“The Bulletsmiths” from Sierra seem to have a new 243 caliber (6 mm) bullet incoming.
Someone, most likely an avid reloader, noticed that Midway USA were listing the new bullet as “in stock soon”.
You can find the link here.
Sierra MatchKing Bullets 243 Caliber, 6mm (243 Diameter) 110 Grain Hollow Point Boat Tail.
What makes this bullet special is its low drag, Sierra claim a G1 Ballistic Coefficient (BC) of 0.617.
There’s no information about G7 BC yet.
Below: high speed, low drag

One difficulty will be to find a “fast” barrel that can stabilize this bullet, the recommended twist rate of 1 in 7″ or faster might not be too common.
If the Ruger Precision Rifle can stabilize it, I guess it will be a popular bullet very soon. RPR’s twist rate is 1 in 7,7″, but the 243 was only available in version 1 which is now discontinued and recently removed from Ruger’s homepage.
