I just bought an AR and I haven't shot it much, and I'm trying to get an idea of what kind of bullets to use. I will obviously be using the gun for coyote and varmint hunting, and it has an 18" barrel and 1:9 twist. I figured that I probably shouldn't go any heavier than 60 grains or so. I figured that I would try Nosler, Hornady, and Sierra bullets and no lighter than 55 grains. Any recommendations on what bullet weight to use? Also, could anyone give me some ballistics charts or graphs? I'm still not sure whether I will zero the rifle at 100 yards or 200 yards. Would the ballistics change considerably from bullet to bullet? Or can I expect that all bullets of the same weight will have very similar ballistics?
Thanks,
Matt
