30-06 has been around for 100 years but is no longer a military caliber. Still a lot of 30-06 huntin’ rifles out there though. At Academy Sports, many of the larger hunting calibers seem to be in stock.
You should be able to pick up a new Howa or Weatherby 30-06 for $400 - $600. Remington 783 is also an option. (And a used one a lot cheaper.)
There was a comparison chart of different rounds and the cost -vs- the number of pounds of meat you could bag with them, and they said the 7.28 (once again???) was at the top for cost-effecttiveness and they had a small blurb about it being a 30-30 (in parenthesis, only once)
I could be totally wrong, but right next to the 30-06 ammo in the store there was something called 7.28 (???)
i am just learning about all this.
The only thing I ever owned before was a 12 gage with some deer slugs and pheasant loads, but I recently bought a Rossi Circuit Judge because I just though it was way too cool to have a shotgun made like a revolver that would shoot both .410 shotgun and 45 cal ammo.
And the 410 shot for indoor home defense would not take out a structural wall like a 12-guage might
