I have and do
I have a spanish model 1893 in 7MM that works just fine. I understand in it's time it was "The Gun" for use on game in Africa. I have a Russian M44 I'm playing with now for use on deer. Most surplus rifles have the power for hunting, it's the sights and getting it zeroed thats the pain, and finding the right shell. If you reload you can make them shoot just fine for hunting.
