Pretty nice morning so I packed up and headed out to Jakes with the 7-300 win mag and hopes to get on at 1200 and 1400 see how they grouped and confirm zero's etc...
I was not able to get on the 1400 gong today. Wind kicked up a bit more and mirage got worse. I shot 3 times and could never tell where I was hitting so I called it a day. Will try again on a non windy day and hopefully no mirage. I did however drive up to the 1400 gong and noticed all 3 of my bullets in roughly a 12" group a bit low and to the right of the plate. I had 38 MOA dialed so I"m thinking another 1 MOA would get me where I need to be elevation wise. Wind and mirage can be something else.
Took me 2 shots to get on at 1200 with the wind, elevation was spot on at 28 MOA, ended up with 1.75 MOA for the correct wind and then fired a 6.5", 3 shot group prone w/bipod. Was 4.5" of vertical in the group. My best group to date at 1200, pretty stoked, again considering the conditions were not ideal.
Conditions were about a 10 MPH quarter value wind, switching, dying off etc, 50 degrees, 930 ft ASL, 30.3 pressure.
Load is 75.5g H1000 with a 162 Hornady AMAX at 3150fps.
