6.5 284 reamer

Can anyone tell me what freebore length I need to shoot the Berger 140 out of the 6.5 284 Norma and keep the bullet bearing surface from going below the neck shoulder junction. I did some math and .188 looks to be good but can some one verify this before I order a reamer.
Thanks Dustin

Yes.. You over-shot it by a little. A .170 freebore is just about perfect.
