Hi guys, newb here with a question on primers...

I recently bought some H335 powder to work up some loads using a 50gr vmax.

A friend suggested I use a magnum primer with H335. Because it is a ball powder. As far as I can tell, in my Lee manual it doesn't call for magnum primers.

What do you guys think? Any suggestions for a 50 grain vmax? I have already tested some Imr4895 and those loads did well, just trying something different.
