Agreed, best practice is to follow the rifling. I assume Ernest says the same nowadays but he actually did a how-to video a few years ago showing spinning the barrel in a lathe.

fx barrel defect

yes, I also read that I needed to follow the grooves, but since I lost my love for the barrel, I used the drill to be more efficient

before polishing I passed a slug through the barrel, the beginning was absurdly tight, in the middle there were tighter areas and others looser and in the end I couldn't pass the slug, I even had to push it in the other direction because it was already bending my rod . After polishing, it remains tight at the beginning, in the middle it became more uniform and after a lot of force I managed to pass the slug completely

Yes, he spun it at the very end of the process if my memory serves, given that the FX barrel doesn't have lands I don't see why it would matter. I've looked down my barrels after a couple of thousand rounds and a good cleaning and they are mirror smooth, I've got a bore scope coming in to verify that. I'm not sure how far down that branch of the Rabbit Hole® I want to go for a few hundred more FPS on guns that are rarely used over 30 yards. Except on ground squirrel days when it's 70 yards.

You're right and it was only with the finest grit, though the barrel he's demonstrating on is not an FX. Possibly one with a similarly soft rifling profile (e.g. polygonal)...I rewatched the video but he doesn't say.

I feel that the quality of FX liners is not consistent from part to part. No manufacturer's barrels are, but I've seen some wild differences in FX barrels.
