Sig 9mm VCrown Test

[Dudedog]

A while back vaalpens in keeping with the PIF spirit sent me some to try. THANKS!
Very nice looking bullets. The bullets seemed to shoot well even though I was shooting poorly that day.
Testing was limited so I did a short work up to the loads I list chrono #s for.
5" Springfield 9mm 1911 OAl 1.08
Mixed range brass, S+B SP

5"9mm 1911 SIG Vcrown 124 gr 4.9gr W572 (4.9 is the MAX listed charge of 572 but my numbers were slow compared to Hodgdon/Win data)

Just started with the Win 572 (powder picture showing a sample) To me it seems a bit slower than CFE-P . W572 looks a lot like WSF but maybe just a bit larger flattened balls.
Somehow I misplaced the WSF target and as I recall it was the best of the 3.



PS: They cut nice clean holes for HPs

Nice write-up, Dudedog.
From my testing with the V-Crowns, I've found them to be one of the best - performing JHP's out there.
That 5.0gr CFE load looks like a winner!

 

[JimKirk]

I picked up several boxes of the SIG .380 V-Crown ammo.
Haven't had time to test them yet.
But they are good looking bullets.

Nice testing and write up!!!

 

[DeadEye9]

The factory load of these do well also, I've run the 124 and 147 V crowns through a few of my 9mm with similar results. Haven't loaded any as components yet, as I haven't seen them for sale locally. How do these compare to Hornadys XTP bullet for accuracy? I typically use the 124 XTP bullet to load for my weekly Action Pistol shoots. It has proven extremely accurate around ~1150fps.

I hate to open this can of worms, but I owe it to my thr friends:

I bought several boxes of sig v-crown for my .380.
I like them, accurate and reliable......until I had a squib.

I quit using them for carry and started shooting them at my range, without a single problem.

I'm curious as to why you'd associate the squib being the bullet's cause?? Was the bullet undersized or something that could lead to blow-by??

Dudedog, thanks for the write-up. From a defensive perspective it seems your WSF load is closer to the published SIG ammo velocity. I wonder what the difference is between the 124gr and 125gr bullets. The bullets you are testing are actually the 125gr bullet, and probably need more velocity to expand. Probably more geared towards the 357sig than the 9mm.

This is what the 125gr V-Crown looked like after being shot into water jugs at around 1260fps. Held up very well.

Oh no, nothing wrong with the bullet. In fact, I was impressed with them.
It was a powder charge issue. The bullet cleared the barrel, but failed to cycle the action. Factory new ammo.

I regret posting this on dude dogs thread. Totally off topic.
Sorry dude, my bad.

 

[snuffy]

Dudedog, just a comment that you may already know, W-571 is the same stuff as HS-7. Just in case somebody else reading this wanted to try some but only have it in Hodgdon HS-7 cans. OOPS! Jim Kirk corrected me that I was one number off, it's WW-571 that's the same as HS-7! The above post used to say W-572 was the same. Nuts! Getting old ain't for sissies!


Another thing, reference back to the tests I did in my wax media on the V-crowns;

My expanded bullets start at post #43.

I recently bought some "Special Run" Sierra 90 Gr JHPs from Midway because the price was right. They shoot great, and they look suspiciously like the Sig VCrown. I haven't shot any into water etc.

 

[Wreck-n-Crew]

You know it does look just like a VCrown! The star shape in the middle of the lea, the cts in the leading edge of the copper jacket. all spot on. What are the odds someone else makes he exact same HP?

I've bought batches of pulled rifle bullets and sorted them by weights and type. Most of them are easy to tell who de them by the Polymer tip, color, shape, or cannelure. Weight was the only other variable and the lead SP were a little trickier.

 

[Walkalong]

What are the odds Sierra makes them, and the 90 Grainers were a test run they didn't choose to use in the VCrown lineup?

 

[JimKirk]

I mis read the post the first time ....

Sierra does make a 90 grain in the V-Crown.... #9990 they are pretty little things too...!

 

[JimKirk]

Snuffy .... HS-7 is the same as Winchester W 571 .... I am fairly sure 572 is a different powder ...then I could be wrong ....

 

[Walkalong]

I just searched and yea, in .380. A tad slower than I am running them in 9MM.

You should see a 90 grain in action out of the 357 SIG.... I haven't did so with a V-Crown ...but a 90 g hornady xtp ..... close 1700 fps ... Puff goes a water jug

 

[snuffy]

Jim, you are correct, brain freeze!

572 appears to be replacing the venerable W-571 which has been discontinued. There's been little testing on it yet, might be a good 9mm powder. I edited my above post.

 

[JimKirk]

Snuffy ....there is some good 572 data out there now Hodgdon has a fair amount they put up not too long ago .... Even for the 357 SIG ..... Lots of others too. Supposed to take the place of one of the SR powders they stopped making .... I get those numbers confused , so I won't try to name the one they said.... Hodgdon Put out some work on their latest powder instead of waiting like usual.

 

[Wreck-n-Crew]

Not sure we are on the same page but I guess what I was aiming at was that it was the same bullet. My understanding is that Sig doesn't actually make it's own bullets? Kind of like Underwood and Black hills?

 

[Walkalong]

I would assume you are correct until proven different. That Sierra "Special Run" bullet seems to agree.

 

[JimKirk]

This is a quote from Sierra's web page for the 90 gr V-Crown bullet....

"Sierra Bullets® has partnered with SIG Sauer® to bring you the ultimate defense bullet line delivering optimal weight retention and expansion at all effective distances combined with Sierra’s world renowned accuracy. The line features a stacked hollow point bullet design with additional hollow point cavity."

"
9 mm (.355) 125 gr. JHP V-Crown
Sierra Bullets® has partnered with SIG Sauer® to bring you the ultimate defense
bullet line delivering optimal weight retention and expansion at all effective distances combined with Sierra’s world renowned accuracy. The line features a stacked hollow point bullet design with additional hollow point cavity. For the #9924, #9925, #9465 and #9820 a cannelure halfway up the shank locks the jacket to the core ensuring maximum weight retention and terminal expansion.

The #9925 was introduced in November 2015."

I think the odds are pretty good. Here's a pic of both: the special run sold by MidwayUSA awhile back and a new box of the Sierra V-Crowns. The only difference that I see is that the "Special Run" has an rounded ogive where the V-Crowns are a truncated cone. Both are excellent, especially for Walkalong's "Little Lasers"

[JimKirk]

Those special runs look a lot more like the Sierra #8100 profile than they do the V-Crown style ... I don't have any on hand one to look at the center punch compared to the other ....

But my .380 ammo made by SIG has a more rounded profile compared to the other V-Crown .... Look in the photo posted above of the box and a bullet SIG ammo....

I am wondering if they make a different bullet just for SIG.....

 

[vaalpens]

It seems I will now have to buy some quality 90gr JHP's just to try them out in 357sig. Thanks JimKirk!

Hodgdon Data says Winchester 572 will yield 1696 fps with a max load of 10.3 grs ... HS-6 at 10.8 grs. yields 1634 fps ... with a 4" ... my barrel is 1/2" longer .... I get a few fps more than that with the HS-6 ... have not tried the W572 YET .... accuracy is no where near what it is with the 124 gr XTP ....
