I went and had the girlfriend take me to get a f1 chrony today and tested out my shadow after i had kinda tuned it and put a new spring in.
I have to go home and get the list but the average is about 880's with maybe 10-15fps deviation. This was with shooting crosman pointed (7.9grain) and with jsb's it shot about 860. Ill have a more Comprehensive breakdown tonite.
Dose that seem normal at all? I see some are shooting well into the 900's
-
Seems normal to me. Don't forget that everyone's gun is gonna shoot different pellets at different speeds.
My CDT Tuned Shadow puts the CP's out at 890.

I just recently chrony'd a friends Shadow using his pellet of choice, CPHP 7.9 g , and his rifles FPS average was just around what your is.
I chrony'd one of my shadows using the same pellets and the average FPS was around 930.
Like Mamba said,,, different rifles can shoot at different FPS.

Well at least I know it within a decent range. I was reading a few and some were like around 950+ and kind had me thinking. Makes me feel a little better now :) thanks guys
-
Ditto Jeff, My shadow Sport using Gamo hunter's is in the 930's also. Ed

I have the hunch the velocity deviation is mostly due to the pellets used. The crosman hunting are a little looser fitting than the premiers and the jsb are the tightest in the barrel. These were all that I had at the time to test with. Id like to try something heavyer later on, maybe some jsb heavy's and jsb exacts. Before it proved that the crosman hunting were the most accurate out of the bunch. But with a new spring and the gun shooting normal again it could prove to be different.
Any thoughts?

That is good Jason... I like the small deviation. Now its time to find the right pellet that you new Shadow likes best..:)
