I have a 6mm Remington that I had built as a coyote rig that I am considering taking with me on an Antelope hunt this fall. It consistently shoots in the .3's at 100 yards and I have shot 4" five shot groups with this gun at 550 yards. (I guess I am saying it shoots) My question for you guys is as follows; -What would you limit shot distance to on antelope with this caliber? -What bullets would you suggest? It loves the sierra 70 SMK (my coyote bullet) I was considering trying a sierra 85 game king. From my experience with the 87 vmax, It should push the 85 sierra about 3400 fps. Looking for suggestions/experience from you guys. Thanks.
