Reloading for a match chamber in .308

[YOTESHOOTER]

A suggestion, turn the necks of the brass, what type of primers are you using, BR-2, GM215M match primers?? These are things that can help the groups, even a .5 grain of powder one way up or down can also help with accuracy also. Just depends on what you personally want. However, would suggest only change one thing at a time and document the change and the results helps keep down confusion, and frustration.

just some simple suggestions to consider...

Sounds to me like its chambered for the lighter bullets. If it is chambered to 155s, its nothing to take a 175 reamer in and throat it out. Takes about 5 minutes.

Most Palma I've seen is 30"+ 12 or 13 twist throated for 155 bullets. Usually bergers.
