Bullet Drop M193 14.5" Barrel?

[ranger7]

I'm pretty new to ARs. (Mostly handguns until now.) Recently got a Bushmaster M4gery and I'm sighting it in. I don't always have access to longer rifle ranges and sometimes have to be satisfied with a 50 yard pistol range.

I've been searching (and searching) for a table that tells me bullet drop differences for M193 (or XM193 or Q3131A) out of a 14.5 inch barrel. I found MV figures (http://groups.msn.com/TheMarylandAR15ShootersSite/rifleperformance.msnw) but not bullet drop. The type of info I want seems to be available quite a few places for 20 or 24 inch barrels but since the MV out of the 14.5 will be considerably lower, the bullet drop must be different too.

To be sure I'm being clear in what I want - Assume I've zeroed my 14.5" chrome 1 in 9 barrel) AR for 50 yards (or 100 yards). How much higher (or lower) will I have to aim for 50, 100, 200 or 300 yards, assuming I'm shooting M193 ammo?

Prefer a site where this data is located rather than an educated guess.

Thanks in advance.

First of all, let me say that I do not have the information you seek.
However, let me offer you a piece of advice. Do not just randomly pick a range at which to zero. However, the Improved Battlesight Zero just happens to be a 50/200 yard zero. This zero makes best use of the cartridge and the article gives you a very good idea of where your rifle will hit at various ranges. The point of the IBZ is that from 0 - 250 yards, your carbine should hit within +/- 2" from point of aim.
Please read this article on the same website you already accessed: http://groups.msn.com/TheMarylandAR15ShootersSite/improvedbattlesightzero.msnw
This is a well thought out method of utilizing the AR15 carbine or rifle and it doesn't require a different range than the one you are already using.
No matter what method you use to zero, the only exact way to know where your rifle will hit at various ranges is to shoot your rifle at those various ranges. The tables will put you close, but it is not exact. Depending on what you intend to do with your rifle will determine how exact you need to be.
