The RCBS press is a well built press. I have used my friends on a few occasions. I would suggest starting off with somthing less expensive though if you are on a budget. you might consider the lee breech lock press due to the cost. It will load all the calibers you have listed. I have one and I like it. One thing that I have learned about reloading is, that it is addictive and you may find yourself buying different guns so you will have somthing else to reload for. I currently reload all my rifle ammo on a single stage, but since I started reloading, I find myself shooting more and I out grew the single stage for pistol ammo. I then moved up to the lee classic turret and I was just able to keep up. now I moved on to the hornady lnl-ap for pistol ammo. Since it uses the same bushings as the lnl single stage I also got one and retired the lee presses. I can load develop on single stage and go progressive on the ap with out adjusting dies. You should consider what you future needs will be. If you can save a little on equipment you can spend more on componets.
After you get a press and reloading manual, you will need dies. I have mostly lee dies and they get the job done. I dont shoot benchrest and they produce accurate rounds. I also have rcbs and hornady dies. On pistol dies you should look at carbide dies. the Lee four die set with factory crimp die seems to be the best value.
You will need a set of calipers for measuring
Next you will need some type of case trimmer at least for rifle. The lee system work good for less investment. I started with these but you cannot tinker with case length. the lyman universal trimmer seems promising and is currently on sale at cabelas.
Next you will have to prime the cases. most presses have the ability to prime, but some the most effective way to prime on them is to place one primer by hand onto the primer arm at a time. You might look into a hand primmer. I have both the lee and hornady hand primming tools. the hornady uses the same shell holders as the press while the lee shellholders are different. The lee Challanger and lee classic turret presses uses the lee safety prime system which works good if properly adjusted, but is made of plastic.
Next you will need a way to charge the cases with powder. This can be as simple as only using a balance beam scale to an automated powder thrower. It will take longer to charge with just a scale and the automated route is expensive. You may look at a powder thrower. i like the hornady lnl powder thrower and it works for pistol and rifle with the correct drum. The lee perfect powder measure works,but it is almost all plastic and does not run as smooth. On my turret press i had the lee pro auto disk measure and it worked very wellm, but I was limited on what it will charge.
Not to be nosey but do you live near your grandfather? He probley has a wealth of knowledge on what works. you may give his press a try to see if you like it. My best advice is to keep an open mind about what you want and need and research what each product has to offer. But be aware some people have brand specific loyalty and may try to sell you on their brand. Also dont be afraid to let your wallet voice it's opinion. The lee equipment will be the least investment. My hornady equipment has better quality like rcbs, but costs more. If you get somthing you dont like you can always list it on ebay and hope for the best.
