Does anyone have some good starting loads using 168 and180 Bergers with IMR7828 or H1000? If I get hooked on the bergers how big a job is a Wyatt box? Also in my panic to stock up on primers I bought a bunch of magnum primers. Will these be ok for the STW and will I have to change powder charges when using them? Are there any considerations for use in hot weather? Should I use them? I have always been a basic reloader but since meeting you guys and catching your illness I realize that I have to step up my precision , quality and knowledge on the reloading bench.
