What zero for no underhold?

[LordGamebore 0]

Is it true that if I zero my .22 at 20 yards I won't ever need to hold under, just hold over? I keep all my .22 shooting within 30yards anyway.

 

Thanks

There isn't one. Technically as the pellet leaves your barrel it is already slowing down and dropping. The best thing you can do is go out and shoot some targets at different ranges. What you are best to do is compromise a bit. For instance I zero at 25 yards and know that if I am shooting at anywhere between 20 and 30 yards I will be no more than half an inch out.

Lord if you zero your .22 calibre at 20 yards you will be looking at hardly any difference at 10 yards or 30 yards.

 

The speed that the pellets it moving it will cover 10 yards in a point of a second and so not move up or down the sight line by much at all.

 

You are looking at at 10 yards 0.2 inch and at 30 yards 0.9 inch which is well within the kill zone.

hi mate zini is quite right and just so you know if you use a pc there is a software download called chairgun pro from hawke (scopes) that let you work out the ballistics of hundreds of pellets (i use it all the time) they have built in BC (ballistic coefficient) of each pellet because of the weight and you can even use comparison to see the difference of 2 pellets zerod at different distances to see your drop off the link is here

 

http://www.chairgun.com/

 

it is full of great printable info like cap inserts and working out mildot drop at certain ranges even using your mil dot as a range finder

 

hope it helps

I had a look at the chair gun progarame and no doubt its right but surely the best way to work out the trajectory of your rifle is to pick a nice calm day and go out and shoot some targets at different ranges and then you will be able to find out how much your pellet rises and falls at different ranges and you will know its right. Whats the point in this chair gun thing then?

[othickman 6]

Because it is very accurate (apparently) and does not require you to have to wait for a nice calm day, and even if it is calm you'll still get human error..

my s400 is zeroed at 30 yrds and has half a mil dot hold under at 15 yrd and half a mildot hold over at 40 yrds. i shold think that if you maybe zeroed it at 15 yrds then you would only have hold over.

Aaron, the lad's shooting a .22, you use a .177. 'i shold think' is not really sound advice, is it?

You need a calm day to zero properly anyway and you are always going to get human error whatever you do. I don't see how a computer can do a better job of working out the trajectory of a rifle than I (or anyone else) can by going out and shooting targets at different ranges.

I agree mate but I think they are just pointing out its another tool to use or whatever

 

All the best
