Here Goes;

Tested with a virtually unused (maybe 40 shots from new) .177 Tempest useing 7.9 gn accupels, av 10 shots

Tempest av 395 fps = 2.7 ft lbs

Premier "E" av 465 fps = 3.8 ft lbs

BUT premier was accompanied by a lot of smoke and had a 30 fps spread (dieseling?).

Saying that, shooting it with the tempest it really does feel that much more powerfull with regards to cocking and recoil .

Easily my favorite pistol.
