I just started into the 6.5 grendel world. Surprising cartridge and as of Feb. 2012 SAAMI approved this round. Essentially a patent. Soon thereafter Hornady began serious loading with an optimized 123 gr Amax bullet for the grendel. Now Wolf ammo is due out later this year, much less expensive practice or plinking. I was all onboard for the 300 whisper, blackout, aau... The
ballistics are all for the grendel after 50 to 100 yards. For full disclosure I have a few AR 15's in 5.56's and an AR 10 in .308/7.62. For rifle hunting this year , the grendel gets the nod. The main thing is , spend your thoughts before you spend the dollars. Honestly, I don't think youcan choose wrong as long as you get what "You" arrive upon. Have fun and good luck. Mingokid.
