I have the RCBS kit - labelled "Primer Pocket Swager Kit - 2" - it contains stuff to do both 7.62 NATO and 5.56 NATO - I used the smaller set up a lot to prepare brass for our Grandson's .223 Rem - but is the only type I have ever used - so nothing to compare to, if it is really good or not. Some set-up involved, as I recall - it works within my re-loading press. I was doing batches of 50 cases at a time - reload them and send them off to Grandson - that slowed down quite a bit, once swaged brass started to come back, to get "re-filled".
