years ago,i used a chainsaw to split a elk strait down the back bone,it worked pretty good but was a bit messy slinging bone fragments and pieces..nowadays i have been using a cordless sawsall with a long blade,,it does a cleaner job by far,,have 2 batterys available if your gonna split a elk strait down the back bone,,makita has a small sawsall that i use now that is light and handy,,packable for a few miles in easily that i recomend,, also these days with cwd and travel restrictions the saws all is the way to go to elimiminate the back bone and spinal column areas that must be left on site,,alot of the other quarters can travel with bone on,,but check your particular states rules and the ones your traveling thru.
