Tuning .22 Beeman R9 Goldfinger Repower Project

Recently, I was able to purchase on E-Bay an absolutely like new, older Beeman R9 in .22. Upon inspection, I don't believe it had ever been shot, and if it had, hardly at all.

Upon receipt and after inspection, I cleaned the barrel and mounted a Helix Element 6-24x50 FFP scope on top of Sports Match vertically adjustable dovetail mounts.

It shot really well upon receipt with solid and tight 10 shot groups, especially with the Predator GTO Lead Free pellets. It did have considerable spring buzz evident and the trigger needed some work to suit me.

I proceeded to disassembled the rifle completely, and removed all of the original lubricant. Next, I removed the piston sleeve and the old style cocking shoe. Then I installed a new Vortek PG4 Steel HO kit, As I have installed several of these kits lately, I did remove one coil from the spring (net = 30 coils) to be certain it wasn't overpowered and would lock-up easily, and my goal is always 14.50 to 16 ft lb of energy as I find the accuracy of the Weihrauch series rifles to be pretty solid in this energy range. I installed a new style cocking shoe.

While reassembling, I tuned and re-lubricated the Rekord trigger to break clean with no travel coming off of the first stage. I remounted the scope, and the results can be seen below.

As a side note, in .22, more of my spring rifles than not, show strong preferences for the Predator GTO pellets. If you haven't tried them, though more expensive than conventional lead pellets, you may want to experiment with the GTOs. My Air Arms TX200s and ProSport rifles really like them.

As you will see below, I got lucky and hit the desired FPE range almost dead on with the lead pellets, and because of the higher velocity, received even more energy with the GTO pellets, while still being the most accurate.
