New to Rifles - Help
Sorry if this posts twice....I tried posting once, and for some reason I can't see it.
I've been trying to zero in my rifle (Ruger 308) shooting 150 grain FMJ. I'm shooting a group at 100 yards around 2" high which is where I beleive the bullet should be at that range. However, at 200 yards I am consitantly 4" high. I would expected at two hundred yards to be zeroed.
I have two thoughts:
1- I am at an elevation 5,200 feet above sea level. Is this causing the bullet to have less drop than what I am expecting?
2- The targets at the range climb up a gradual slope at 100 yard intervals. The 200 yard target is higher than where I am shooting. Would this effect the point of impact by 4"?
Any help would be appreciated.
