The 7,5joule spring measures 2,9mm wire, 14,6mm coil ID, 33coils counting the ground endcoils.

Made a brass TP sleeve, to 3mm. Less slammy, but the velocity is the same with the 7grs Geco.

Tested 7.33grs JSB, and the consistency is amazing; extreme spread of 6fps, 674-680fps.

Perhaps the spring is the limiting factor now?
Interesting; so if the export spring sold by Sportwaffen Schneider is genuine anschutz and so is the one you have removed the main difference appears to be 0.5mm on the spring wire.
