Drama? it's more like a weird ADD conversation, the sort of confusion that arises from someone insisting that an apple is an orange because they're both fruit. The strangest part is that the naysayers have one thing in common, namely, they haven't actually shot an eland. Of course, everyone's entitled to an opinion...
The forum members on this thread who are saying "bring enough gun" have actually had the experience of shooting one and are trying to share their own experience shooting eland. The "surprise" for those hunters came when they executed a shot with the eland facing them head-on.
The observation was "insufficient penetration" on the facing shot. This is not to say that a broadside shot with a .30 cal 180 grain bullet won't kill an eland, it clearly will (look at Neo's eland carcass on the last thread on this subject).
However, during your eland hunt you may find that the eland doesn't want to cooperate and may, in fact, insist on facing you head-on, offering you a whole pile of meat to shoot through before you put that pill into the boiler room. The question then is: can that front part of an eland stop a conventional 180 grain .30 cal bullet from reaching the chest cavity? I'm satisfied that it can.
If you want to use a lesser caliber on your eland, have at 'er. Stick to broadside chest shots though, or it may turn into an expensive learning experience.
P.S. great idea to get familiarized with shooting off sticks and, if I can offer a suggestion, try slinging up if you have the time (it makes shooting off sticks a lot more stable).
P.P.S. - In all fairness, if a guy shoots an eland four times in the chest with 180 grain 30-06 rounds, on a facing head-on shot (as Neo did during our hunt in 2007), you might conclude that the hunter was a poor shot and missed the target. However, if the eland carcass has four wounds none of which reached the chest cavity and only one hole from a broadside shot reaching his vitals, the objective observation is that the first four bullets actually ran out of steam and stopped short of the chest cavity. That isn't poor shooting, it's a demonstration of insufficient power/penetration for what we would normally consider a killing shot on the game we are used to hunting. It isn't opinion, it's an observation of fact.
