is some good target 22 ammo to use with these kits. If anyone knows. I shot probably about 400 rounds through it also. It was fun considering I only paid 16 dollars for the box. So glad I bought it.
