I have only used it in the 270, The 130 grain. I just can't say enough good things about their accuracy and performance on Mule deer. To start with, they shot under one inch in my 700 ADL Synthetic Remington rifle. Thats three shot 100 yard groups. I hit nine Mule deer and none went anywhere. All the bullets exited doing good damage BUT NOT excessive damage as the 270 can do. I will never use anything else in that rifle again even though I shoot 99 percent reloads. I now have picked up some 150 grainers for my 308 and if they shoot like the 270 did, I will retire my 308 dies as well. I was impressed to say the least. A Nieghbor had simular performance from them in his 243 BLR. I think they were 95 grain but I am not sure. I will try them in the new 270 WSM as well although so far they are only available in the 150 grain for that gun.
