I built a 6.5 Grendel with an 18" Satern barrel using a Bushnell Elite Tactical scope. I've had great results with other bullets, but the 123 grain AMAX bullet is the by far the best bullet ever fired from my rifle. Using Hornady brass and AA 2520 powder, I was shooting the same hole at 100 yards all day long. I decided to join a club with a 300 yard range. My first time out was awesome. A 3 shot group measuring .861". Thank you Hornady for your excellent yet affordable products.
