Keep in mind that $60K is what you'll have before you are taxed. Your yearly net will be much lower once the state & fed get done with you. All your hobby money comes from what's left over.

If you are range shooting a lot, consider reloading ammo vs. premade. The gear is not expensive and it will drop the price 1/2-3/4.

Do you live near skiing or do you have to travel to it? You'll lose your lift ticket discount when you graduate so your costs will go up there. Skiing at least is seasonal and you could budget for your trips. Perhaps reduce the frequency you go but stay longer when you do to shrink travel costs.

Basic cars by themselves are a huge monthly draw. If you are making payments on a performance car, even worse. If you are modifying what you have with aftermarket parts you could scale that back.

What you really need to consider is a hard budget. After you've met your expenses, put aside funds for emergencies, etc. see what's left over. That's your entertainment fund. Whatever is in that is what you have for the month to spend on your hobbies or hobby. Of the 3, shooting likely ends up being the least expensive.
