Brass Stretching

[ken1989]

Does anybody in Canada do brass stretching? I need some 30-40 brass made into 40-70SS. I have some 30-40 brass that was streched to 40-70SS but it is getting close to end of life. Thanks!

Kal Tool and Die in Winnipeg makes case stretchers, not sure if they’ll work for what you need but it’d be worth exploring. Can’t you just fire-form .30-40?

Isn't 9.3x74r a longer version of the same basic case? I know they aren't cheap but might be easier and last better.
There was recently some on the EE.
