Breechplug,
Do you shoot conicals from your Accura? The reason I ask is because I wasn't aware the Bergara barrels were button rifled. The Kodiak Pro and Win Apex I own are both cut rifled. Regarding, SS coating, I can tell you these two stainless barrels are solid stainless. They aren't Bergara but they do shoot well. Particularly the Win Apex which has a better trigger. Its not uncommon to get 1" groups at 80 yards open sights. Its tough for me to point MOA beyond that distance with the factory sights and there is typically wind here so things tend to widen beyond that distance.
I do like cut rifling for the conicals though and am curious if you have tested any full bore conicals in your Accura.
