Hello all - looking for info here. I've an interest in this old round - I've chambered a Swedish 12/7X44 barrel that had a bad chamber to this round. I found the specs in 8th edition of "Cartridges of the World" book which says case length is .875" with a standard load of 25 grains of FFg. That's what I did - now I find in 4th edition of "The Handloader's Manual of Cartridge Conversions" the case is given as .570" length. Both books give a load of 7.0 grains of Unique and make case from 50-70 brass.
Does anyone have any real info on this round? .570 sure does seem VERY short to me. Almost the same length as head diameter: .570" length vs .565" head diameter.
Thanks to all for any suggestions or info.
