I stay away from all Barnes bullets. I witnessed the older Barnes X-bullet fail to expand on a doe antelope out of a 25-06 Remington in Raton, New Mexico. The doe was recovered, but the bullet travelled full length entering the chest and nicked the tail on exit.
I hand load 120 grain Nosler Partitions for my friends Weatherby Vanguard in 257 Weatherby Magnum, I cannot think of a better bullet for this cartridge.
