I've recently started using the 123 grain Eld-m in my Creedmoor for both deer and foxes and have shot several hundred in that time. In my opinion,they're the perfect compromise between a varmint bullet for foxes,and an out and out hunting bullet for deer. The bullet jacket on the Eld-m range of bullets are thinner from the meplat,all the way down from the ogive to the base,which is also thinner. That's from Hornady published data. They perform very well on deer,neither blowing massive hole's in them,or having deer run a long way before dying. On foxes they are not as devastating as a pure varmint bullet,but perform much better than a bullet designed for deer. So,in short,the perfect compromise for someone who wants a bullet for both,and that includes me as a Gamekeeper. If you only shoot deer,they are definitely worth a look.
