Do you know anything about 30-06 ballistics?
I was wondering about sighting in my Savage. I would like to see a graph so I can figure out where to sight in at 100 yards so that it would still be useful at 200 yds. I do not have a scope on it (I'm an iron sights kinda guy) so 200 yards is as far as I would even think about a shot.
Remington's web site has good ballistics.
For serious North American hunting, I shoot 180 grain bullets from my .30/06s (Springield 03 and Mannlicher-Shoenhaur) and 150 grain bullets from my .308 Winchesters (Savage Scout and Savage 99), so they all print just about on top of each other. The pigs and mule deer don't seem to care which hits them.
For fun hunting, (coyotes) or for meat, I use 180 grain bullets one of my two old .30/40 Krag-Jorgensens. Less recoil, and it kicks the pins out from under anything just fine.
Your mileage may vary.
Depends on such influences as the length of your barrel and the weight of the bullet you use. But this should give you some idea:
| CARTRIDGE | BULLET*(grains) | VELOCITY (FPS) (ENERGY [ft.lbs.]) | TRAJECTORY (200-yd. zero) | ||||||
|---|---|---|---|---|---|---|---|---|---|
| Muzzle | 100 | 200 | 300 | 400 | 100 | 300 | 400 | ||
| .30-06 | 150 | 2910 (2820) | 2671 (2375) | 2444 (1989) | 2230 (1656) | 2030 (1373) | +1.7 | -7.6 | -22.1 |
| .30-06 | 165 | 2800 (2873) | 2573 (2426) | 2357 (2036) | 2151 (1696) | 1956 (1402) | +2.2 | -8.4 | -24.4 |
| .30-06 | 180 | 2700 (2910) | 2470 (2440) | 2250 (2020) | 2040 (1670) | 1850 (1360) | +2.4 | -9.3 | -27.0 |
| *Loads use "standard" bullets and are neither the most nor the least aerodynamic available in weight or caliber. Use of boattails and/or premium lines like Remington Extended Range, Winchester Supreme Silvertip and Federal Premium with Sierra boattails significantly affects ballistics and, depending on the cartridge chosen, would significantly narrow or widen any gaps. |

I would imagine most any ammo manufacturer's web site would have trajectory info. I know Federal does.
It would appear that as a rule of thumb you should be shooting about two inches high at 100 yards to be "zeroed" at 200 yards.
