[QUOTE="Fiftydriver, post: 857899, member: 10"] When the Partition was designed, 3000 fps at the muzzle was a pretty serious load, today, that is not the case. Your results at 3000 fps are what I have seen to. Again, anything over this to around 3200 fps you start to see problems come up. Again, this depends on range and type of impact. Soft impacts, less chance of a problem, hard impact, more chance of problem. What happens when the partition cracks is that the rear core is just blown out the rear of the bullet as there is really nothing keeping it in place other then the crimp on the base core which is not overly strong. When the base core is blown out, penetration stops. So, with the partition, if the partition holds solid, good performing bullet, when it ruptures, terrible performance. This is not the fault of the bullet design, again, when it was designed, the chamberings used were a perfect match for its design, today, the design has been far outgrown by the velocity potential of todays chamberings, even commercial chamberings. Not sure what batch of Accubonds you were using that blew up but early 30 cals did have some problems. From what I have learned, the flux compound used in some early lots of bullets caused corrosion between the jacket and core and also caused some tips to dissolve and fall out. IT was reported this problem caused jacket core separation and as a result dramatic bullet weight loss. Since then, I have not heard of any legit issues with the Accubond in any caliber but I fully admit, there were some lots of 30 cal bullets that had serious problems but that problems seems to be well in the past. The A-Max is a great bullet but its not a big game bullet. They work great in lighter big game, pronghorns and lighter deer species, especially at longer ranges but anyone that would intentionally point one into the shoulder of a bull moose really needs to reevaluate their process for choosing a big game bullet.
