Consistency issues with the ETEK 3
TOday I noticed a large range over the chrono with my ETEK 3. It started at 268 then after four or five shots ranged from 274 to 312. Has anyone ever seen this? If so what did you do to fix it. The gun is used so I'm sure its broken in. It has an APE OLED board, Zick2 rammer and Hush bolt.
