Ozzi - sounds like you have not reloaded previously, and perhaps have no mentor to get you started?? Buy some reloading manuals first - 2 or 3 or 4 - almost all have first 1/4 or 1/3 with step-by-step instructions how to reload - different manuals seem aligned with different reloading tool makers. Does not really need to be latest edition - so Lyman 49th, Speer #13 or #14 and so on. But you are buying them for the reloading step-by-step information - as much as the reloading data for specific cartridges and bullets.
Then you probably need a dependable calliper that you know how to use - you are going to measure a lot of stuff - so accuracy to 0.001" about usual - not much gained for a person starting out to imagine that he is measuring to 0.0001" - is a VERY hard thing to do repeatedly.
Like many on here, I started with a Lee Loader - so a hand tool - neck sizes only - can only reload new brass or brass previously fired in your rifle - has a chart that tells you what powder to use with the included scoop - for whichever weight of bullet that you use. I have not bought one for probably 30 or more years - if they are still made, I suspect less than $50 - and you will make rounds that "go bang". I believe several of my earlier deer were taken with rounds that I made with a Lee Loader tool.
Pay attention to details and be a bit critical in your thinking. 4895, H4895 and IMR4895 are three different powders - so some will claim them to be interchangeable with each other - you will need to discover how they arrived at that - the manufacturer's are either defunct, or do not say that.
After that, is a plethora of items that could be bought - you will likely want some tool to weigh or meter powder - balance beam scales pretty popular for that - but then likely want a trickler to go with it. Getting a press - now need shell holders for the cartridges that you want to reload, and die sets. You likely want some way to trim cases to length - is the inexpensive Lee system, or much more expensive hand cranked lathe type machines - almost all need pilots and separate shell holders which often to not interchange from trimmer to press or vice versa - some do, some do not. Likely want some way to chamfer those freshly trimmed case mouths. Some guys fussy to clean primer pockets - is several tools made for that. Same with seating fresh primers - some do it on their reloading press - other use several hundred dollar dedicated tools. Some people want to stainless pin tumble and then anneal every reload - likely many hundreds dollars for those tools. In old days RCBS shell holders were $3 or $4 - now seeing selling prices on-line and in stores like $25 or more - so pays to pay attention to what a new tool needs, to be able to use it.
Basic advice is to get several hundred loads under your belt - so, primers, powder and bullets expended - making them "go bang" - even using just reloading manual start loads - will get you going. You can get more fussy as your skills improve - is my view that unless you can show result in smaller group on target, either you were not doing something correctly, or your skill is not to that level yet. Is no end of really esoteric reloading stuff that you will read about - do not loose track is typically done with exquisitely precise custom chambers in high end barrels - often with custom made dies - by shooters who fire hundreds if not thousands of rounds per week. No doubt they can show difference on their target - the question for each of us is whether we can or not, with our gear and our skill level.
