Just in from the range...

270 Win Kimber MT 22.5" Barrel
RL26
Federal Virgin Brass
Fed 210 M
150 Nosler Partition
3.297" OAL / .020" Off Lands

3 Qty @ 59.5 = 3,051 fps. Extraction ok. 1.670" Group
3 Qty @ 60.0 = 3,093 fps. Extraction getting stiffer. 1.930" Group.
I Had another 3 Qty loaded at 60.5 but didn't fire them.

I plan on backing off to 58.0, 58.5, and 59.0 and see what results I get. If something looks promising I'll play with seating depth.

Certainly seems to be a quick powder with the 150's... speed alone without accuracy holds no appeal to me, but if I can run at 2,950+ with good accuracy I'd be pleased.

More later...
