Paul, thanks for the wonderful work you did on my R7. I doesn't even feel like a spring gun now. I have tried different pellets and they all seem equal in accuracy. I did receive it in time for my birthday on the 4th of July. When I checked the velocity, it was as you said about 620, which will penetrate both sides of a shotgun hull with all types of pellets.
The 500 fps pre tune velocity would only dent one side.
Thanks Again, cstanmiller
