Sierra/ Sig Sauer 165 gr V Crown 10mm Bullet

[AKbushman68]

 I just picked up some 10mm 165 gr V crown HP's on sale. Wondering if anyone has some experience with this bullet. Loading for a 10mm RIA  F/S 5" barrel. They are a little shorter than I expected @0.565" w cannalure. I have no info on loads for this bullet , Sierra doesn' t list them in manual #5. I have been reloading since 1976, so I can guestimate an appropriate load, using other manuals with an appropriate bullet wt and length. I utilize QL but it's wonky with the 10mm. I'm not going for nuclear. Probably 1200-1250 fps.  Also due my location Longshot, and some of the newer powders are not available to me. But still looking for some suggestions.
Thanks

I picked up some of the V Crowns as new manufacture but a closeout in 40 caliber, 180gr. I loaded them up with a max load of 2400 powder, about 1250'ps, and found the accuracy to be good but bullet performance lacking. The bullets were not near tough enough for that velocity. They literally came apart which isn't always a bad thing. On a jack rabbit at 25 yds it put bunny all over the pasture. It would not make a hunting bullet for anything you intend to eat. Slowed down to about 1150'ps, the bullet worked flawlessly. Being that you have a lighter bullet and more velocity available, don't expect stellar bullet performance. But it's like anything else, don't know if you don't try. Sierra apparently dropped the 40 caliber 180gr V Crowns so there may have been issues with that particular bullet/weight/velocity/performance. You might have to load them down IF you intend to hunt with them. But then you might also be like my little brother who firmly believes penetration is irrelevant if you blow half of one side off. Hope they work great for you.

I know this  a late add to this thread, but for anyone seeing this thread for the first time -  I bought the same bullets recently. When I did not see any load data at Sierra's website I called their 800# to inquire with a ballistics tech.  He explained they no longer post the data online, but he sent me all the 10mm data he had in an email.    It was watermarked do not share so I am not reposting it here,  but it's only a phone call away if you have any of their other 10mm bullets and need info.
