As the owner of two 300 RUM's and a 338 Win Mag., I will say that for elk where I hunt, in the heavy timber, the 338 is a far superior round. The 338 will reach out as just far as the 300 rum, you just got to know the trajectory. It doesnt matter what you shoot, at 500+ yards all cartridges fall like a rock. The bullet drop is a known, it is consistent as long as you have consistent loads. If you know the range and dial your turret to match the range, it is no different than shooting 100 yards. The unkown factor is wind, wind might be calm where you are sitting and blowing 400 yards down range, that is where a heavier bullet will effected less. That is why I perfer the 338 over the 30 caliber.
