RE: stainless vs blued
Straight from Kreiger barrel website. Now, I couldn't see all that much more time for stainless. But these are the barrel folks.
Q: Which is better Chrome Moly or Stainless Steel?
A: For the most part neither one is better than the other. The only difference we find is that sometimes the chrome moly might take a little longer to break-in and might have a little more affinity for copper or seems to show it easier. In terms of barrel life and accuracy, we can find no difference
