Rcbs rock chucker here. No concentricity gauge or neck turning. Half minute loads and better are very doable. Lee collet neck sizing dies are very affordable and work well. Forster and redding also make very good dies if you want to spend a little more there.
The Rcbs kit mentioned above is a great start, and definitely worth looking at.
Good calipers and the hornady LNL kit will help. This will let you measure the bullet/cartridge from ogive to base. MUCH more consistent than tip to base oal.
Projectiles, 178 amax is priced very well and shoots great. Works for targets and hunting for me. Usually runs around 29 dollars for a 100 box. Pulled 175 smks can be had for under 20 cents per pill when you find them. They shoot well in my experience, especially if you sort them.
Brass, once fired stuff is usually easy to find and pretty cheap. Federal is okay, but usually does not last long. Winchester is great for the price. Lapua brass runs 75 to 80 cents per case, BUT it is great stuff AND I have several batches with 9 loadings on them at moderate velocities. IMHO great quality stuff that lasts. Kind of mitigates the higher price tag.
Powder, Varget works for me. It is not very sensitive to temperature. BUT you can find surplus powders and load on the cheap if you want to. Just be sure to really work up your load, as any powder (especially surplus) can vary greatly from lot to lot.
Primers, CCI standards have worked just fine here. Havent seen a big enough difference with the match ones to make me want to buy them.
If you have the budget, consider a good chronograph. REALLY helps when developing loads so you can see if you are getting a good group AND good velocity spread/SD.
You wont save money. You will very quickly shoot up the difference lol. That said, your cost per round will go down a good bit, but you will need lots more rounds : ).
