I wouldn't hunt deer with that. I know I know, thousands of deer have been downed with the 24 cal. But thousands have ran off too.
Having been deer hunting since 1984, man I have seen it all. God I have been at this for some time now. Heard all the stories. Bottom line is why fool around. If you are going to shoot deer, man do it with a bulldozer round. 35 Whelen, if you are in the bean fields, a 300 win mag, if like me in the palmatto Mississippi river delta, either a 44 mag or a Browning shotgun rifled barrel slug gun. You want to get it over with with a hard hit bulldozer round. It doesn't matter if uncle Joe killed 12 with the trusty Ol 243. Uncle Joe was lucky none crawled off. Having been at it for decades, I say why play around. You should see those 150 grain Magnus Stinger arrowheads do a number. They fold up in sight.
