Going on first caribou hunt in early September west of Lake Iliamna area. Have several general questions: 1) in that area what time does the sun rise and set? 2) regarding caribou movements, do they move all day long or is early and late in the day better for hunting? 3) will be uning my Remington 700 in 30-06 and not sure what a good bullet would be to shoot? Know I would be better with a heavier/stronger bullet than used to shooting for whitetail deer here in Missouri, (no bears here).
