358 BFG-WSSM $150
The 358 BFG-WSSM dies will work with practically every 358 WSSM variation that I've come across that uses unmodified 25 WSSM headspace dimensions.
358 Gremlin-Grendel $150
The 358 Gremlin dies will work with the few "copycat" chambers out there based on the fired brass and chamber prints that I've been sent, provided the headspace & body dimensions remain unchanged from the 6.5 Grendel.
