[QUOTE="BrentM, post: 1970947, member: 61747"] As others have said internal ballistics are not changed much unless your powder is temp sensitive and on the ragged edge of hot charge. External ballistics is what you will be concerned with. Being a bow hunter, like myself, I'd personally not be attempting anything over 300 since you haven't practiced, don't know your ammo and weapon, and don't have a fundamental understanding of ballistics yet. Just get closer, within 300, and zero your rifle for 200. Shoot paper at 300 and record the drop. Use this info to help hold high on a 300 yard shot or hold dead center on 250 and less. I understand that long range is the rage and everyone wants to be involved but mountain shooting throws wind, up and down drafts, and angle shots into the mix with less than ideal shooting positions. Throw a 10 mph wind, 20 percent slope, and a crappy shooting position and a 500 yard shot becomes a miserable experience. I've guided a lot of hunts that would've gone wrong if I myself didn't spend a ton of time shooting all year in terrain. I don't consider range time practice. [/QUOTE]
