My experiences with the accubond has been mixed. Agree with the above statement. The accubonds seem to do much better when the mv is 3000-3100 or less...again, in my experience, especially on tougher game..the jacket it too thin for the higher velocity calibers such at the RUMs and the newer 26 and 28 Noslers...not good penetration was my experience when used in Africa and here in Montana. Especially on game like elk out of my 300RUM and 7mmRUM...

They work well with more moderate velocities such as a 270, 280, or heavier for caliber bullet weights to keep the speeds down..
