Federal 38spl + P HST Micro
Well I had a chance to chronograph this ammo. At about a buck a round, I only shot five through each of three guns. Not truly scientific with such a small sample, but it appears to be right on for factory claims regarding consistency of velocity, but in my 2" & 3" guns the velocity is well below the factory published number of 890 fps. I do not see on Federals website what barrel length or type they are using for their numbers. 2" S&W M337: High 800 fps Low 799 fps Yes, a total for five shots of 1 fps variance. 3" Custom Colt Agent: High 859 fps Low 855 fps Extreme spread of 4 fps. 4" S&W M67: High 889 fps Low 885 fps Extreme spread of 4 fps. Just for a control group, I then fired five Federal 148gr HBWC Gold Metal Match through the M67 for an average velocity of 753 fps and an extreme spread of 26 fps and a standard deviation of 10 fps. This M67 will shoot into 3.5" at 50 yards with the FGMM ammo off of sandbags. Ammo lot # R12P1394144 Federal Premium P38HST1S 130gr HSP JHP 130gr |
