I have had very good luck with Sako and Tikka rifles in the accuracy dept. They do seem to have very smooth barrels. They dont copper foul and seem to clean up very easily.

I have an older Remington 700 that is equally as accurate and smooth. But have had others that were not.

I once had a Weatherby mk5 375 H&H that was aweful. It wasn't accurate with any load. And also had a rough bore. I'm talking 3" groups at 100 yds. I also had another MK5 300 weatherby mag that wasn't much better. And one in 7mm Rem Mag that shot great. So go figure.

I have a Ruger Hawkeye 375 that is very accurate. It's barrel seems to be smooth. And come to think of it, I've never had a Ruger M77 that didn't shoot at least decently. And I've had a few.

The Winchester model 70's that I've had have never dissapointed in the accuracy dept. I did have one in 270 that was a little sloppy in the action. But it was one of the last of the ones made before the reconstrution of Winchester a few years back. Their current rifles are jam up though.

So I guess all manufacture's have good and bad days.
