That was quick.  And now for the coin toss - Creedmoor or GT?

Those darn 5R barrels have a tendency to make reamers chatter …
- why (preemptive strike for people that want to tear things down as whinny children instead of helping others)..
Because the incline on the side of the rifling makes a ramp surface contact point when the reamer engages it - this pushes the reamer (chatter baby), on normally rifling the reamer flute hits the side of the rifling edge cleanly without having to dig into a raising plane surface… ]
Frankly I had to be told to look for it before I noticed it… But I had a great teacher so … Meh…
Meaning it is hard to see if you are not looking for it closely - even then … old eyes, ….

With an even number of lands the reamer is cutting a land on each side simultaneously. That is not the case with odd numbers of lands/grooves and the side doing the cutting tends to deflect without support on the other side.

Guilty as charged. A friend just helped me contour and chamber a replacement barrel for my favorite 6.5-06 a couple of weeks ago. You will like a 5R barrel, they clean up easily and seem as accurate as my 4 groove Kriegers.

Bart #3 at 20 which will allow for 5/8x24 thread with adequate shoulder. That’s the current plan but plans change….
