I was able to get out this morning and put my first group up at 600 yards, ever. Prior to this I had been able to shoot only to 400 yards on paper.
Anyhow, here is the info on what I was shooting:
Semi-Custom Model 70 in 270 Win, 24" McGowan Tube in a B&C ultralight medalist stock. I've shot just over .5MOA at 260 and 400 yards with this fairly consistently off a bi-pod.
I am running 57gr of H4831SC under a 140gr Accubond, and am guessing based on drops to be getting 3020FPS with them.
Scope is a Nikon Monarch 4-16x42SF in Talley rings/bases. I used Nikon's Spot On program to calculate the dope seen on the target. I have it zeroed at 270 yards, and dialed up 32 clicks and right 9.
Environmental inputs: 7200', 75% humidity, 55 degrees, 30.19 in. pressure, Wind 5-15 from the SE.
As this is my first group at this distance, just looking for any input or suggestions get my groups down in size.
Thanks for any help fellas, and that sure was fun! I think I will be getting out to shoot this far and more, more and more!
