6.5 Grendel versus 6mm ARC for whitetail

[SDguy]

I have lived & hunted the northern states for in excess of 40 years now & cut my teeth hunting large South Dakota Whitetail deer with the 6mm Rem. My experience has been the 100 grain .243 hunting, class bullets leave little or nothing to be desired for deer hunting when put up against 270 win, 7mm-08, 308 win 7 30-06 for example.

I'v had a few seasons under my belt with bolt action 6.5mm Grendel & the 6mm ARC on a mini action rifle with 22" barrels. For my use inside of 300 yards, 6mm Arc leaves little or nothing to be desired. YMMV

I do subscribe to the notion that bullet choice & placement is key with any cartridge.
