Winchester WWB115 JHP, WWB 147 JHP, Silvertip 115 JHP,
Ranger 147 JHP, and WWB 115 FMJ

So - two weights of White Box JHP defence ammo, Win Rangers, the Win Silvertips, and finally a re-run on White Box std FMJ. Having done ten shot strings and wanting to keep same format as previous, I will''double up'' with the entries in tables below in the row showing String Velocities - also rounding up or down with decimal components of chrono readout.

As before, the figure for muzzle energy is formulated by using the average velocity from chrono readings.

First - the WWB 115 JHP .....

Winchester White Box 115 grain JHP
String Velocities -	995 fps 977 fps	1009 fps 991 fps	982 fps 966 fps	990 fps 1014 fps	984 fps 960 fps

Low Vel	Hi Vel	Av Vel	Spread	Std Dev'n	ME
960 fps	1014 fps	989 fps	54 fps	16.79	250 ft lbs

Quite a large spread ..... and not an over impressive energy figure. The last shot of the string was a partial FTE .. in as much as, the case was just held in the ejection port thus halting slide closure.. Clearance was very quick and simple. Expansion Test .

Next is the WWB 147 JHP .....

Winchester White Box 147 grain JHP
String Velocities -	973 fps 971 fps	982 fps 1007 fps	1004 fps 971 fps	957 fps 967 fps	972 fps 955 fps

Low Vel	Hi Vel	Av Vel	Spread	Std Dev'n	ME
955 fps	1007 fps	976 fps	52 fps	17.40	311 ft lbs

Surprising here how close the velocities are to the 115 grain version . and yet we have a significantly heavier bullet. As a result, the energy figure goes up nicely. Having said that - it will be noticed that the wetpack tests show little obvious difference between the two weights, which is a little surprising. Expansion Test.

Shots #2 and #4 were FTF's .... the rounds did not lift enough it seemed to get onto feed ramp at suitable angle and so jammed. It is interesting to note that the WWB JHP rounds have quite short OAL's .. around 1.09", as compared with 1.125" for Gold Dots and Blazers. Maybe the slightly shorter round allows for slide forward travel to be too far advanced, before round ready to strip off mag' and so cannot ''climb'' the ramp. Not sure as yet.

Now we move on to new ground for me ...... the Silvertips ........

Winchester Silvertip 115 grain JHP
String Velocities -	1039 fps 1035 fps	1040 fps 1039 fps	1046 fps 1039 fps	1044 fps 1036 fps	1023 fps 1026 fps

Low Vel	Hi Vel	Av Vel	Spread	Std Dev'n	ME
1023 fps	1046 fps	1037 fps	23 fps	7.28	275 ft lbs

Apparent useful velocity figures, and a very impressively low spread figure along with good SD. This brings ME figure up to an acceptable level. This however needs to be seen against bullet performance which can be seen in the section on expansion tests.

More new ground ...... the Rangers ........

Winchester Ranger 147 grain JHP
String Velocities -	868 fps 856 fps	853 fps 811 fps	856 fps 849 fps	852 fps 844 fps	862 fps 851 fps

Low Vel	Hi Vel	Av Vel	Spread	Std Dev'n	ME
811 fps	868 fps	850 fps	57 fps	15.09	236 ft lbs

Not over impressive velocity figures and so also not in my view a very useful energy figure. This was another example where expansion tests showed some strange results.

Finally on this Winchester page ........ WWB 115 FMJ's ......

Winchester White Box 115 grain FMJ
String Velocities -	1004 fps 1017 fps	1013 fps 991 fps	985 fps 1004 fps	1033 fps 998 fps	1016 fps 1019 fps

Low Vel	Hi Vel	Av Vel	Spread	Std Dev'n	ME
985 fps	1033 fps	1008 fps	48 fps	14.35	259 ft lbs

For a lower priced ammo this is quite acceptable. The first test I did on these originally however had the chrono somewhat closer to the gun - thus higher figures in that case. I have since tried to maintain a distance of about 6 feet.

None of this defensive ammo from Winchester made me want to rush out and buy more! It was either slightly unreliable regarding function in the gun or, bullet expansion characteristics seemed far from ideal - from this gun.

Having said that, the WWB FMJ is adequate as a practice round even if as some people find, there are occasional malfunctions - not something that has given me any trouble in my gun however.
