I seem to recall one or more threads a few years back indicating that the 70 grain GMX bullet was prone to shedding petals against some types of target(auto windshield glass, game animals IIRC), problem which did not/does not supposedly afflict the 55gr version. Have done several searches, but can't find said thread/s. Am curious about anyone's recent (say last two years) experience with the 70 gr GMX and whether that bullet is or isn't displaying that tendency.
