OP, just buy one of the "complete" kits, which have everything you need already in the box.
I would suggest a :steek" RCBS, Dillon and depending on your likes or dislikes, stay away from the lighter LEE or other Aluminum framed press.
The press in Okay Shooter's picture may be an exception.
I'm not saying the aluminum presses won't assemble accurate ammunition, they will, the steel presses are just smoother and feel better to most people.
Most folks I know who start out with a light, low end aluminum press end up switching to a steel press later.
I would also look for a kit with a "digital" scale. They're accurate and fast to read.
Beam scales are fine but slower, not much if any cheaper, and it's easy to make a mistake by not having them properly leveled and zeroed.
Most good, local gun shops carry the kits as does Cabela's, Canadian Tire and a few others.
Look at what the banner advertiser/supporters have to offer.
Unless it's aluminum with a light frame, it's just about impossible to wear out a press, or set of dies.
Most kits will have a relatively recent reloading manual full of recipes. Often they are bullet manufacturer specific or even oney manufacturer of powder type specific.
If you're just starting, you will need a newly published manual. A good choice would be the Lyman #51, which has a good selection of appropriate loads for a range of different powder manufacturers. This is important, because the powders on the shelf today, which are mostly very good may not be listed in older manuals and many of the powders in older manuals are no longer available, no matter how good they were.
If you don't comprehend written instructions well, most kits come with videos to help.
There are also several Youtube videos.
If possible, get a mentor.
As for those ''magnum'' primers, many hand loaders use magnum primers for all of our loads and load accordingly.
Using starting loads in a new to you rifle is always prudent.
Just because a load is a tack driver in someone else's rifle, doesn't mean it will be in your rifle.
Many here, including myself have had rifles showing "pressure" issues beginning with starting loads.
Slightly flattened primers are normal for most loads, when they start having "ridged craters" where the firing pin strikes, your loads are getting hot. Maybe not Kaboom hot but approaching the upper limits of your equipment.
