Seems like this has been beat to death, some see value some don't... No different the nything else I guess. Fwiw I have 6 45s, I reload the same ammo for all of them and for a few friends who have 45s. 5 of the 6 have barrels from high end barrel makers, nowlin, kart, Wilson... I load probably one of the most difficult bullets to feed for a 45, 250 gr lead flat nose. I don't use a fcd and I have no problems in any of these guns. My brass is all range brass. I use a dillon 550 and dillon dies.
If you feel it provides reliability then use it, it's an expensive die. But I have not found the need. I wouldn't go out and get it till there was a problem to solve and you exhausted other options.
