Anyone chronographed Winchester 38 Spl +P 158 gr LHP?
I'm considering buying some but before I do does anyone have chronograph data for this load to share in 2, 4 or 6 inch barrels?
I hear that it chronographed less than Remington's version (R38S12) but don't have any data.
Thank you

Here you go:
2" (M60) 805
3" (M337) 824
4" (M19) 876
5" (M27) 898
6" (M19) (967) Note; This M19 has a "fast" barrel.
Let's hear what you get.

38 +P
Is this ammo from the older silver/black box ? I say older because I haven`t seen any in a while. Thanks, John

Revolvers are notorious for varying in velocity from revolver to revolver, even in the same model revolver with identical barrel lengths.
Cylinder gap is a big variable along with chamber and throat dimensions, forcing cone dimension and bore dimensions.
If you are shooting the same ammo lots in the same revolver, you can draw some conclusions about relative performance in that revolver, but it won't necessarily be generalizable to other revolvers.
----
There's also the issue of how the data is sampled and whether or not the results are statistically significant. For example, the velocities below may or may not reflect significant differences:
2" (M60) 805
3" (M337) 824
4" (M19) 876
5" (M27) 898
6" (M19) (967) Note; This M19 has a "fast" barrel.
It if the sample size is small (less than 10 at a bare minimum) the differences in the average velocities between most barrel lengths are suspect.
Even if the ammo tested had a fairly average standard deviation in velocity of 25 fps, that SD would mean the differences between the 2" and 3" results and the 4" and 5" results are not significant, even at the fairly low 67% threshold.
-----
The ballistics by the inch data you often see quoted in various threads fails this standard spectacularly, as they use 3 rounds fired over 2 chronographs in tandem to get 6 data points - which is really just 2 sets of measurements for the same three shots now confounded by differences in measurement error. And even 6 shots would not be any where near sufficient.

A few years back I returned 3 boxes of that Winchester (FBI load) because they were mis-marked (+P) standard velocity loads. I Chronographed them and instead of the +P velocities, I got low 730's. Winchester sent me a letter of apology and a refund check.
Even if they were the +P version, they are vastly watered down and out of a 2" M60 don't expect more than high 700's. The Remington FBI load is only marginally better.
My suggestion would be the Buffalo Bore FBI Load which is the same 158 grain LSWCHP but out of a 2" Chiefs Special you WILL GET 1000 - 1025 fps consistently. From a 4" bbl. you will get 1130 fps or so. A 6" barrel yields close to 1200 (more of a Magnum if you will for 158 grain bullets). They also make a non +P version that will give to around 860 fps. from a 2" Chief's. Buffalo Bore's listed velocities are exact and you will actually achieve what they say and sometimes a hair more. I have NEVER seen that from any other ammo manufacturer! Both penetrate and expand well.
Another viable defense load is CCI/SPEER Short Barrel 135 grain +P Gold Dot. It will actually chronograph (around 830 - 840 from a 2" Chief's) a little less than their stated velocity but will still give you adequate velocity and very consistent expansion. Penetration is acceptable as well. One of the best expanding .38 Specials I know of - if not #1.

My friend chronographed five rounds of Rem HTP 38 Spl +P 158 gr LHP loading. Got an average of 908 fps from his S&W Mod 10 HB 4 inch.

Eric,
Posted this before in one of my .38 Spl. threads I know you read because you commented on them.
All 2", Model 12 or Model 10:
Federal 821FPS
Winchester 821 FPS
Remington 811 FPS
All average of 5 round samples.
More recently, all from the same Model 10-4 6", consecutive strings:
Federal 971 FPS
Remington 969 FPS (Old R38S12)
Remington 970 FPS (Current RTP38S12)
Winchester. Don't have any more, but based on prior data expect it to fall right in with Remington & Federal.
All averages of 10 round samples.
All instrumental @ 10 feet, not corrected to muzzle. Add 2 FPS for 2" and 3 FPS for the 6" figures to correct to the muzzle. Variation is small enough to disregard! Calculated from "Load From a Disk".

Thank you Alk8944, looks like we have a good match between Win and Rem loads.

"In it's hottest factory loading, .38 Spl. with the 158-Gr. bullet in a 2"
barrel gives around 970 FPS at the muzzle, with energy rating around
400 foot pounds." That is a quote by Skeeter Skelton back in 1970s.
I doubt he didn't know what he was talking about. Have things changed
that much? I asked this question on another thread but no answers.

That was probably 38/44 High Speed loads that would do 1100fps + from a 5". Just my SWAG...........

If the local range wasn't closed for upgrades I would chrono Rem, Win and Fed FBI loads from 2" and 4" revolvers and see what I get. I will try to do this as soon as the range reopens.
I also have several older boxes of .357 Magnum ammo I want to check on.

Thank you ArchAngelCD, looking forward to your results.
I would chrono some of mine but my second hand chrono is down, probably for good.
