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)

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.

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).

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 .......
