I don't think you NEED another scope the 1.5X4 will do nicely to about 200yds. I think most of us are over scoped.
I have 2.5X8 Leupy's on all three of my calling rifles. I am considering putting a 1X4 Or 1.5X6 on one of them.
I'm hunting woods and field edges. A 300 yard shot would be a Loooooong poke for me. Most of my shots are 100yds or less.
Consider how far you are realistically gonna shoot.
