I get the feeling this is going to hurt, but.......here goes.......I have a 550 set up for .45ACP. I also have a pile of misc parts but not enough to totally retool over to 9mm. Assuming I needed to buy all the parts required to load 9mm, the cost was approx. $270 when I stopped at Dillons today. The cost of a brand new Square Deal is $379 (+/-). Since the 9mm is for my wife, and she is willing to do the reloading for herself, should I spend the extra $100 and get her her own press, or allow her to share mine?
