I sent Reeds an email, will see if I get a response. Interesting notes about the RWS brass. Most of the posts I have read have been positive, go figure. All the more reason to try the S&B brass. Just have to order dies. Looks like the mauser and rimmed dies are the same. RCBS lists them as being the same but other die companies do not seem to list them that way??? I am excited about this little cartridge. Of course it does help that I have it on a Gibbs Farquharson action.
