I put together a Antelope rifle specifically for that.
Caliber 6.5 Grendel
24 inch barrel, I recessed the crown more than normal, mounted the barrel on a DPMS heavy wall upper, Geisely trigger, looking at Nosler 120 grain Ballistic tips for longer shots, I cant seem to find a good powder that lets me load the Barnes TTSX 120's I use in my 6.5x55. I have used Hornandy Amax, but the performance on deer I have shot at 300 yards was disappointing, almost never and exit hole
I mounted a Burris Eliminator 3 aswell.
any suggestions on a good bullet?
I hunt Wyoming and average shot it 300- 600 yards on the plateau
