Yep. I would have used Peterson brass, except there wasn't any (or Lapua) in stock anywhere I could find on the Internet. Graf & Sons is supposedly the sole seller of Peterson, and of course some did show up on Graf's website AFTER I submitted the article. Now have a 50-round box of it too.
Creedmoor Sports now carry Peterson Brass
just in case (pun intended) the need arises, we now have an additional source to check for availability
