I have taken all my deer (2
) with iron sights. We hunt really thick guts and ridges and will push the bush so its rare to see a deer out past 50yrds.
I bought my 1st scoped rifle for this past season and the scope cost me a deer, a doe ran past 15yrds away but I couldn't find her in the scope, if I had my iron-sighted lever I could have unloaded into her.
