223 55 grain sighted in ay 100 yd's 16# barrel. Question?About how much drop at 200 yd's and 300 yd's.Knowing this would have made a big differ this last weekend.

Way too many variables to answer you acurately...

Here is why

from a 100y zero with my BM 20"

PMC ammo is about 3" at 200 and about 8" at 300
Q3131A is about 2" at 200 and about 4" at 300
AE is about 2 1/2" at 200
UMC is about 4"  at 200

from my 700 VS with 100 yard zero

PMC is about 3" at 200 and 5" at 300
Q3131 (not A )is about 1" at 200 and about 2 1/2 at 300
UMC is about 5" at 200
Reloads depending on which one I load up vary from 1/4" ( very hot load ) to about 4"

If you knew velocity you could get close info from a balistics chart, but even that will not be 100%

When I shot my first 200 yard match I was still in the black from my 100 yard settings and I general rule of thumb is 3 clicks from 200 yard zero to 300 yards.

hope this helps in some way....[8D]
