Ok I picked up the wrong bag. now knowing the there is difference in the 2 cases. here 's the plan,bottom of the Sierria charge list (61g of H1000) a 175g sierria SPBT, set as far out that can be still held in the case.
In my little mind; the bullet should hold the case back agianst the bolt face, like fire forming for the Ackly's, and the shoulder should move forward??????

Should work, but I'd use the fastest powder listed for the 7mm WSM. I'd worry about funny pressure excursions with H1000.

isn't the 7wsm shoulder slightly different than the rest of them, to prevent you from closing the bolt on a 7 in a 270?

(chekcing ammo guide)

7wsm shoulder is at 1.701
270 is 1.664 ..

.037 "headspace? ... you could get casehead seperations, i would take them back, or sell them here on ar
