Yesterday, I was working with my AA TX200 MKIII, a rifle I invested much time and care in tuning and developing, shooting my RX targets, attempting to put a 5.52 mm Predator GTO lead free 11.75 gr pellet through the only 10MM holes in the steel face plates to knock down the 1/4" steel plates.
I was experiencing a lot of fringe hits. I knew that this rifle was something special but I got frustrated and thought it is time to move on to another project. So I listed it on AGN. Fortunately, no one moved to buy it or it would have been gone. It has since been removed and I have no intention of selling it.
After a good night's sleep, I decided to get it back out this morning, and work it through the paces, shooting two ten shot groups with each of 7 different .22 pellets. My memory indicated that when I did this as part of the original tuning project, the Predator GTO was one of the best performers. It certainly wasn't this time.
Below you can see the test results, with the JSB Hades clearly the winner, and shrinking the groups by half from what I was experiencing. For anyone that finds it to be of interest, after completing the 2 shot group tests, I re-zeroed the rifle, shooting three 10 shot groups with the Hades, achieving nearly identical group sizes at an average of 656 fps, with an ES of 9 fps, an sd of 2 fps, producing 15.89 FPE.
The pellet test results are as follows:
