The one I got from Tim is a little bitty thing. About 2 1/2 inches of cut. I would bet whatever you get from him is going to have more cut and be a little heftier. I don't see any reason to even consider it wouldn't do a couple of elk. I used mine to cut everything that even remotely looked like it needed cutting for a few months and then resharpened to ~15 degrees before deer season. I normally shoot four, but this year I passed on too many early on and didn't like the looks of a few later, so I only had two to cut up. For what it's worth, M4 is not stainless and I did NOTHING to protect the blade and all the has happened is a little patina has started on it.
