When I was a kid, I rarely considered the total cost of purchasing something. For example, people buying a cheap, used snowmobile rarely consider the cost of maintenance, storage, a trailer, a truck to pull it up north and the cost of ten nights in a motel up in the snow-zone.
That $1200 snowmachine quickly morphs into $10k. It is different, in my mind, if it is a tool you will use once a week. Then you don't need the trailer, truck and lodging. That would be the difference between a snowmachine in southern Michigan and utility quad or tractor you can use to haul wood, spin seeds, drag deer, carry fencing tools.... through moch of the year.
The cost of a firearm includes buying secure storage like a safe. That presumes you don't already have a safe with room in it and that you might have visitors who are not trustworthy around firearms.
Let's look at the .350 Legend.
Suppose you have room for one more firearm in your safe space. Also assume you have a friend-of-a-friend who will let you borrow an AR lower.
.350 Uppers can be found for about $250. Add twenty bucks for shipping and you are looking at $270.
Budget another $200 for a scope and $50 for the rings. Rolling that into the $270 gives you $520.
A set of flip-up iron sights, aperture rear and post front, are going to run another hundred. $620
Reloading consumables, bullets-and-cases, and a set of dies will run at least another hundred. $720.
Three hours of range time will run about $50. $770.
Can you do it cheaper? Heck yes. A scoped "package" gun from a major retailer might run $350 on sale. Buy a box of factory ammo. Don't sight it in and you can be hunting with a .350 Legend for half that price.
Or, I could buy the upper and install high quality iron sights on it for about $350. Iron sights are perfect for the finish-wounded-deer mission and very adequate out to 100 yards in any reasonable light. They give up something to the scope when shooting in heavy cover. With a scope, you are more likely to pick a window in the brush and hit the deer in the vitals.
So it comes down to a choice between buying that new freezer Mrs ERJ has been talking about or buying something to fill that freezer more elegantly than the Mausbert 5000 that has been filling it for the last twenty years.
The other dimension is the forlorn hope that Michigan will see the light and allow downstate hunters to use everything up to .30 caliber centerfires as long as they are in elevated stands. The point about the elevated stands is that the hunter is often shooting DOWN at the deer and have a dirt back-stop.
And I have a friend-of-a-friend who would loan me a nice .308 or ought-six.
