I've used it in .30/06 and .300 RUM.
Most accurate big game bullet I've ever used.
My .300RUM throws them at 3,050fps into 3-shot 1/2" groups over 90.0gr of Reloader25.
Not exactly a rifle/cartridge you spend a day at the range "blasting" with. (savage M110 w/26"bbl). But a serious hunting cartridge.
In .30/06, it delivers a superior punch. My 24"bbl Colt Lt.Rifle in '06 shoots them into a tight clusters at 100yds. I use RL22 for 2,600fps. At 10,000' elevation, it's astonishing how flat these bullets fly! I use them to hunt elk. Really wasted on anything smaller.
