the white box is great stuff, i have never seen a rifle that would not shoot it well and in most cases really well, however, it chronies no where near the 3600fps in my guns one is a 24" tube, I usually get around 3300fps with it. if you run the #'s you should only use it for less than 200yd coyotes and small varmints, If you want some good ammo for everything pick up some black hills reman with a 50grn vmax, it is accurate, quick and most of all only ever so slightly more than white box, but is nice to be able to carry 50 rounds in a little white box in your pocket
