Luckily for me, my wife and I have been together for 30'ish years and been married for 25+ so she knew what she was getting into well in advance. That said, I only recently began to cast, and so I sat down with her and explained, "see here honey, these are what I shoot in several of my revolvers", as I pointed out what the Cast Performance bullets went for per 100. Then I said, " I can spend the same amount for 5 hundred bullets on this mold and these lead deals here, and I can pour up close to 1K or more for the same amount or less once I recoop the price of the mold".
She knows I am somewhat thrifty even if I DO like to shoot the better stuff. She also knows I use just about all of it to put meat in the freezer at one time or another. Luckily for me she also knows, it's only a few blocks over to the beer joint, where I could easily go play pool and down cold ones every evening as well. I'm not telling her that I really just ain't up to the beer joint thing anymore, but she has raised an eye brow up on the last time or two I asked to get a transfer into my paypal account to pick up a new mold.
Hang in there GP hopefully she will let up on ya some. Yea you might also want to invest in a locking cabinet as well.
