I wasn't as worried about the punc... didn't really know... what I assume are military rifles ( I guess I recognise "duce" but none of the others )
wasn't sure if the OP wanted to shoot 10mm or actually 10 mag ??? it used to be pretty obscure
I was likely one of the 1st to ever load the mag cartridge, though the Accurate manual was just out & had load recipes in it ( I bought one of the 1st Automag 4's in 10 mm magnum... ( original loadings pretty much recommended Accurate #9 ) I've since loaded several other powders, since I also have a Contender barrel & a S&W 610 that's been chambered for 10 mm magnum, so I shoot that cartridge in 3 different platforms...
