WWB 9mm 115gr jhp (USA9jhp) velocity

[cookekdjr]

Does anyone have real-world chronograph numbers for Winchester USA (white box) 115gr jhp aka USA9jhp? Winchester lists it at a respectable 1225 fps, but a recent gun mag got only 1075 fps in a G26 (yes, I know its a short barrel but the g26 usually gets about the same velocity as a BHP). I'd thought about getting some of the USA9jhp for when I run out of the high-end stuff I usually carry. I'll consider it if 1225 fps is realistic, but the 1075 number is a little too much like 380 for my tastes.
Thanks,

David

I got around 1180 fps when I chronoed it about three years ago.

Thanks

Forgot to add, that was a Kel-Tec P11 I used. Short barrel, traditional rifling.

Do you have a preference for the 115gr 9mm loads? If not, you might want to consider the 147gr WWB hollowpoints. They run about $14/50, and perform pretty well in expansion/penetration tests. It's become my carry load.

 

[cookekdjr]

Yeah, just about every 147gr performs well. I just seem to shoot the lighter loads better. Don't know why. I guess I did ok w/147gr Hyrdashocks. Maybe the 147gr wwb is the way to go.

Cookekdjr: 1075 fps does sound about right for a G26. I have never seen a report that shows a G26 duplicating the ballistics of a BHP. Perhaps you have a link of know of a source of this claim?

As far as a Kel-tec P11 getting 1180 ft/sec (355 ft-lbs) out of a 3.1" barrel (with a very leaky chamber) - I highly doubt it. Naked Prophet - you need to double-check the distance from the barrel to the chronograh. If you are too close, you can get erroneous results, especially from P11's, since they have a lot of muzzle blast. Tests done on the Rohrbaugh have had this problem. The most energy I have seen delivered from a P11 is 321 ft-lbs (I believe it was a Combat Handguns article), and that was with Cor-Bon 115gr JHP rated at 420-470 ft-lbs from a 4.4" barrel.

Fifteen feet. Three shots, all within 10 fps.

In the second link, please see Mr. Camp's reason number "6" for selecting the G26 as his choice in polymer pistols, which states:

The Glock 26 does not give up much with most ammunition despite its 3.46" barrel. This was a pleasant surprise. Elsewhere on this site, you will find "Glock 26" velocities listed if interested. It should be noted that a couple of favorite standard pressure loads do not quite "satisfy" when used in the Glock 26. Federal 115-gr. JHP and the now discontinued 124-gr. Nyclad simply don't work as well in the short barrels as in those 4 or 5" long. Triton, Corbon, Winchester, and other newer +P loads give virtually the same velocities from the Glock 26 as did my Hi Powers, albeit usually to the low side. However, differences were not great, velocities remain well in the ballistic envelope at which the bullets are designed to expand, and on the receiving end, there's probably no practical difference.

I have noticed from reading a few reviews at other gunmags that the g26 typically gave velocities more typical of longer barrels. Can't remember where, but I remember they confirmed Mr. Camp's observations.

Ya didn't say it was +P+.

I am still surprised that one tester got 1225 ft/sec with the G26. I am wondering if the chronograph was too close to the gun. I tend to believe 1075 figure more.

Sometimes a worn-out barrel, such as in an old BHP can do a lot to reduce the velocity. Over many styles of ammo, a good-condition BHP barrel should outperform a 3.46" barrel significantly. I'd have to see more types of ammo tested between the two guns. And this testing should be done on the same day with the same chronograph to get more consistent results.

 

[ABBOBERG]

I finally got to test the Winchester 115 JHP (USA9JHP) in the G26 and the Pf9.
I got 1014 ft/sec average from the G26 and 1008 ft/sec from the Pf9.

I don't know where anybody can buy this ammo in +P+. I didn't see anything of that nature printed on the ammo box that I have. I am assuming by the velocities I got that this stuff is not +P+ ammo.

After running 44 styles of ammunition through my G26 I have learned that there is nothing ballistically "magic" about this gun. I actually like shooting it, but a gun that I set up with the same length barrel but with non-polygonal rifling had almost identical ballistics with all these styles of ammo. I am assuming that people compare the G26 to the BHP because the BHP might be on the low end ballistically of the big guns (?). A better comparison would be the G26 versus the G17. Now you are comparing apples to apples.

Based on experience with 44 styles of ammunition, the G26 will lose about 55 foot-pounds of energy relative to a full-sized gun. With the Winchester USA9JHP it loses 52 ft-lbs of energy versus a full-sized weapon, such as a G17.

I went back and looked at my records, and the rounds I tested were the 115gr FMJ winchesters. Don't know why the FMJ would be hotter.

 

[ABBOBERG]

I have chronoed my G26 extensively now, and the overall average for WWB FMJ is 1131 ft/sec. Not bad for a 3.5" bbl. My Kel-Tec PF9 averaged 1087 ft/second with the same ammo.

I've chronoed it out of a G17 and G26. Was fairly new vintage (05 or 06).

Altitude is 5200, temp was 40F
