When did the 300 win mag get in the 338 win mag class of trajectory I'm a bit confused here? Not everyone shoots the biggest bullet they can out of a 300 win mag. For example a 338 win mag can't even begin to compare to a 300 win mag shooting 165 gr bullets trajectory wise not even close. Especially when comments come about long range shooting beyond 400yds. Sure the 338 has a bit more power but at 500yd heavy vs speed, speed is catching up quick and the smaller bullet can compete for ft lbs at that range and in some cases win the battle. If the equation was under 400 yds for all topics why not just step up to the 375 h&h or a .416 and really thump them. Apples to Oranges.
