Welcome to LRH, glad your here. There's so much to learn about reloading and doing it right. You have so much information available to you just starting out. When some of us started there was no internet (oh boy, I'm getting old). At first, some people start just to make cheaper and hopefully better than factory ammo. If these attributes are all you're after then it usually doesn't take long or much effort.
Consistency and attention to detail are the keys in reloading for Long Range accuracy. The majority of equipment out is good. I've been reloading since the mid 80's and still have the same RCBS RS5 press. It's starting to wobble a little but still makes very good ammo. I have a RockChucker that my Dad left me and I should probably incorporate it in to the fold. These are the only two single stages I have ever owned/used.
I did have a Hornady L-N-L Auto Progressive for quiet a while. It is a nice machine. Once it's set up a person can crank out 500 rds of pistol ammo an hour with a little practice. I did load some rifle, hunting ammo with it for a couple of guys and they really raved on the accuracy of it but I never loaded any for myself. Mostly just auto pistol (.380/9mm/40SW&45ACP) but it does rock. I stopped using it and sold it to someone (don't remember now) on this forum a few years back.
As for dies, I have all brands except Wilson, I think. A lot of my dies started out just for building hunting ammo and through the years I have drifted farther in to the precision aspect of it and have replaced them with better, higher end dies. Not to say that you can't start out using the best for hunting, it's just I started years ago with what seemed like nothing but bills, a small family and a desire to work and hunt so I got what I could at the time.
It's hard to list all the accessories that you "need" because reloading is something that you really learn along the way. You absorb all the info you can, develop "your" style of reloading and then get tools and gadgets you need to help you create the loads that your rifle(s) need to shoot their best.
You start out being the man that makes the ammo and squeezes the trigger but turn in to a rifleman that shoots those incredible groups close to a mile away or drops that beautiful 10 point standing in the fields edge at dusk at nearly 3/4 of a mile with one shot. You don't do it for praise or glory, you do it because you're that good and you know what your rifle and ammo, that you built will do.
Good luck in your efforts. I hope you get the enjoyment from reloading and shooting the way a lot of us on here do. I've been at it for almost 35 yrs and there's hardly a day that goes by that I'm not thinking about some part of it. There's always something to improve and it is addictive.
