I won't debate the Lee CC vs. RC. Each is an excellent press and I like them both. Both are extremely strong.
My RC is outfitted with the Piggyback II for progressive production of pistol and 223 rifle rounds using pre-primed cases. The Lee is primarily for larger caliber case sizing, depriming, and mil brass primer pocket swaging. An RCBS Automatic Bench Priming Tool (not shown) does all priming duty off press. A manual indexed RBCS 4x4 progressive reloads large caliber rifle rounds.
IMO the most difficult and time consuming part of reloading is case preparation, without which progressive reloading becomes a myriad of stops and starts, which become frustrating.
I will show my neighbor the hows and whys of several different varieties of presses, priming systems, and ammunition manufacturing machines; dozens of reloading manuals; logs of my reloading experience; manual and machine case prep; case trimming; case cleaning; and a multitude of other machines. From this limited, but unordinary subset, it is hoped he gets a firm foundation and feeling for the manual production of accurate ammunition.
I know that what I have to show him is much more than a single session's worth of information. It would be wrong to attempt to introduce 30-years worth of accumulation in the first hour.
Initially I will keep it simple. I will show him the basics of the Lee Loader for 9mm ammo. It won't be his 30-06 rifle round. It won't even be a pistol caliber I shoot. I just happen to have one - and only that one. The Lee methodology will be expressed as the prologue to the single stage press in manufacturing accurate ammunition one-round-at-a-time.
Then we'll discuss the necessity to keep records, case prep, play with a few machines, and I will let him borrow my 1970 Lyman's 45th Ed. reloading handbook to read at home for its simple, direct, and uncomplicated explanation of most things regarding this reloading hobby - including cast. That should wet his appetite and we'll move slowly toward 2019 thereafter.
