I have a Mossberg patriot in 6.5 creedmoor with scope. Can I set the scope for 50 yards? I know it's for longer range but I only shoot 50 to 75 yards. will I be missing if I shoot at say 100 yards? What is the drop on this particular round?
 
A lot will depend on how high your scope is mounted. You can zero it at 10 yards if you wish. 50 yard zero will be close at 100. A 25 yard zero will probably be 2" high at 100 and zeroed at 200. It just all depends on how high the scope is mounted.
 
If you shoot mostly at 50-75 yards then zero at that range. A 100 yard zero is a good place to start though and what I like even if shooting at closer ranges. If you zero about 1/2" low at 50 yards you'll be close enough to a 100 yard zero.

If you do with most cartridges your bullet will never be more than 1" below, or above your cross hairs between the muzzle and out to 130ish yards. They will be around 2" low at 200 yards and within 8-10" low at 300. Close enough to need very little if any holdover out to 300 yards. The trajectories on most common rounds is surprisingly close. Most will be within 2-4" of each other out to 500 yards.

Years ago it was common to zero 2-3" high at 100 yards. This would mean you'd be about 12" low at 400 instead of 20" with a 100 yard zero. It also meant you'd be 4-5" high at around 200 and could easily shoot over a game animal. Most shooters today stay with a 100 yard zero and use range finders and scopes with multiple aiming points to shoot farther than 300. Plus, if someone can figure out how to make hits with 12" holdover 20" isn't any more difficult.

How high the scope is mounted will have a very minimal effect on trajectory unless you are talking about the extremes. Most scopes and mounts on hunting rifles will place the scope within a fraction of an inch of 1.5" above the bore. ARs and some target rifles will be 2.5" or more. Then it becomes a factor that needs to be addressed.
 
JBM Ballistics website is your friend. You can get trajectory for any combination you wish and print it out for future reference.
 
You can also download the Strelok app to your phone.
Has many different scope reticles, so you could theoretically see what the target looks like through your scope at different power levels.
Has temp/ weather matching. Also if you sight in for say 120gr bullet, you can add a 140 gr and have the difference in the app for point of impact.

They have a free version, which i started out with, and a "pro" version( $5).
