Plans changed and I didn't make it to the range, but I have some traps at the farm so I tried out both of my new Parkers. Wow. They both functioned like new. I was worried about the single trigger on this GHE since they apparently can be problematic, but it worked perfect. Selector, and ejectors worked as they should and the trigger reset was very nice.
I had a camera set up on my first station. The Champion WheelyBird is running off of a Ryobi 18V tool battery, and it randomly throws following pairs which I see as a feature not a flaw.
Really happy with how the GHE shoots.
