Sig V-Crown 124 gr hollow point

I have been looking for a one bullet does it all load with better expansion than the 115 gr Hornady XTP for my compact and regular size 9mm pistols as well as my Uzi and MP5.

The Sig V crown does reasonably well, but it really needs 9mmP+ velocities.

At about 1015 FPS in my 3” Kimber Micro 9 expansion was reliable if not as impressive as in the later pistols tested, and averaged right at the 18” FBI limit, with one at 17” and 1 at 19”.



In my 4” Kimber Pro Carry at about 1100 FPS penetration was the same at about 18” again with one slightly under 18” and 1 sligly under 18”, but expansion was slightly better.



The most interesting result was with my MP5. At a velocity of around 1350 FPS, both penetrated to 15” and expansion was superb.



As can be seen in the image below, the velocity had comparatively little effect on penetration but had a significant impact on total amount of expansion.



It’s impressive that it will expand over a 330 FPS range and keep the penetration within fairly reasonable limits. Not many bullets will do that. In a 9mm +P or +P+ load it should perform well in a variety of barrel lengths.

With a Kahr 3" with a Xtreme 115 and 124 ball fmj and a max load of Unique powder.....

the 115 got 1168 with 1.12" oal
the 124 got 1112 with 1.14" oal.

The Gold Dots at 1.12" usually run a little slower in my weapons than the plated bullets.

The V-Crown is a great bullet, if you can find them.
I havenot.

Good shooting.

the 115 got 1168 with 1.12" ot about $0.30 eashal

Ed: Midway has them both (124 &125gr) at $0.30 each...

Cheers!

P.S. And now they are $0.24 at Cheaper Than Dirt!

I plan on the V Crown as my JHP when reloading. If you look at SIG loaded JHP ammo, their 10mm is a full power load, and their M17 9mm JHP NATO load looks very nice as well.

Does that SIG/Sierra 125 pictured above look like it would work well in a .357 SIC load? I hear they can be picky about profile because of their short bearing surface.

Thanks for doing that testing. I happen to have done a lot of development with that bullet since it was 1) what I could get when shopping some months back, and 2) the most accurate bullet in my first testing, as compared to the Horrnady XTP and a few others. I can say it's easily capable of sub 3" groups at 50 yards and works well for me in both 9mm and 38 super. I bought a lot of them from OpticsPlanet.
Worth noting that if you order anything from OP, they send you a coupon good for a discount on your next order (I think it's like $10 off a $100 order), so it makes financial sense to not order everything at once.

You know I've never understood the voo-doo with guns and bullets. I've got a 64 that loves Speer GD and a 69, that likes XTP. Heck I've got a Remington 870 that will not shoot a Remington shell, but likes Winchester?!?! LOL

Thanks for doing the research. Nice work.

OP are those the factory loads or your own and if the latter with what powder?
I've been playing with these bullets also as they're the cheapest and most available 9mm hollowpoints right now by a wide margin.

I used 5.9 gr of HS-6 for use in the longer MP5 barrel and my 9mm carbines for testing.

However, I’ll probably switch to 5.0 gr of Unique to bump up the short barrel velocity a bit, given that it could use a bit more velocity for expansion in the handguns.

I just picked a box of the Sig 124s, just because. $19 at Sportsman’s Warehouse. I’ve had good luck with Sig ammo.

Interesting. I think the sierra data for these gives very conservative charge weights. I was using BE86 and found that their 4.9gr max charge at 1.09 wasn't even giving a clean burn and the spreads were terrible. Much better results in the 5.3-5.5 range which is giving me similar velocities as what you have posted for the short barrel out of my shield, but sierra calls that +P+. I don't think so. They also call 4.4gr of unique a max load.

If that data is for a 9mm 124 gr bullet.................
those are my target starting loads in my C9 3.5" pistol.......
around 1010 fps.

I'm curious as to why Sig makes both a 124gr and 125gr .355" V-Crown bullet? Both seem to be an identical JHP bullet but for the 1gr difference in weight.

It looks like a good bullet for SD loads.

Looked them both up.........

The shape of the Ogive area is the only difference that I see as well as the , tip designs.

Maybe the 125 can be pushed harder, per it's jacket make up ?

The 124 grain projectile is designed for the 9MM cartridge and it's brothers while the 125 grain projectile is contoured for the 357SIG cartridge.

Many of the manufacturers have two offerings in this weight class

All of them work in the 9MM family, but the 357SIG's short neck has a few idiosyncrasies, thus the second ogive shape

Thank you Sir, makes sense now...

In my experience both bullets work well in both calibers...

Agreed. That was one of my major issues with the .400 Cor-Bon (a .45 ACP necked down to .40). The short neck complicated things a lot.

That wildcat sounds interresting but I don't want to ask any questions.......
and get my hand "Bugger" for going off topic.
Later.
