I think anywhere it’s damn-near the perfect all around rifle. Lever actions is faster than a bolt and less chance of failure due to it being a lever action.
If he wants just a nice long range, sniper, or hunting rifle I would go with a .308 or .30-06 bolt. I am merely just going from his desire for protection, hunting, reliability, toughness etc. Most likely just to eat his .22 will take care of eating but if he has to take on a boar, dogs etc. or zombies.
Ammo is not at a premium since it’s a 30-30 lever and not a gas powered gun but there is crap tons of it around.
I have one and tho I have ar’s, m4, ak, h&k 94, rem700, savage, and the list goes on ultimately the win94 30-30 is by far my favorite.
A lever action in a good pistol round like the .357 makes an excellent all around rifle. It will kill four and two legged creatures, put food on the table if needed and protect the table if needed. You can carry aq back-up revolver in the same ammo so it doesn’t require a second ammo to stock. .357 rounds come in a variety of load and bullet. The jacketed hollowpoint is the best all round though.
