I've used many ER Shaw barrels. Initially because they were cheap. Two of some of the early barrels that I used had 1/4" cavities inside the barrel. Since then, 1970's or so, I've had no issues with their barrels. Similar to RWE, they made rifles that were accurate. Never had one of their rifles though. I'm not a fan of Savage bolt action rifles, a lot of people are though. The ER Shaw rifles do look nice.

I prefer classic.
