Well I have a Colt 9mm AR with 16" barrel and Aimpoint PRO on it. For ammo I have a few hundred rounds of Winchester Ranger RA9TA 127grn +P+ that I would like to dedicate for it. Anybody have a ballistics calculator that can find sight in distances?
 
Check Chuck Hawk's sight. He has answers for most ballistic questions
I found this.Should give you some starting point
From ,haha,I was gunna say to go here too
AR15.com
115gr from 8.5" AR @ 1250 fps, Hornady chart shows 6.3" drop @ 100yd with a 50yd zero, 8" drop with 25yd zero.

147gr from 8.5" AR @ 950 fps, Hornady chart shows 9.6" drop at 100yd with a 50yd zero, 13" drop with a 25yd zero.
And the link to a on line calculator

SO on AR15 some are saying 25 yards and some 50.
http://www.ar15.com/archive/topic.html?b=3&f=15&t=465858
If'n it was me,I would shoot the thing at 50 and 100 yards and see what your POA to POI is. I have shot 9s out to 100 yards with a hand gun and the drop ain't that much.Like medic said check your gun,YMMV
They also talk about the effective range of the caliber. Is it for self defense or competition?
For self defense,I would sight it in at 25-30 yards ,cause that would get you where you want to be .
For competition,you would sight it in for the medium range you will be shooting

RA9TA from a 4 inch barrel was chronographed 1250 fps at the muzzle.
Ballistics by the inch 9mm Luger chart
124 gr 9mm bullets exit from a 16 inch barrel 187fps faster = 1437 fps

Gundata Trajectory calculator provides chart and explanation.
Using the calculator, and 1437 fps, and a 100 yd zero, bullet drops 50 inches at 250 yards.

This is a SWAG, maybe close.

Thanks for the help so far. I need to get to the range with someone that has a chronograph I guess. I'm wondering what a 50' zero would do for me? That's what the local indoor range is.
 
I think for you Mjbskwin one of the large frame AR/Glock lowers will better option. You can use the same mags between the G20 and the AR buy the down side is the cost of the lower. I use modified Grease Gun mags and if I had to do a second AR in 10mm I'll go with 45ACP Uzi mags that costs more than the current mags I'm using.

So the the OP why not start at 50 yards and work your way out? I think getting to 100 yards with good grouping should be the goal. Also do you have access to a wooded area that you can use one of the bouncing targets? To me they make a great learning tool.
 
For a good learning target you may like to look at getting a "Reactive Target" for training. Know what the drop should be will help but putting rounds down range at different ranges to me is even better.


And for 22lr
 
I'm adding a few links for you.

The Mech Tech upper with a complete Glock lower from Gunbroker ($150-250) is a option to have most of the same control location as your pistol.
Now if someone would make a 30rnd mag for 10mm.The 45 is out there but needs new follower and feed lips
Thanks for the links
