Zeroing quick

[Gerry939]

I'm shooting at 1000 yd I'm doing o.k. we have to move forward to 800 yd , i haven't shot at 800 yd before so i don't have the settings in my book, what is the best way to get on target quickest, is it to dial down and by how much, or is to hold off.
am i making myself clear....???

You could use a balistic calculator like Strelok to calculate it but you'd need the BC of your ammo and an idea of it's velocity.

Jimmy is right, you could use Strelock (as I do) but you need gun, scope, ammo and bullet details before it can help you. You can SWAG (scientific wild arse guess) it, or search for your ammo and bullet drop at that distance on google.

My trusty A J Parker wind calculator has a table on the back for just such an emergency! 1000 to 800 yards, 13.5 minutes. This is for 7.62mm, but it should get you on the paper.

If you want an accurate response then you'll need to give adequate information. What calibre are you shooting? What mass bullet are you using? What is the muzzle velocity of your ammunition?

I use a Kestrel with Atrag ballistics calculator that gives a firing solution based on numerous factors including coriolis. But as has been said you need to file quite a lot of data about zero, rifling twist, bullet weight and BC, fps, height of sight above the barrel etc. etc. Once you have done this you can refer to a Range Card that will give you corrections for every 50 yards or metres. Not sure if the Kestrel is the best ballistic calculator but it easily gets you on target at differing ranges and has many other uses such as measuring wind speed and direction and using that in the calculation for a specific target distance.
