[QUOTE="eshell, post: 237046, member: 5747"] Actually, temperature can have a much greater influence than just muzzle velocity, which will depend on the cartridge temperature and the sensitivity of the particular powder to temperature changes. Even if muzzle velocity remains constant, temperature affects air density, which affects drag and thus trajectory. I can see swings of 1.5 MOA at 1,000 yards with my 6.5-284 due to changes in density altitude alone. [/QUOTE]
