RE: The old debate
I read this a little different from the others.
First I don't think this is an iron sight vs. scope problem/issue. Both are effective. Both have advantages as well as disadvantages.
Scope advantagesare pretty easy, distance, more light in low light conditions, less technical to shoot for a beginner.
Scope disadvantages are wet conditions, fog, moving targets.
Iron sight advantage vs. disadvantage - simply reverse the above.
The problem here is - your father-in-law doesn't respect you. I am of the opinion that if respect isn't given, it should be demanded. If it still isn't given, don't let him hunt. You’re not a boy. It is your land. I think you'll feel better about it in the long run. Of course no one wants to piss off their wife, but part of being a good and respectable man is to stand up for what you think is right. If you present it properly, you can't loose, but then again, I wish my in-laws hunted just so that I could tell them "no"! Ha...
Sure you may go a few days “not getting any”, but if you give in, I guarantee you, you’ll regret it 5 seconds after you “get some”!
This sounds like one of those dynamic, character-defining moments in your life with them. You will either gain their respect, or continue to be disrespected.
Ask him if he knows the difference between in-laws and out-laws?
Out-laws are wanted!
