You need to know which pellet Daystate set their guns up with, 10.5 might be with JSB 8.4 for instance but what is it with Bismags?

People get too hung up on power outputs, 12ftlbs with 8.44 is 802 fps, so your going to have to be at least 780fps to be safely under, 10.5ftlbs is 750fps, so your really quibbling about 30fps.

If you set a rifle at 11.8ftlbs as some suggest your going to be well over if the Police test with Bismags!
