If people used borescopes before they bought factory rifles, they would never buy them. There is an
excellent video that demonstrates the typical Remington barrel compared to a custom lapped barrel.
It doesn't mean they won't shoot, but it does show that "breaking them in" is basically futile. Chatting with the guys on Team Savage, they said that Savage barrels are pretty scary to look at too.
There is no difference between the barrels used on the Cheapest SPS and the most expensive CDL's or 5r's; they're all crudely machined.
That's why I think it is a waste of money to buy expensive Remingtons. For barrels that are supposedly hammer-forged, they sure are shyte compared to Sako/Tikka
