The 105 Amax is superbly accurate in my 1-8 243, but I had one shatter into tiny bits on a behind the shoulder shot on a pronghorn buck at 200 yards.
At Jordan's recommendation I tried the 105 HPBT. Its accuracy is stellar, and it does seem tougher (though it's a sample of only one antelope so far). They're reasonably priced too.
I've pondered building a 6x45 to use up the rest of my Amax bullets.
