.223 bullet drop

[TonyS]

Does anyone know where I can find a ballistics chart that shows the drop of .223 45 grain bullets?  From charts I have seen for 50-60 grain bullets (military)it looks like they rise about 1.75 inches over 200 yds then drop to a zero around 350.  But that was for 50-60 grain and I am looking for information on 45 grain (shooting a 1 in 12 twist)


Thanks!

This might give you the information that you are looking for.

If you know the velocity, this may help:

Best ballistics calculator I've used is JBM Ballistics basic Trajectory Calculator.  It has the actual bullets for many makers and has a place to put the BC.  It's not as simple as just the grain weight as the Ballistic Coefficient may be up to several inches difference at range.  My 7mm-08 load with 175 gr. heavyweights almost adds a whole Milliradian to the drop due purely to BC of two different bullets.  Specifically, Nosler Accubond versus Sierra's Gameking.  Without knowing the BC of your bullet, it's really a crap shoot.
