The Crosman site lists the Bejamin Marauder PCP pistol in .22 as giving 700 FPS.
The Marauder .22 PCP rifles are advertised on some sites as giving up to 1000 FPS. On the Crosman site they list it as giving 900 FPS.
Just youtube .22 marauder and check out the specific chrony testing at pyramyd air - for the marauder .22 cal and .25 cal- they do testing with several pellet brands and weight.
On the .22 cal you can adjust it up 1000 fps levels,...the weigh-off is having less shots per fill.
I've heard there adjustments you can make to get up to 60+ foot pounds with the .25 cal marauder using heavy specialized pellets ( 50 + grains) !....- obviously you'll have less full power shots per fill.
