I’m looking at a national match / precision krieger barrel. One chambered in house at Krieger is a little more expensive and longer lead time than an in stock WOA Krieger NM.
Both Krieger blanks obviously, how much difference in which shop does the finishing work between the two?
If the question is can a poorly cut chamber be bad for accuracy compared to an identical barrel with a properly cut chamber, the answer is yes it has a massive impact.
If the question is does WOA do a good job? The two I’ve had were tack drivers and were done very well.
I have 2 WOA barrels a Shillen and a Wilson both are very accurate and a 6.5 Creedmoor AR-10 Kreiger from Fulton Armory that I believe is a Kreiger chambered barrel. I shot a 7" five shot group at 1000yds Saturday with it. I would not hesitate to buy from WOA again. I just bought another Kreiger from Brownells on sale the other day for my kid we haven’t even shot it yet waiting on other parts to get here. I really don’t think you could go wrong with either company chambering the barrel.
To my knowledge it has never been shown to definitively matter. My guess is that if it does have an impact, it’s so insignificant that it’s practically immeasurable or that such a small number of people are good enough to see that difference that it’s irrelevant.
Kreiger makes great barrels. Kreiger does that. They also prescribe a lengthy break-in procedure that is of dubious value too…
None of that harms the accuracy, but I’d bet fairly large sums of money that everything else they do is far more important.
