It seems to me that some don't take into consideration the difference in a cow elk or Eland and a bull elk or Eland. That difference can be as roughly much as 600 or more pounds on the high end on elk and possibly more I suspect in a few cases..In Eland the differnce can be probably as much as 1000 or more pounds perhaps.

That makes a difference in what caliber one should pick perhaps. It does with me..If I draw a cow permit in Bedkys hayfield, I will take my 30-30, or 250 Savage or whatever. If I draw a bull permit in a good area out comes the 338 with either 210 Noslers at 3005 FPS or the 300 gr. Woodleighs at 2500 FPS and I may take both bullet weights as they shoot to the same POI in my gun, I am prepared for whatever is offered...

Just my personal take on the subject and I wouldn't feel undergunned with the old 30-06 with 180 or 200 gr. Noslers.
