Went to the range yesterday and did some ladder tests with Hornady's 70 grain GMX bullet. The test were nothing short of terrible. Interested in hearing opinions on where to go next. I'm not hooked on this bullet so if the weight of the advice is leave it and move on...so be it. The rifle used in this test does very well with 65 grain SGK's.
