The Federal primers are hotter than Win, Rem, CCI, Fiocchi, Nobel, Rio. Since we are loading on the lower end of SAAMI specs there are viable substitutions. Off the record info from manufacturers is yes, you can substitute the lower burn temp primers. On the record info is dictated by lawyers. It is what it is.
Mike are saying that Cheddite are also hotter?
