For quite some time I have been looking into building a custom hunting AR-15 for medium sized game (coyotes/pigs). I am looking for a caliber capable of making accurate shots out to 500 yards (if I do my part), and is preferably flat shooting. I will likely be shooting the Barnes TSX/TTSX bullets or the Hornady GMX bullets and I do reload. Unfortunately I cannot seem to make up my mind as to which caliber to choose.I would very much appreciate any comments or suggestions for a specific caliber (pro's/cons etc...)I have been looking at the 6.5 Grendel, 6mm AR Turbo, or the 243/25 wssm from D-Tech. I am having a hard time making my mind up but am narrowing the choices down to either the 6.5 Grendel or 6mm AR Turbo. I have come to those two caliber choices mainly due to brass/bullet availability. The Grendel seems pretty popular but I like the amount of bullet choices available for the 6mm.Ideally I am looking at having a barrel approximately 20" or 22" depending upon how that will affect the ballistics of the caliber I choose. I currently have my lower assembled already and will just need a complete upper.I look forward to hearing everyone's comments/opinions! Thanks in advance for any responses!
