Find out the best settings for your favourite Gun/Load combination. Just enter a Vital Zone up to 20 inches in diameter or select from the given values.
Example:
Question:
My favourite deer load for the .270 Winchester consists of a 130gn Nosler Solid Base bullet driven at 2950 fps. If we consider a good sized deer to have a vital zone of 6 inches in diameter, out to what range can we shoot this particular game animal without having to compensate for holdover? What sight settings are required to achieve this optimum trajectory?
Answer:
1. Select your deer Gun and Load.
2. Click Calculate on the menu, then Optimise Load.
3. Select the Vital Zone of an average sized deer.
4. Click the Find Optimum Settings button.
Here is an example of the statements that appear :
Set sights to shoot 1.2 inches high at 100 Yards for a 220 Yard Zero.
This means you need to sight-in your gun to have the bullet impacting +1.2 inches high from the bullseye of the target at 100 yards. If you then had the same target at 220 yards, took aim at the bullseye and fired, your shot would come very close to hitting this mark (depending on how good a shot you are).
Point Blank Range is 265 Yards.
Point Blank Range is an extremely important concept for hunters to understand. It simply means the distance at which you can hit a target without having to hold over or aim under. This depends on the vital zone of the game animal.
For example, an average sized deer has a vital zone of 6 inches. SHOOT! calculated a point blank range of 265 yards for your deer Gun/Load. What does this mean? You can be assured of a hit within the vital zone of a deer without having to compensate for holdover all the way out to 265 yards.
