I did have a problem when I first started using BH209 and Winchester primers. I talked to the Bh209 company and they advised using Federal Mag or CCI mag primers. I was using the CCI mags that day. I may take it to the range again and use the Federal mags primers and see if that happens again.
I don't know what to do. I could sell the gun and get another inline. I did set this Knight Vision up for long range shooting and it excells with my setup. I just don't want it to happen at the wrong time.
