I am looking at getting back into reloading after MANY years. I had a 550 in the past because I was loading 3-4 different calibers and I liked the ease of changing calibers. I am now going to be reloading only 1 caliber and was wondering if the additional cost of the 550 was worth it since I will only be loading 9mm. For those that have or had both, what are your opinions? Wanna kill these ads? We can help!
