I've got probably 5-600 pellets through the rifle since changing the springs so I thought I'd chrono it again to see how compared to before. The rifle had two RH twist springs in it, I replaced them with a RH and LH twist spring. It seems the 7.33's don't like the speed and the 7.87's do, can't really see any difference in the 8.4's.
I have a new Maccari spring to install, after I try it I may install one of the old RH springs just to see how it shoots.
