Gentlemen, from a Hunter's view the Whietail will never know the difference between a 120,130,140 grain bullet well placed by either one. To imagine that a 100 + years ago a group of rifle loonies decided that a 6.5 was a great bullet was sheer genious! I have a 6.5x55 that loves 120 grain Barnes TSX. The deer seem to loathe the combination and my shoulder says, "thats all you got for recoil." Splendid firearm and caliber. By the way I could be just as pleased with a .260. The Whitetails don't know the difference. Buckfever1
