I just picked up a 80's something model 94 in 30-30. I plan on starting with the factory sights and may go to a tang or reciever in the future but NO SCOPE. My question is what kind of groups should I be happy with? I have a scoped rifle that I shoot tiny groups with and I don't want to be unhappy with this rifle because I am expecting too much, especially with open sights. I'd like to hear from some of you guys who have a lot of experience with this rifle/cartridge combo. thanks
