I was reading all the reviews on both of these powder machines and they both had equal review stars. A couple of people mentioned that the Hornady will shut off if this garage is over 80 degrees. No one mentioned anything like that with the Rcbs so this is why I ordered this one. Did I make the right choice? My garage gets hot in the summer and while I try and reload during the cooler parts of the day, it will hit 80 pretty quickly. Has anyone used either once of these?
