I'm new to all this and have new equipment that I'm attempting to get working together. I have a 338LM, a G7 NF scope, and a B7 LRF. I still using factory HSM 300 gr VLDs, reloading is this winter's project...
Previously I was hitting consistently 2 - 3 feet high at 1300 yards so I adjusted the muzzle velocity in the G7 to correct, of course I first reduced muzzle velocity just to confuse myself, and ended up adjusting the FPS from 2780 to 2840 once I figured out the correct direction of adjustment.
With the light going fast and the wind going from a measured nothing to 5 mph I fired the last 3 rounds. Obviously I did not read the breeze correctly with a horizontal spread of 18". But the vertical spread, including the third shot in the dirt beside the plate, was about 6''.
I believe I can get the yardage, dial in a correction and be very close vertically. However, with winds 0 - 5 which is about as good of conditions as one can hope for, I was disappointed in the horizontal spread. I was shooting prone with bipods.
Any suggestions or pointers?
