Well, thats pretty open.....

Do you have an idea about what style and make of bullet you want to use, which powder, what loads and pressures, and not to mention your particular rifle's barrel length ie is it a shorten sporter?
 
Also are talking reload ammo or commercial ammo?
 
Both Lee and RCBS have some pretty cool software, that can plot ballistics curves for damm near ever combo Dave could ever think up, as it has over 35,000 load combos.
 
Especially RCBS' new software as it also assist in the designing of improved cases and any wildcat.  
 
It's called RCBS. Load, there's a video clip here
 
If you don't like that route, most of the commercial ammo Manf. have a certain amount of ballistic data on there websites
 
this is the data federal lists on it power shok ammo
