I have been coaxed along to getting into serious debt to reloading recently by someone whom, themselves have just bought a single press starter kit (RCBS). He only has one caliber that he reloads for (300WM) and I will only have 2 .223 & 40S&W). I have searched this kit and also found 4 & 5 hole turret presses. Seems to me that it is a lot of work (in the beginning) to keep removing & replacing dies on a single hole press and me being a NUB I just gotta know the reason experienced reloaders (unless mass producing many calibers) prefer the single presses? TIA Peeps.
