I have two rockchuckers I broke down a few months ago and bought a RCBS turret press with enough plates to set the dies up that I use the most. It has improved my handloading to the tune of anout an hour per hundred rounds I never load much more than that at a time because I get tired and tired makes mistakes.
If you are just starting out I would sugest you get a single stage, until you learn the in's and out's. I have been handloading long enough that I inspect at each stage, the sequence is the same with the turret press. After tumbeling I lube, size and decap. The case comes out I check the primer pocket, trim,recheck case length. Install new primer with a RCBS Hand priming tool. Chambfer case mouth. If useing a three die set I flair casemouth, if not I wiegh powder charge and charge the case, then set and seat bullet crimping in the same die, then remove and check OAL wipe off any residual lube and put in box. With a single stage I was doing the same thing but I would do all cases at each stage then change dies About a five minute operation. Why it saves me an hour on average I can not figure out since the die change takes hardly twenty minutes total. But Any way I have not noticed any degrading in quality of handloaded ammo since I began useing the turret. If any thing I seem to be getting a bit more consistante.
