Corey,
I had those type of discussion with my wife, 25 years ago (Oct 23 will be 25th anniv), here is my logic,Iam just following the commands of scripture:

http://bibleresources.bible.com/keywordsearchresults.php?multiplemethod=all&nu mpageresults=25&select=searchBible&keyword =kill+and+eat&version=51&Submit.x=11&S ubmit.y=16

Acts 11:7 (Whole Chapter)
And I heard a voice say, ‘Get up, Peter; kill and eat them.’

so you need the bullets to kill and eat to support your family, and if you don't support your family this is what God says:
[ol][*]1 Timothy 5:8 (Whole Chapter)
But those who won’t care for their relatives, especially those in their own household, have denied the true faith. Such people are worse than unbelievers. [/ol]
The meat we support our families with is the healthies meat on planet earth, it has no chemicals or preservatives and is 1/2 the chlestrol of beef, so you are doing the right thing financially and health wise for your family.

Now it is biblical for a wife to run the finances, Proverbs 31 gives a whole chapter lots of example such as this:

Proverbs 31:16 (Whole Chapter)
She goes to inspect a field and buys it;with her earnings she plants a vineyard.

Areasonable allocation per week for gas and guy things wouldhelp, which is what I did.
That is my logic, hope if helps. Best Wishes.
