[QUOTE="Fiftydriver, post: 483677, member: 10"] Lapua guy, If your shooting a chambering that will have an impact velocity of under 2800 fps, I may agree with you but with the modern magnums, the partition WILL fail 50% of the time when impact velocity is over 2800-2900 fps. When impact velocity is 2900 to 3000 fps partition failure is easily 75%. Over 3000 fps impact velocity, nearly 100%. When I say the partition fails, I am saying that the partition barrier is ruptured and once this happens penetration stops instantly because the rear core of the bullet is generally pushed out of the jacket and penetration stops. In penetration tests, the Accubond will match the partition in penetration and retained weight up to 2800 fps. Above this, the accubond performs MUCH better and much more consistantly and dramatically better at the even higher impact velocities. I have tested this with the Accubond vs. Partition in 6.5mm, 270, 7mm, 30, 338 and 375 calibers. In EVERY test, once impact velocity went above 2800 fps, the Accubond was a far superior penetrator and retained more bullet weight. Add to that, better BC and generally much better accuracy and the partition is an outdated bullet for the modern high performance magnum chambering. I have said it a thousand times that the Accubond will replace the Partition in big magnums and is the best bullet Nolser makes. Again, one would think your opinion is correct but it is not. I thought the same until I put the bullets to actual penetration tests and proved it. [/QUOTE]
