On a couple of threads down I posted this.
This was in response to the question of 10.5 in barrel zero.
nI wrote the following:
I agree with 100 meters.
if you zero at 100 meters then the following:
M-193 ball = 4 inch target area out to 150 meters.
M-855 ball =4.2 inch target area out to 150 meters.
also if you zero the M193 ball @ 250ms you have +9.9 inch at 200ms, -15.1 at 300.
and for the M855 ball with 300 meter zero, = a +12.6 inches @ 150+
I'd do the 100 meter zero
But in response to your question ,Yes, 200 meters would be much like a "point blank zero". Used in hunting circles it refers to the zero distance that allows the shooter to engage a "target" with out hold off. If you can achieve that with a 200 meter zero then do it. but as you stated that's a 12 inch circle at 300 meters.
You might tighten that circle at about 175 meters to around 9.5 inches.
Let us know when you do, good luck Blitz
The strongest reason for the people to retain the right to keep and bear arms is, as a last resort, to protect themselves against tyranny in government.
To compel a man to subsidize with his taxes the propagation of ideas which he disbelieves and abhors is sinful and tyrannical.
