[QUOTE="Wapity hunter, post: 1869824, member: 113367"] I found the nosler long range 150 grn accubonds in .277 cal were all keyholing at 200metres. At 400 75mm group and at 600 metres 300mm group. Plus after 350 meters the drop was way off , 1.5 times more drop. As they were doing 3290 fps I could only assume that tips were melting and deforming after around 300 meters. I changed to the hornady 145 ELDX and long range accuracy returned to what it shd have been at 600 plus meters. Maybe this is what's happening. Just a point to look at. [/QUOTE]
