I have some 243 brass brand new I purchased to fireform to an old 6.5 SLR that I have since rechambered.....however, I cannot remember the brand name. Im away from my stash for the next couple days. If it is Lapua, I'm sure we can work something out.
Check with the gunstop in minnetonka, mn. I think they had some last time I was there. They do ship. If the website doesn't show it, call them to make sure.
