Default Any charts are graphs out there for 9mm carbine 16" barrel 115gr out there?

I've read tons asking for the same info but I haven't seen much. So far seems like zero-ing at 25 yrds seems to be the best for 25 50 and 100 yard targets. I'm sure it's been asked only like 999,999,999 times so now it's 1,000,000,000

Are you looking for a chart that shows bullet drop over a certain distance?

Thats different for everyones rifle. Depends on the height of your sights, velocity of the bullets and the distance your zeroed at.

I have Strelok and have some numbers for 124gr out of a 16" barrel going 1300fps, if that helps.
What do you want to know?

The Ballistics by the Inch website has useful velocities if you donít have access to a chronograph- http://www.ballisticsbytheinch.com/9luger.html

Pick a bullet weight, use the velocities from the BBTI website, measure your height over bore, pick a zero distance, and plug the numbers into any online free ballistics calculator (i like Hornadyís) and youíll have an estimate for bullet drop.

Something like this site would be cool but since I didn't find it I'm sure there isn't this extensive of charts out there. I'll check out the ballistic calculators thanks guys.

A lot of free online ballistics calculators give charts exactly like that. You just need to plug the values in.

That Ballistic Coefficient doesn't look right.

I didn't know what that was till you just said it and I looked it up. I think it's more like .15

That sounds right. Although at pistol caliber distances, it likely won't matter much.
I zero for 75 yards since it shoots flat (within 2.5") out to 100 yards.

Here are my velocities from a 16" Colt Pattern PSA, 129 different factory rounds.

Enter the BC of the bullet, combine the velocities... and you should have a pretty danged good idea of the basic drop of the 9x19 round.... it is pretty similar to a 22LR round from a 10/22

That is an excellent thread. Thanks, bfoosh006!

How do you find the ballistic coefficient of the bullet? Many manufacturers do not publish it, or my google-fu is failing.

BTW, what is "ES"?

Hornady usually shows BC's for their reloading components.

Looks like I was off by 100th for the coefficient. I imagine with 9mm over 100 yards that shouldn't change things too much. Thanks for posting that bfoosh006
