Although your bullet was found in the vicinity of the civil war battlefield at New Hope Church, it appears to be a Model-1882 Maynard bullet. See the photo below, showing several Model-1882 Maynard varieties and calibers. You said yours is "a little bigger than the size of a crayon head" -- but there are thick crayons and thin crayons, so I cannot even guess which one of the Maynard varieties in the photo your bullet may be.
Since you are digging bullets, which you want ID-help for, I suggest you buy a Digital Caliper for making accurate measurement of a bullet's diameter, which is crucial information for correctly identifying the bullet. A good-quality Digital Caliper can be bought on Ebay or at Home Depot and Harbor Freight tool-stores for about $15. See the bullet diameter-measuring photo, below.
Also, I have to mention that due to the lack of lead-oxide "patina" on your bullet, it might be a 20th-Century cast lead bullet, for blackpowder shooters and cartridge-reloaders. For example, compare your bullet with #319050 and 323061 in the sales catalog of modern-made cast lead bullets at the following website:
Ol' Buffalo Bullet Mold Tables
Note, the first three digits of the catalog item-numbers is the bullet's diameter (for example, #319050 is .319-inch in diameter). If your bullet's diameter is larger than that, it is more likely to be an original (not reproduction) Model-1882 Maynard bullet.
