You can go check out Remington's site -
http://www.remington.com/ammo/ballistics/ballistics.htm and check a similar bullet weight and velocity, just to get an idea. Using the drop down menu select 25-06 for centerfire (or any other rimfire, centerfire, or shotshell you're interested in) and it'll list Remingtons offerings. It's a good starting point.
I also like it because you can compare different loads of different calibers. Like how my .270's trajectory with Rem express 100 grain psp's compare to a 22-250 55 grain express psp. The long range trajectory shows these two loads with less that an inch difference from 0 to 500 yards. After seeing this, and seeing how my weatherby likes the 100 grain psp's my need for a flat shooting 22-250 dropped alot. A few boxes of ammo are much cheaper than a new shooting rig, scope, ammo, etc that I'd use maybe once a year or once every few years...
