First off I do not know if I am too late to help you here. It is very difficult to give someone an answer to a general question - What do I need? My gosh, you need lots of things. You did not mention where you are at in hand loading. You said you have got started, but you are not very far along if you do not know what bullets, primers and powder you want. My preference is not what yours may be. I prefer Remington 7 1/2 primers for small rifle, because I have always had good luck with them. I do not have much experience with large rifle primers, but my opinion is that it really does not make a whole lot of difference which one you get. Get the shiniest, cheapest, prettiest ones you can get. I have used Winchester primers for that duty. Powder wise maybe WW748 or H335 for the 7-Waters and 223. IMR 4350 for the 7-08 and RL-22 for medium bullets in the 7 Mag and RL-25 for your same rifle with heavier bullets. If you do not know what you want. it is all a crap shoot. You may spend $200 on supplies and find out you do not get satisfactory results with any of them. How much money will you save then? There is no short cut. I am not flaming you at all. Reloading to me is a very good hobby that I take seriously. I started out to save money, but I really have not saved money in the long run. I keep buying more and more equipment/gadgets and the price of reloading items keep going up, same as factory loaded ammo. Then I shoot a lot more, developing loads for each rifle/handgun. If I shot factory loads, I would buy 4 of 5 different kinds and find the best one, and let it go at that, only shooting them at live game a few times a year each. I get satisfaction from the development of the load. Once I find the magic combination, the interest in that particular gun wanes and I am off doing another one. Part of the fun of it is load development. If you really look around this site, you will find that the folks who frequent this site are very helpful, but they are most helpful when a specific question is asked, like I have been having trouble with groups at 100 yards, this is what I have done so far and nothing seems to help. Then you have some where to start to give advise to. When someone asks a general question What powder do I buy, there are so many different answers no one with any knowledge wants to point someone in the wrong direction, so you do not get many answers. You always get a few that say they like such and such powder, but that does not mean it will work for you. You have do some of the work yourself. Do not blame the the people for not answering a question where there is no answer. I try to keep a large variety on hand to try out. I buy 2 or 3, 1 pound canisters of likely powders at a time until I know which one I want. I keep a large variety of bullets on hand, but I buy 100 at a time until I find exactly what I want, then buy in 500 lots. I presently have 15 different kinds of .224 bullets on hand. I hope I made some sense of this to you. It is only a bargain if you get what you need, if it is something that does not work out for you, then that is money down the drain, you did not save a thing. Develop your loads, find out what you want, then next year when he goes, buy a large quantity of what you want. Just my 2 cents. Good Luck and Good Shooting.
