You better check your local hunting laws, first. There might be restrictions on smaller calibres for deer?
If you use a 243 for deer, it should be the heaviest bullet weight you can buy (used to be 100gr and in a soft point), so it will stay together upon impact and go deep enough inside the vitals. A light grain bullet could break apart at the surface of a deer. Especially if it is a close shot and travelling at high velocity loads.
I would use a gun and calibre just meant for deer, only. Many people have more than one deer gun, based upon the territory they will be hunting and the distance of the average shot.
