MR/SR., they use different targets now? My mind goes to the harder line, 600, 10 ring is half the size of the X ring. Thats where it gets tough. If your AMMO won't hold even the X ring life is getting really hard. IIRC you are talking 200-300 yard more foregiving targets. Regardless even there things help.. have you shot a 100-0x like I have.. missed the wind but the knot stayed tight enough?.....

6 inch x ring, 1 moa. 10 ring, measure it, either side of the x ring, its 3 inches to the line, then 3 inches to the edge of 9, 3 to edge of 8, 6 to edge of 7.

So if your ammo shoots 1.5 moa, its using all the x ring, plus one side of the 10 ring., That leaves 3 inches wobble, for you, the gun, calling the wind and light correctly.

Now if your gun is .5 moa, 3 inch group at 600, and you wobble the same, you have shot a 200-20X and not even close to the 10.

The other way around you might shoot a 200 the odds of 20 X ain't happening...
