After hunting the last month exclusively with my Grandpa’s old iron-sighted Winchester 94 in 30/30, it is now my opinion that such a rifle is really only effective to about 50, maybe 75 yds max in the woods and maybe out to 100 or so in open terrain. You can certainly “hit” farther than that, but I don’t believe guarantee a clean kill.
I’ve always hunted with scoped rifles so this is new territory for me. I was successful in taking a buck with this rifle at about 40yds, but passed on several other deer at the 100+ mark.
