I have tested the Sig V-Crown several times and have been less than impressed with their performance. So it was with some hesitation that I pick up a box of 10mm and .357 sig when I had the opportunity. In fact, after the .357 Magnum test, I had decided to not to try them anymore. But I decided to give them one more chance while at the same time not expecting much.


I got a five-round average velocity of 1189fps with a high of 1205 and a low of 1176fps.



Round one in the Clear gel had a velocity of 1222fps and penetrated to 18 inches. The expansion was .71 inches and a recovered weight of 177.3 grains. Round two's velocity was 1186fps and penetrated to 16.5 inches. The expansion was also .17 inches and the recovered weight was 177.6 grains.



The V-Crowns seem to have problems with the clothing test and wile not a complete failer the results were mixed. The first round's velocity was not recorded with the chronograph. It penetrated to 25 inches with a recovered diameter of .61 inches and weighted 177.8 grains. The velocity of the second round 1206fps and it penetrated to 19.5 inches. Recovered weight was 177.1 grains and the diameter was .65 inches.

Damn, I was hoping these were bonded.

Those are actually better results than I expected. Ivwish they wouldn't over inflate the velocity though. I chronographed the 10mm FMJs and they were coming in 45 fps slower than advertised on average.

@CraigC Underwood Ammo offers legit 10mm loads with Speer Gold dots. I believe those are bonded, correct? I know they can come apart at real high velocities but out of your GP they should be fine I'd think think.

 

[CraigC]

Gold Dots are definitely bonded! I've driven the 180's fast enough to come completely unglued (seems like 1475fps?) but the core always stays bonded to the jacket. Would be a great deer bullet at 10mm velocities.

That doesn't seem like a very big improvement over .40 S&W.

I was very excited when the 10MM came out and we were told that it would be a "Semi-auto .357 magnum." 155 grain bullet at an honest 1400 FPS.

That I would like.

You are correct. Most factory ammo is loaded just above 40 S&W specifications. The worst I ever shot was Ultramax. It was like a popgun. Not sure it was even at 40 velocity. At least the velocity SIG states is close to real world tests.

To get the most you need to handload. My loads with 180 XTP's run around 1300 fps. The extra 100 or so fps makes a difference in bullet performance

You can get real 10mm ammo from Underwood Ammo. There stuff is legit.

Or you can load your own, which is what anyone who shoots 10mm regularly does. My 180 gr loads run about 1225-1250 fps.

Right, that's what I seem to remember you saying awhile back. It's why I won't run them out of my 10mm carbine. I'm looking at solid copper for that beast.
