I do the same thing... works for me as well. It makes those ugly 6 hexagon or octogon crimps quite round and then makes the nose of the hull noticeably pointy.
I use the MEC 600 JR. I believe the more expensive MEC presses have an additional die that tapers the end right on the press but the RCBS die does an awesome job all by itself.
Also, I pour some motor mica into my bag of wads. It coats the wads (like it is supposed to) and since the stuff tends to get everywhere when you handle the wads it winds up on the outside of the hulls as well, making them slide in and out of the gun easier.
