I have three presses now. My first was a dinky little RCBS Junior or something like that. That served me for years and years.

Then when I acquired the .450 No. 2 I ended up purchasing a large turrent press but also asked about an RCBS single stage "Ammomaster" I think it was (???) It was designed for the .50 BMG. Something got mixed up and the gunshop thought I ordered it so I I took it anyway. It does make loading really long shells easier than unscrewing the seating die each round.
