its from 357 max case
It is a 357 max case with a new neck formed. If I recall correctly you just run it through the 7 tcu sizing die or something. Velocities should be about the same as the 7 tcu. For more info I would check with someone like accurate arms. They have always been helpful with information seeking. :grin:

The 7SM is a 357 Maximum case necked down to 7mm and according to Sierra you can substitute 7TCU data for the 7SM......just think of the 7SM as a short necked 7TCU.
I've got a 14" factory TC Contender barrel in 7SM and really like it.....it 's a real tack driver.
I'm loading; Winch. 357 Max cases....WSR primers....Sierra #1900 120gr bullets....30.5grs of BLC-2....OAL 2.483.

Can you tell me if I can use 7 tcu dies or do I need 7sm dies ?
Is the 7sm easy to form and load ?

7 SM
PJ,
You will need to get a set of 7SM dies, mine are Redding...... 7TCU dies won't work.
The 7SM is no more difficult to load for than the 7TCU......piece of cake.
