Just wondering if anyone can help on this. If your shooting a .243 with V-SHOK 55 GRAIN NOSLER BALLISTIC TIP sighted in at 2 inches high at 100 yards what is the trajectory at 25 yards how high or low is the bullet?

The reason I ask is this. I want to sight the rifle at 25 yards to get a two inch high result at 100. This is because Im sighting with a lazer bore sight and at 100 yards I can't see the lazer dot because of the bright southwest sunshine and a dying battery in the bore sighter.
I can go out and buy a battery for the bore sighter or sight the rifle the standard way and use some ammo but just wondering if anyone has a trajectory table or knows answer already.

Thanks All,
 
You're going to have to shoot the gun on target. You can't get away with just using a bore sighter for more than getting the point of impact into the ball park. The differences in height of the scope above the line of the bore, combined with the differences in the whip of the barrel will, among other factors, combine to make relying solely on the bore sighter unrealistically optimistic.
 
southwestwalkers looks like the V-SHOK is suppose to have a muzzle velocity of 3850. So I ran the numbers and it looks like this. Dead on at 25 yards would put your bullet 3.5 inches high at 100 yards. Did you measure the first yardage or is it a guestament? Because a 35 yard zero with the figures for the ammo and bullet put you at a 35 yard zero and 2 inches high at 100 yards. Since your barrel will be different from the barrel used to obtain the factory MV your mileage may vary.
 
The problem with a lazer or any other bore siteing device is that the lazer is a straight line, eye sight is a straight line, but a bullets path is a curve. The factors invloved are line of sight above bore axis, bullet drop at 25 or 35 Yards and at 100 Yards. and the fact that you want two inches high at 100 yards. Best to go to the range and burn some powder. Helps your shooting as well.
