looks like your friend needs to practice shooting. i always love bad shot placement equals bigger gun. Having shot a whole bunch of mule deer and white tails with a 243 only thing holding it back is the shooter. 95 gn sst 400 and in was a dead deer. run one of the 105's and watch them flop.
Some people swear by neck shots, but it's not a good bet. Sure, hit the spine, or a major artery / vein, and they're down quick. However, there's a lot of room in there that is not vital. The ribcage is the only sure thing.After watching my friend shoot a bedded mule deer in the neck with a .243 last year and never recovering...Bigger.

Bad shot placement and poor bullet selection are not the guns fault. The 100 grain hornady interlock will make it to the opposite side of a moose so you will be just fine with mule deer. If you put it in the lungs and shoot at standing or bedded deer and run it in the lungs you will have a dead deer quick. I have seen Magnums fail when shot placement is poor.

I've killed scores of deer (whiteys and muleys) and pronghorns with my 243 over the years. Never lost one. IMO, you don't need anything bigger until you get into elk/moose/grizzly territory. Also, muleys aren't any tougher than whitetails. What works for one will work for both.
