[QUOTE="Fiftydriver, post: 326707, member: 10"] I would not recommend the 130 gr Partition for the 277 Allen Magnum. I have found that the parition wall will split when muzzle velocity is over 3300 fps and if impacts are under 300 yards. The 277 AM, based on a necked down and improved 338 Lapua parent case will drive these to 3700 fps easily..... The 140 gr Accubond actually outperforms the Partition at these velocities. Its a mangled mess of lead and copper but with the partition, if you loose the partition barrier, penetration stops cold. The 160 gr Partition would be better but its BC is pretty low. Until Wildcat Bullets get their 169.5 gr ULD RBBT back in production, I recommend the Accubonds or TSX for the 270 AM or 277 AMs. [/QUOTE]
