RE: Merkel Drillings
The 9.3x74R usesthe samecommon .366" bullet like the other 9.3's use.... It's available from several bullet makers today.
The 74R brass is made by several companys,but i've always liked the RWS brand best... This is not a high pressure round, so the brass last a long long time, at least RWS brand does...
Factory loaded ammo is also available from RWS and a few others...
I hope this helps some,
