Lots of good advice on here really...
It's hard to say if you'd benefit from loading. Have you been saving all that brass?
You can get an RCBS kit for a decent price. Couple hundred on sale I think. Add a couple more to that for other stuff you'll need. There's a few items missing you'll need but guys around here can square you away with a list and you can probably find used stuff to buy on here. Then if you're doing this to work up precision loads safely, which I suppose you wanna do, you'll want some kind of chronograph, ideally. Ask around. Lots of us have some loading gear laying around, extra stuff that got replaced or upgraded.
For what you shoot, you won't save money, but if you plan on shooting more (if cost was a limitation but you can afford the initial investment, then you'll be able to load more than you could buy) or loading for different rounds, it could be beneficial. I agree you shouldn't do it solely to save money but rather as a new hobby plus a way to tailor rounds and get better ammo. Loading should be fun for you and you should be able to set aside time to do it right, shouldn't be rushed. Should be a relaxing, repetitive zen type endeavour really.
I'm sure you have and shoot more than just that 7mm, am I right? Consider if loading those will make it worth it.
But if you really are only firing a few hundred rounds per year, then yeah, just buy 'em I guess, find the best and stick with 'em and just build up data in your dope book. Loading will only complicate things and add more shit for you to have to do as well as open a rabbit hole of new gear you just gotta have.
Some guys on here have several thousand invested in loading and they load on a single stage press. They ain't cranking out volume like I do on a 650, but their ammo is technically perfect. You see, they're vested in loading, not just shooting. Shooting for them is only part of the game. Same for me but in a different way, the only ammo I purchase is +p+ or .40 carry loads (too dangerous to load on your own, these rounds kaboom more pistols than any other I believe). Other than that I load, from 9mm to belt fed .50. Now I've recouped cost, many times over in some cases, but it's only due to massive volume and years doing it, plus the fact I load for a belt feeding .50 and get components, mainly brass, from military auctions.
Oh, finally, if I didn't HAVE to load/reload, I certainly wouldn't be doing it. If I could afford high end ammo for some things and cases of this and that for others, I would. But if I wanna be able to shoot much and keep plenty on hand, then I'm gonna have to load it myself.
Good luck either way you go!
