About to build a 330 Whisper

[daveosok]

I will receive my donor action here shortly either by weeks end or early next week.

I have opted to rent the reamer as a call to my favorite reamer maker netted 8 to 10 weeks for deliver. This is just to long of a time frame so I will rent it.

The 300 Whisper is of course a SSK propitiatory item therefore only they will have exact 300 Whisper dimensions. The reamer in question is actually called a 300/221 fireball and will work with the Redding Dies that also read 300/221 fireball.

Do you have any tips before I embark on the chambering? The barrel has already been contoured and lacks chambering and threading.

Just wondered if there were any tips, tricks or secrets I should know about before finishing the chore.

Its a Pacnor 1:8 twist and a rem 700 action. The reamer comes with no freebore only a throat. How will SMK style bullets seat with only a throat or do I need to add freebore to it with my throating reamer?

Up next a 338 Whisper in a 1:10 twist or should it be a faster twist?
