Well, if you like the Sig V-Crowns, Sierra just blogged that they are making them available to reloads - https://sierrabullets.wordpress.com/2015/11/02/sierra-bullets-partners-with-sig-sauer-for-new-bullet-line/.
No 180 grain in 10mm. That is too bad.
I imagine all of these are weights not offered in their ammo line. Double dipping!
I would imagine some type of timeframe exclusive, but my money is on eventually that will see a full lineup. Just a guess though!
