Small rifle primers in a 6,5x54 ? Don't you mean standard rifle primers? I've used Norma (who no longer make it), and RWS brass and both use standard rifle primers. This case is one of those that is not easily made from others.

If you're US based, I think Old Western Scrounger advertises (in Wolfe publishing's Handloader magazine), that he has 6,5x54 M.Sch. brass. Just beware that, the RWS brass is fine, but the RWS bullets are undersize and their groups are therefore oversize! Much better are Hornady 159 grain round nose. These are standard .264" and will fit any 6,5x54 M. Sch.

Hornady's larger 6,5mm Carcano sized reloading bullets only fit pre-war 6,5x54 M. Sch. and you'll need a cast of the rifling to be quite sure they're safe. But they are the best if your bore is one of the earlier, pre-war oversize ones. (assume nothing until you have the rifling cast dimentions). These bullets,(the Carcano ones, that is), need to be carefully loaded to a much shorter Over-All-Length than SAAMI or C.I.L recommend on account of these bullets not being tapered. Fail to do this and you'll have all sorts of problems. You'll need a Hornady OAL guage, (that used to be made by Stoney Point), to check this. If you have .264" bullets, including the .264" Hornady ones which are tapered, the SAAMI / CIL length should be OK.

As for VV powders, it'll be a sad day if we can't buy these anymore.
