No sfdj, you don't understand, depending on the cartridge some is Lapua, some is Norma and some is Rem etc, etc. 300 RUM and 300 Wby are both definitely Rem. I have purchased and done comparisons with these two and then sold them because I can buy R-P for 1/2 the price and I'm quite happy to do my own prepping. Lapua do not make RUM cases nor do they make belted mag cases, is what I have been told.
OP......just checked my stash and I only have 50 new cases and 150 fired cases. I thought I had another 50 new and would have sold them to you but such is not the case, sorry. There was an ad on the EE a while back with 100 Norma........but he wanted about 3 bucks a case IIRC. Put a want to buy ad on the EE there is gobs of it out there, you'll find some.
