If your 300/221 resized cases are that much different from the 'factory" ammo and fire formed cases then perhaps you would prefer the true 300 whisper dies from SSK Industries.

i don't know if this is true...someone told me
ssk spec 300 whisper cartridges will chamber in generic 300-221 chambers
BUT
generic 300-221 cartridges won't chamber in ssk spec 300 whisper chambers.

I think that is exactly what I need to do. The corbin ammo was stamped SSK 300 Whisper. I guess they use the SSK dies I would think. Thanks to all for helping.

Ok. Got my dies in and some SSK brass yesterday. Loaded up the exact same load in 10 rds of my 221 brass and then 10 rds SSK brass. I ran my 221 brass through the new dies and it seemed to smooth out the shoulder a little, but the shoulder is still a little sharper than the SSK brass and the corbon factory ammo. The SSK brass I loaded looks exactly like the corbon ammo. I hope to find out when I fire the 20 rds that it was in fact the redding dies shaping the shoulder curving too sharply instead of almost sloping down to neck dia. This would make the part that touched th echamber too far forward and not chamber. I'll let you guys know after I shoot them and what I find out.

It was the redding dies. I made some rounds from both my 221 cases and the ssk brass, and used the new Hornady dies form ssk. It functioned flawlessly. Not one single failure! Thanks to everyone that help me sort this out.
