Welcome to the club.
For 300blk I have a hornady LNL press, Forster bench rest full length sizing and also seating dies, and a factory crimp die. I started off with the lee set, but was very disappointed with them and put them aside when my forster stuff showed up.
For case prep I have the Rcbs bench mounted super swage (just like the dillon), a primer pocket uniforming cutter, and flash hole uniformer (only really used when it's needed) a hornady trim station with the regular hornady blade to do rough/large cuts down to the neck, and then an Rcbs 3way to do my final trim. It's chucked to my dewalt drill, so its super quick and efficient. I did make a jig to hold 556 brass, securely in place so I could cut the neck off with the dremel, but got sick of that and just use the hornady cutter now.
Midway is selling blemished seconds .30 bullets (it's really nice stuff) right now for super cheap. I picked up 5000 155gr accupoint spitzer for an insane price, so I will be shooting quite a bit this summer!
