I have killed 2 animals with the Powermax bullets. Both fired from a 30-06, both 180 grain. An antelope lung shot resulted in a dead antelope but that small an animal and that broadside shot is not a good test of the bullets performance. The mule deer I shot at 25 yards, angle towards me at a steep uphill shot did test the bullet. The shot took him at the shoulder and mashed the spine. The bullet was recovered in horrible condition but what remained was badly mangled but core and jacket did not seperate. I have witness this same shot angle many times in my carerr as a hunter and guide and it is a major bullet destroyer. With this limited use, so far I am impressed, however the jacket is thin thus regulating it to deer sized animals in my opinion.
