Re: Nitrex TR Two EBX Retical help?????
Nitrex doesn't provide any really useful information...even if they did it wouldn't be accurate for different loads and bullets anyway, so you will have to figure it out yourself.
Set up a yardstick or make up some type of graphic target on graph paper at 100 yards and take notes of your reticle subtensions.
As long as it is at least 36" tall and marked off in inches you will be able to figure out the spacing.
The spacing will vary at different powers, so make notes of those variations as well.
You will also need to know the true muzzle velocity of your load.
Once you know these details you can compare it to a trajectory chart from JBM Ballistics and create your range card.
