Hi there
there is tonnes of good valuable info here for sure but ultimately only you can decide what you need based on amount of ammo needed and skill level, there is no question that un skilled reloader can make a bunch of useless ammo in a progressive whether that be from assumption or lack of knowledge or both, I have never owned a dillon but have owned many lee presses, hornady rcbs and frankford lees are great presses to learn on because you will be farting around with the primer systems on them all the time they are good presses for the money but lack any kind of tolerence in the auto priming dept and thus the need to tinker at least with every single one i owned anyways, the hornady progressive is a nice kit but expensive and i am not sure if a dillon would be better money spent??? the franford was junk cool design poor delivery , as of today I have a redding turret press and an rcbs summit single stage and honestly i had a lee cast single stage that was perfect regardless my opinion is this, a turret press will give you all the love of a single stage and with being able to set up all your dies at once still make some quick pistol ammo. and when your ready to go streamline keep it use it for rifle and get your pistol progressive just another opinion but you will end up going down a rabbit hole where there may be a lot of slightly used presses at your garage sale hahaha if that is the case i also suggest you reload for 410 shot gun get a press and let me know when your next garage sale is cuz i am in the market for a 410 reloader hahaha just kidding ..... but seriously read read read there is so much good info out there and be safe and welcome to the crazy
