Quote: What did you use for "soldering" the extensions, lead based solder or a silver based solder? I've successfully repaired neck cracks in some of my old Berdan primed Kynoch 404 Jeffery cases that have cracked on the first firing of factory ammo and also a few RWS cases that have cracked after many firings when I've been a bit lazy keeping up with a regular annealing progamme. For the repairs I use a 'dirty' steel rod (natural black finish) that's a slip fit in the case necks to prevent run through of the solder and use a low temp silver solder, trade name "silfos". This works really well matching the colour of the brass cases so an invisible repair in most cases while sizing and annealing perfectly with the parent brass of the case. |
