I had asked you about the BAR (280 Rem) thanks for the clarity. I am sticking with the 270 WSM and my 300WM , the WSM may need a new barrel next spring, we will talk. Nice work on the Kimbers.
A boring bar will cut to the axis of the machine. If your barrel is co-axial with the machine, you will get a hole which is perfectly aligned and concentric. Now, most barrels are not perfectly straight, so you are going to have to decide where you compromise and how you align your barrel prior to boring. Generally speaking, a properly ground drill will follow the bore but, if the drilled hole is not concentric, a boring bar will ensure a straight start. However, the barrel has to be precisely centered to bore a concentric hole. For BR barrels, I will dial in at the throat, then bore. Technique will vary according to the intended use of the rifle. WH

I only had to send my kimber in 204 back 4 times to the factory to get a good group out of it. Lol
Early on, they had some real QC issues. They're pretty good now and I kind of like them. WH
I've seen other gunsmiths that run a boring bar in there between the drilling and reaming steps. What's your opinion on this procedure?
