| POP: I don't have any data or experience to share but I do remember reading an article several years ago which said that even Partitions will/can come apart if pushed too fast. If I remember correctly the critical speed was 3400 or 3500 fps. |

I wish that I could help but I have limited my use of Nosler partitions to 125 and 140 bullet weights in my 264. I have used the 125 grain bullets at a muzzle velocity of 3,200 fps with great success on small South Texas whitetails and the 140 grain bullets at a muzzle velocity of 3,100 fps on Michigan whitetails, relatively large Colorado mule deer, and black bear.
Ballistics show that both the 125 and 140 bullets are quite flat shooting and retain their downrange velocities better than the 100 grain partition.
I considered the use of these relatively new 100 grain partitions during a planned wolf hunt in Ontario next year, but decided to stick with the proven 125 grain load.
Your loads? (so I can get a general idea) |

| Well POP, I can't verify the performance with a 264 mag, however I can verify the performance with a 100 grain partition.
I shoot them in 260s, 6.5 x 55s, and 6.5 x 57.
In a 22 inch barrel 260, that bullet hits 3350 fps MV consistently. IN a 26 inch barrel it hits 3450 ( Remington 700 VLS).
In a 26 inch 6.5 x 55, and a 28 inch 6.5 x 57 Winchesters, it hits 3500 fps.
When it hits a deer it will go thru it, and do its Partition performance.
As far as velocity, if I can get that out of these smaller cases, you should be able to better that a little with a 264 mag. I am not a mag fan, tho, because of the efficiency of the smaller cases in this bore. However, if you are looking for the bullets performance at this velocity, the answer is ALL DAY LONG.
If asking, my powder of choice is IMR 4064, 43.5 grains in the 260, and 44.4 grains in the 6.5 x 55 and 6.5 x 57. Large rifle primers and bullet seated out as long as I can since all rifle chambers are cut to take the long 160 grain bullets, ( except the Remington VLS). |
