I don’t think elk and kudu are all that comparable.
I enjoy hunting both greatly; but I can’t imagine any kudu, anywhere, comparing to hunting elk in a quality unit during September into October. Arizona, New Mexico, Utah, Nevada have incredible early season elk hunting for old, big bulls. Other states do as well, but it’s tougher to find a truly big bull, both body and antlers, than in those four states.
There isn't all that much in common between a 900+ lb bull elk and a 600-700 lb kudu. A mature kudu is built like a 3-5 year old bull elk, but isn’t very similar to an 8-12 year old bull. They’re a lot bigger, more heavily muscled and, as far as I’m concerned, harder to kill.
Nothing compares to hunting elk during the rut. Nothing! I’ve hunted kudu during their rut and it’s nothing like elk in September. Until you’ve called in bulls, had them in close archery range with no shot, it’s difficult to truly grasp how great elk hunting can be. It’s adrenaline charged, exciting no matter how the hunt turns out. Kudu simply can’t compare.
I’ve been fortunate to hunt elk in every western state except Washington and have also hunted them in Alberta & British Columbia. Most of those hunts have been during the rut. Had some fantastic results and eaten lots of tags, often because I let bulls walk that I should have shot. When I retire my dream is to have elk tags in 4-6 states and roam the west from late August until mid-October, chasing big bulls and making memories. Hopefully, I’ll notch a few of those tags along the way.
I’ve never had that thought about a kudu.
