I just read this thread and found out Rainer is defunct. I immediately went to Midway and bought 3K of their 148 DEWC's. I already had 4K + a partial box; but now I have 7K
Rainer's DEWC is - far and away - superior to any other plated DEWC out there - bar none. All others are rounded on the edges and don't really cut a clean hole in paper. Rainer's actually have a ridge and so they cut a very clean hole. They are superb. I'm going to miss them. Of course, at 7000, it's going to be a good while
BTW, Midway had them on clearance and I only paid $71.something-something for them (per 1000). That just over 7 cents each - about that for lead slugs.
As far as other plated bullets, I go with X-treme for everything else. I have been very pleased with their products and service.
I have used Berry's too. But I have only bought them from my LGS when there was an immediate need; and that's probably not the most economical way. I have never bought Berry's on line.
