I only ran into it with a Winchester Model 70 in 7mm Rem mag. I had it happen at least three times. All at ranges of 75 yards or less. I realize that those conditions are tough on any bullet. I continue to use the Ballistic tip in the 25-06, 6.5x55, 280 and 308. Nothing has ever survived or even went more than 10 yards or so after a hit from the 308 at just over 2700 fps. So far I have just used the 150 grain in the 308 but next fall I think I will try the 165 grain. I am going to hunt moose with it next fall. Do you think from your expierence that the 180 Ballistic tip would be better for Moose?
