ok im not that smart about this stuff yet but I am looking for some ballistic info on Federal XM193 55g FMJ and if possible Wolf 55g fmj and hp.

From what I am figuring out I should sight my rifle with the xm193 which I shoot most of the time at the first crossover in the line of sight. and should be good till the second crossover out to around 250-300 meters.
am I correct in assuming this

Unless there is a link to this info can someone help me out here...

I use XM193 and QM3131A for the precision and wolf for fun blasting out of my Bushmaster 25th AC.

any thoughts

First off you need to visit:
[url]http://groups.msn.com/TheMarylandAR15ShootersSite/zeroingmethods.msnw[/url]

Once there you need to read LTC Santose's article on the Improved Battlesight Zero.  A method where you zero at 50 yards for a far zero of 200M.

Also if look carefully on the page (or check the menu bar on the left) you will see a page with graphs of the trajectories with various rounds, barrel lengths & zeroing methods.

After that if you have any questions stop by here.
