I load rifle rounds via a single stage method using a Hornady progressive turret press. I only put in one die at a time for neck sizing, or bumping shoulders, of full length case sizing, and bullet seating. Ideally a single stage press would work slightly better, but the method is the same.
One operation at a time. I'm not an expert, but for rifle rounds the accuracy comes from consistency in all things including powder charge. My experience is that you need to throw a charge and trickle up to your desired load weight. No powder measure that I know of throws a perfect charge all the time, sometimes a little more, most times a little less, but never really bang on in my experience.
For high volume reloading (9mm pistol), I use a Dillon Square Deal B. It takes proprietary Dillon dies. A Dillon 550 or 650 uses industry standard dies that would fit in RCBS, Forster, Lyman, Lee, etc. presses. Of the three progressive presses I have used, Dillon, Lee, and Hornady. Dillon is by far the best, least troublesome in my opinion.
As has been noted you will need ALL the other stuff to go with your press. Dies, scale, a tray to hold the cases, a funnel to fit over the neck of your case, powder trickler, powder measure (if one does not come in the kit), funnel etc. A very good scale is also important if you're looking for every bit of accuracy, a really good scale can run your several hundreds $$ like the AND Fx120i, and over $1300 for a Sartorius brand scale that is accurate to 3 decimal points.
So, as in all things shooting... What do you want to do? What do you want to spend? There is a solution for every budget, results may vary...
