Federal - Hi-Shock 115 grn and Hydra-Shok 135 & 147 grn

The Hi-Shock (C9BP) was the supplied ammo and so tested at all distances. Thus three samples of five.

With limited availabiliy of the Hydra-Shok, I only got one string of five for 135 grain, and two strings of five for 147. I will tho add an extra five string for each from first test data (minus SD result at that time)

String velocities are rounded up or down to get rid of decimal point. Muzzle Energy (ME) is based on the average velocity (Av Vel)

Federal Hi-Shok 115 grain JHP - sample #1
String Velocities -	1030 fps	1007 fps	1034 fps	995 fps	1005 fps

Low Vel	Hi Vel	Av Vel	Spread	Std Dev'n	ME
995 fps	1034 fps	1014 fps	39 fps	16.70	262 ft lbs

Federal Hi-Shok 115 grain JHP - sample #2
String Velocities -	1006 fps	1008 fps	1039 fps	977 fps	988 fps

Low Vel	Hi Vel	Av Vel	Spread	Std Dev'n	ME
977 fps	1039 fps	1003 fps	62 fps	23.60	257 ft lbs

Federal Hi-Shok 115 grain JHP - sample #3
String Velocities -	998 fps	996 fps	986 fps	991 fps	984 fps

Low Vel	Hi Vel	Av Vel	Spread	Std Dev'n	ME
984 fps	998 fps	991 fps	14 fps	6.08	251 ft lbs

Rather a large spread ..... and strange how the third series saw no velocity over 1000 fps! Let's again combine figures to get a feel for the fifteen string.

Low vel overall - 977 fps
Hi vel overall - 1039 fps
Average (of averages) - 1003 fps
Max spread - 62 fps.
Average ME - 257 ft lbs.

Spread is not that good and in particular, the energy figures are not that high.

Next is the 147 Hydra-Shok .. the first two series done fresh, the third set of figures taken from test #1.

Federal Hydra-Shok 147 grain - sample #1
String Velocities -	818 fps	806 fps	831 fps	840 fps	821 fps

Low Vel	Hi Vel	Av Vel	Spread	Std Dev'n	ME
806 fps	840 fps	823.5 fps	34 fps	12.92	221 ft lbs

Federal Hydra-Shok 147 grain - sample #2
String Velocities -	821 fps	816 fps	819 fps	829 fps	855 fps

Low Vel	Hi Vel	Av Vel	Spread	Std Dev'n	ME
816 fps	855 fps	828 fps	39 fps	15.93	224 ft lbs

*Federal Hydra-Shok 147 grain - sample #3 (previous data)*
String Velocities -	799 fps	823 fps	825 fps	824 fps	832 fps

Low Vel	Hi Vel	Av Vel	Spread	Std Dev'n	ME
799 fps	825 fps	821 fps	26 fps	N/A	220 ft lbs

Surprising here how low the power factor has dropped, even when compared with the 115 grain above. Combining figures for the string of fifteen we get ....

Low vel overall - 799 fps
Hi vel overall - 855 fps
Average (of averages) - 824 fps
Max spread - 56 fps.
Average ME - 222 ft lbs.

Does not shout out as a choice!

Finally is the 135 Hydra-Shok .. only one string of five recorded during this last test but will again add a five string data set from the first R9 test day (no SD).

Federal Hydra-Shok 135 grain - sample #1
String Velocities -	912 fps	920 fps	920 fps	910 fps	925 fps

Low Vel	Hi Vel	Av Vel	Spread	Std Dev'n	ME
910 fps	925 fps	917 fps	15 fps	6.24	252 ft lbs

*Federal Hydra-Shok 135 grain - sample #2 (previous data)*
String Velocities -	892 fps	914 fps	916 fps	920 fps	894 fps

Low Vel	Hi Vel	Av Vel	Spread	Std Dev'n	ME
892 fps	920 fps	906 fps	28 fps	N/A	246 ft lbs

Power factor here better than the 147 grain... Combining figures for the string of ten here we get ....

Low vel overall - 892 fps
Hi vel overall - 925 fps
Average (of averages) - 911 fps
Max spread - 33 fps.
Average ME - 249 ft lbs.

Spread also better than the 147 grain.

This ammo does not show up too well overall .... regarding speeds, energy etc. One could regard it perhaps as adequate but not remarkable.

You may next like to look at Chrono Data - Remington .......
