There are SO many kinds of powders, I'm overwhelmed. From reading the past relevant posts I could find, it looks like Winchester's WDF powder is recommended for new reloaders like me. I'm interested in reloading for my 9mm G26/G19 for range practice on a Dillon Square Deal B. So should I start with the WDF? Other question I didn't find answered... is there a formula or easy way to know how much powder to buy based on the number of rounds I'll be reloading? For example, how much powder would be needed for 1000 rounds? I haven't started powder shopping, so maybe this is answered on the websites that sell the powder? I would guess that it varies depending on type/brand of powder, but that's just a guess. Last question (for this hour) ... Is there a listing of commonly used Glock Talk acronyms and abbrieviations? In reading through some of the posts, I feel like I'm reading another language .
