Trying to figure out my M1A rear sight adjustment for 200 yards using a 50 yard data point.
Firing a 30 cal M1A SOCOM (16"), making just shy of 2400 fps, using 168 gr SMK in front of 42.0 gr of 4064.
At 50 yards, holding 6 o'clock on a 7" ring, I'm getting a consistent group 2.5" below the bottom of the ring, equating to 6" below center on the 7" ring at 50 yards.
Wanting to hold 6 o'clock on a 7" ring at 200 yards, and hit center, what adjustment do I need on my elevation knob?
Note - I'm also posing this question on the CMP site, but wanted to start with you experts.
Thank you!
