7mm 197gr SMK...anyone heard anything/

I saw on midway that Sierra has a 7mm 197gr Matchking that is "coming soon". Does anyone know know anything about this bullet or when it should be available?
Thanks
James

Damn...I wonder what the twist recommendation on that will be. I know the 183 SMK was 1-8. Couldn't believe it didn't catch on faster.

Website says 1-7.5 twist. G1 BC is 0.780 @ 2300 fps and above 0.765 between 1550 fps and 2300 fps 0.711 @ 1550 fps and below.

Like the 183 SMK it has an additional tipping process to make the points more uniform and improve BC.

Krieger and Bartlein will make them. Krieger charges a few dollars more for a non standard twist and will only make them in a 4 groove. Bartlein will make a 5r. I don't know if they charge more.

Pac-nor also makes a 7" twist in the 5groove. I want to try these bullets myself at some point. The 284win might be a bit underline with that weight, but why not.
