25 wssm brass fire forming

[matt bradley]

I just bought a 25 wssm and can't find ammo or brass for it, if I find 223 wssm or 243 wssm ammo how do I "fire form it" ? Load and shoot? Or pull the bullets and resize with my dies, I could use any info you guys have .
Thanks

I would keep looking for 25 WSSM brass, and leave the 243 WSSM crap alone completely. Had both chamberings, the 243 WSSM brass would crack shoulders and neck, annealing did not help. Had no problems with 257 WSSM brass.
