First time shooting this far with the 450, and it was an experience! It shoots fairly flat to 200, but drops like a brick soon after. I was using a Burris Fullfield II 3-9x40 with the ballistic plex reticle. First bar on the reticle worked great at 200, but the second and third were hitting low at 300. The sweet spot was where the crosshairs start widening below the bars.
I hit 8” steel 4 out of 6 times when I figured out the reticle. Actually, I tried my 6.8 SPC first, and it was pretty easy to hit the 300 regularly with it. I’ve read here about the 450’s trajectory, but now I fully understand.
