There's no standard because no one has posted a field chart of avg dispersion @ XXXyrds. The
[email protected] is the best resource extant, and that would say a 4x6" group at 200yrds is your best expectation.
(We did the math and put up our 1" lollipops @ 200, we figured with the avg dispersion of SK rifle match, Best case was 35% hits with a perfect shooter. Best score of the day (33 shooters, 46 attempts) 3/10.
If were were to take the ratio of dispersal....(or rather the decay of accuracy) and come up with an equation that provided
Approximate numbers; Then, and only then, could we begin to standardize targets based on whats possible in real world conditions.
But we don't so do a little guess work based on the the following:
1.
determine your shooter disposition.
-Voodoo shooters with $5k scopes and a sponsorship for Center-X?
-Casual long range shooters with a nicer than usual rifle and some SK?
-
First timers with a 10/22, a pocket full of thunderbolts, and a dream!
2.
What's your wind like!?
-Imagine your match is a bench match where all the rifles shoot .001moa: then ask yourself,
"how much spread does my range induce?" Honestly asses your wind and its effects on dispersion!
3.
MOA
-Do the math! take your target demographic
X, and your wind situation
Y then make yourself a little
X+Y=Approximate Target size in MOA
---------------------------------------------------------------------
Add a few angles to that:
-cold shots
-range finding
-"Gambler" targets (as mentioned by Topstrap)
- Some Odd shapes (Same area in square inches, different or offset center of mass, Off axis lay lines, etc.
And you have really solid course of fire.
