[QUOTE="Tac-O, post: 1970567, member: 109994"] It looks like I will be rifle hunting this year, somewhat unexpectedly, and for the first time! I've only ever hunted archery and with a slug gun. . I haven't got out to practice in the field yet, mainly because I've just been learning about my reloading and figured I likely wouldn't rifle hunt at a much higher elevation and potentially longer distance. That being said, I haven't shot my hunting load at high altitude. Because I haven't practiced in the field yet, I need to do so to determine what my max responsible shooting distance will be. I can say that it is definitely not farther than 500 and very likely not farther than 300. We'll see how it goes. Maybe even just 200. Anyway, in preparing for hunting with my hunting load, even if I won't shoot farther than 200, I'd like to know what I should look at with my load in the case that I have a 400 yard shot at 10000 feet at near freezing temperatures. I've been shooting at about 5000 feet My load has been developed at about 90 degrees F, low humidity and highish atmospheric pressure. .30-06 Speer 180gr hot cor H4350 Cci200 I haven't chrono'd this load yet. From what I can find on h4350 temp stability, it looks like there might be a 20fps speed difference going from 90F to 30F, so that is only about 3 inches at 500 yards. So the temperature wouldn't affect my speed enough to worry, especially if I'm limited to 200-300 yards. What about atmospheric pressure and humidity? Would they change the speed more significantly than temperature? Could these two drastically change this load's group size? Next steps: measure velocity, shoot at 200, practice in the field. Thoughts? [/QUOTE]
