The Swedish Mauser chargers hold the '06 cartridges and work well in my '03 Springfields and 50 FN Mauser.
Original Springfield ones were frail and rusty and had their tabs broken off. They're no longer common, at least on this side of the Northern frontier.
IIRC, there used to be some commercial ones made for the NMC target shooters made from stainless steel, but it's been a couple of decades since I've seen them advertised.
PM me if you can't find some Swedes.
