Quickload question, RWS brass

[PigKiller]

I did a search and did not find this question brought up before, so here it goes.

I am just getting familiar with the Quickloads program & I don't THINK it has RWS brass listed.

These are the choices I see:

(F) Federal
(N) Norma?
® Remington
(W) Winchester
(@) ?????? Is this a blank where you add the data for any other brass?

As usual, thanks in advance
