[quote=“Vlim”]I would be interested in seeing some evidence that the Erma sub calibre set needed special .22lr ammunition that differed from the .22lr issued for training rifles / training kits for rifles.
None of the manuals I’ve seen mentioned specific .22lr for pistols or rifles. Just .22lr.
As far as I know, they had a ‘one size fits all’ approach for their (standard velocity) .22lr ammunition. The manual for the pistol set does mention to grease up the individual rounds before loading them, to avoid feeding and extraction problems.[/quote]
Vlim, perhaps you are partially correct. Without looking at my manuals, I assumed the semi-auto nature of the S.E.L. f. P08 would require the special ammunition. But examining the texts I see that there is no mention of special .22 lfB ammo to be used. But reading the text further, it is evident that sure performance of the units were sacrificed by whatever organization was using the S.E.L. f. P08 in favor of having to maintain only one type of .22 lfB ammo for use in both rifles and pistols. In the section dealing with cleaning, storage and so forth in police manuals, it was acknowledged that the low powered KK-rifle ammunition would produce difficulties with the operation of the toggle mechanism.
I found some evidence for my belief Vlim. On page 359 of Gerhard Bock’s Moderne Faust-feuerwaffen und Ihr Gebrauch of 1941, Bock discusses the Erma Einstecklauf for the P08. In one of his closing sentences, Bock writes “Das Magazin faßt 5 oder 7 Patronen 5,6 mm lang für Büchsen. Natürlich sind nur die Patronen für Selbstladepistolen zu verwenden.” I think this pretty well spells out from one of the most celebrated handgun specialists in the III Reich the need for the special cartridges for self loading pistols as I mentioned in the above post.
