"The new 357 Magnum LEVERevolution® ammunition features a 140 grain FTX (Flex Tip®
eXpanding) bullet at 1440 fps from a 7.5" revolver and 1850 fps when fired from an 18" carbine.
44 Magnum performance is equally impressive with its 225 gr FTX bullet leaving the muzzle of
a 7.5" revolver at 1410 fps and reaches 1870 fps when fired from a 18" carbine."
How do this compare ballasticly to premium ammo already out?
