There are only a couple of sites that list fire forming the 8x52R Siamese cartridge. What base cartridge is the best one to use to fire form this round for hot max loads? The 7.62x54R?, .348 Winchester?, 8x56R Hungarian? 45-70? There are post using brass rings at the base of some of the cases, a step I'd rather not do. I do how ever plan to load the Siamese case up to the max working pressure the Mauser action was made to operate. What have you guys used and how well did it work?
Thank you for any info.
