I spoke directly with the Bergara US head of sales last year
We discussed several rifles we returned unfired due to bore “issues”.
Arguably some is just carbon but there are several occlusions, voids and crystalline structure anomalies
His response was an ill advised shift to a cheaper steel provider which they will probably still be recovering from
Almost exclusively 2020-22 products
These are brand new and aside from proof rounds, unfired.
The quality now is much better
But anything when abused will erode/corrode and produce internal anomalies that MAY impact accuracy
The last video is my second hand 308 barrel with several hundred if not thousands through it before a very nice chap rechambered it into 300Norma
I proceeded to put at least another 6-700 rounds through it pushing 200gr ELD-X
It shot 1/2 MOA all the way out to 1000m until I put the 338 back on and got a new 300nm.
It shows that surface quality and anomalies don’t always have a downtange inpact
Some do obviously
Bergara #1
Bergara #2
My 300 Norma 1/2MOA Sako TRG42
“Dirty”
“Clean”
