Any ballistic experts out there? I am shooting a Weatherby Sub Moa 223. I shoot 52gr Sierra BT Hp's in front of 27 grs of H4895...my measured muzzle velocity is averaging 3455 fps. I have sighted my gun in for 1.6 " high at 100 yds. I can shoot at 300yds at our range, but can't shoot any further. As luck would have it, I have had a few coyotes this year at 350 etc yardages. What would my drop be at that distance? I have been holding about 9" high and missing them. Ideas? How about 400 yds?
 
At 400 you are 17in low, sighted at 1.6 high at 100. A 300yrd 0 would need to be 3.2in high at 100yards.A 400yrd 0, you need to be 5.9in high at 100, A 300 yard 0, you need 2.1 in high at 100 that will put you 1.88 high at 200,3.3 low at 300, 15.1 low at 400. Hope this helps.
 
sight hight is from center line of bore to center line of scope. A ballistics calculator will get you close. I used one out to 400yds it was with in 2 clicks on my scope but thats 2" at 400yds.

I believe, it would be more like 20+"...especially now that I am looking at these ballistics calculators.
At 350yds, I should hold a foot high.
This summer,I believe I have some long range testing in front of me!
 
If you have time on a shot dialing is nice, so is using mill dots for hold overs. But you still need to know the distance before the shot. Shoot your gun now and figure out your drops. Mine is zeroed at 200 and 7" low at 300 wich is holding on there back.

That seems very close to what I am shooting.
What loads/fps is that? And where does your gun shoot at 350 and 400yds?
 
Its a 53gr v max over 25.5gr of benchmark. 3,100fps 1/9twist 16" barrel.
350yds 12"low
400yds 20" low
With a 200yd zero.
