Hornady's set will work with most all calibers while RCBS is one caliber specific with a few exceptions measuring headspace like 30-06 and 25-06 having the same shoulder dimensions. I like the micrometer dial read-out on the Precision Mic but the Hornady set with a good set of calipers is also repeatably accurate. I have the Hornady set plus a couple of Precision Mics. I use the Mic with 30-06 and 25-06 and another for .223 Rem and the Hornady set for all others. The RCBS Precision Mic tool for measuring bullet to lands doesn't work very well but with a lot of tinkering you can get accurate results. If loading for only one or two rifle calibers I'd rather have the Mic but it'd be expensive to buy Mics for several calibers. Either are good reloading tools which will help increase case life and cuts down on the chances of a case head separation.
