You'd have to process your brass fully, trimming a bit shorter than 1.75, then setup the X-die for later reloads.
I considered this for myself, but I normally shoot with a group of friends, and I get all the brass as none of them reload. To keep my processed brass seperate from their's is not practical. We don't shoot from benches and we don't stand still while we are shooting.
So I just do the 2 pass thing, one trip through the 650 with decapper, trim die and the GS Custom swager. Then tumble off lube, and reload on my 550. This way has the added advantage of allowing me to load while one of my mates is processing brass, and another is putting loaded ammo on stripper clips
.
I almost never load on the 650 anymore, it's only used for 5.55, 7.62 NATO, and 300 BLK. processing now.
