6 Creedmoor reamer specs/Berger 109 LRHT

[707electrician]

I know, generally speaking, this topic had been beat to death but I have not seen any posts on this specific combo.

I am about to start ordering parts for a new 6CM build and I am trying to figure out what reamer specs would work best for the Berger 109 long range hybrid target. It seems that the .183 freebore is common, however from what I have been reading, this may be slightly longer than desired.

Ideally I would order the brass and bullets and just load up some dummy rounds to figure it out, but given the lack of components these days, I can't do that.

If anyone has run these bullets, let me know what your chamber dimensions are, and how it has worked out for you.

I know what you are going through. Go to post #9 in this thread and click on the link. After finding these pics I went with .123 on freebore.

6mm Creedmoor Freebore

The folks doing my 6mm Creedmoor barrel have two reamers both 275 neck and a 123 or 190 on freebore. I want to ask the experts here for their opinion. The bullets I intend to use would maybe be Hornady 108 eld 107 Smk 105 Hornady match and maybe 95 Smk or Berger Kind of the same bunch or...

~.120 fb is perfect on anything from 6br, 6x47, or 6 creedmoor with the 109s.
