300 prc perfect throat length??

[Dave McDowell]

I got a question for the experienced smiths on here bout the newish 300 prc throat dimensions. SAMMI calls for .233 freebore but inwas wondering if anyone has found a better length. My smith is wanting to get the correct reamer. Most likely I'll be running between 210-230 grain pills. It's a krieger 9" twist and should have a finished length of 30". Any input or experiences would be much appreciated.
Thanks
Dave
