A new question that I should have asked earlier. When only collar sizing the .303 brass, do I wind down the primer pusher on my original die or would you recommend a separate primer remover or a separate collar only die?
Thanks.
I bought a Neck Size Only die for my 303. Made by RCBS. I am sure you can adjust your FL resize die so that only the neck portion of the case gets re-sized. As long as the de-capping pin (primer pusher pin??) extends throught the flash hole far enough to push the primer out, you should be OK. If it doesn't, then, yes, thread the de-capping rod assembly down until the pin pushes the primer out.
