I'm circumventing any OAL issues by re-barreling a 700 long action.

I called the smith in the link and talked freebore with him before ordering a reamer. He said suggested the .188". My 6.5-284 happens to have a .188" freebore, so I seated dummys in that chamber, and extrapolated seating measurements to the PRC brass.

The 147's are a loooong bullet, and probably need .080-100" over a 140 VLD. I didn't want to be hamstrung throating strictly for that bullet, so settled on seating depth for the VLD's and I'll just seat the 147's deeper. Mine will be around 3.025" or so OAL with the VLD's, as I bumped the freebore to .200" even..
