300 PRC from 375 Ruger basic

[cwtebay]

I recently purchased some 375 Ruger basic from a member here with the intent of reforming (forming) it into 300 PRC.
The brass starts at roughly 0.53".
I have: 45-90, 43 Spanish, 44 WCF, 405 WCF, 401 WSL, then it's a sharp dive to 375 H&H, 35 WCF, 338 win mag, 32 special.....then I head to the 30 caliber.
I have already run 10 through the Annealeez - suggestions from there?

May want to hold off on the annealing, annealing before forming can get you crumpled cases.

I have no idea what the case you're aiming for looks like, I just know annealing after has almost universally been the way to go.

I think the only exception has been fire forming 7mm Rem Mag to 458 Win Mag in one poof.(I think)

Thank you for your help, I have to admit - struggling on this one!!
