Quick question all from a newbie to reloading, I have equal amounts of lapua and Win. brass. I will be doing load develpoment this week using the Lapua brass. Is there a rule of thumb I could use for making the same load in Win. brass, or do I have to do a full load devlp. with that brass also??? Over time I intend on phasing out the Win. and replacing it with Laupa.
