Here is some info from the Chrony. Lube vs Non Lube.
Gamo 440 - CPHP -14fps, Gamo Match WC -43fps Tomahawks -26fps Lube not good for Gamo 440
Crosman Phantom CPHP -5fps didnt have previous results for other pellets. basically no change for Phantom.
Quest 800 - 22, basically no change
Gamo Delta - CPHP -24fps, Gamo Match WC +24fps. Down 24fps with one, up 24fps with the other. Hmmmm.
Cummings B3 - CPHP +78fps (wow!!) GAMO match WC +84fps, (wow again!!)
This is no scientific study as it was 27 degrees here this morning when I did the measuring. It was 55 degrees when I did the first test. The before numbers were from about a month ago, and the rifles have been shot alot during that time.
Great improvement on the B3, the others pretty much stayed the same or went down a bit.
