Ugly. More ugly as a muzzle end than a breech end, due to the very shallow angle at which the lands were graunched (chewed) at. Then there are multiple detail cuts that should be sensible and seamless, rather than pointless and stepped.

The red line also points at a huge burr, that repeats on the one side of the other visible lands.

exactly.. I have recrowned a few barrels in my lathe and I really like to spin them up and use a die grinder on the tool post with a very small stone.. very smooth and definitely no burrs.. that looks like it was done on a lathe with way too heavy cuts and like made burrs that definitely should have been cleaned up on another pass..
very rough looking.

Heavy cuts, and or a dull cutter or reamer; either or both a very shallow angle.

most likely all you said combined.. also looking at the end face of the barrel, not that it matters a lot but it looks rough and poruis.. like a snow peak barrel I recrowned.. I mean if you are going to do a job, might as well have a mirror finish.

This reminds me of when I was a manager at the Outback. My manager would whine non stop about the ‘numbers’. He would get so pissed at me when I responded, if I take care of my employees and customers, the numbers will take care of themselves. People aren’t dumb. They know when someone is cutting corners.

I haven't seen an imbalance shooting those pellets, it should be noted that my first paper at 100y was of 220 points with this barrel, like that. While more I shoot the better it will be. Pellets taken from the tins, and shooting 935fps, 2150 R1, R2 2700, transfer port open. Good job for Donny and AEA pellets.

Donny told me that that system is normal, and that his barrels are configured like this to win.

I just wanted to be sure if it was normal, and the company already told us that it is normal.

Thanks guys for u support.

Shooting that well with damaged rifling at the muzzle is impressive. Meaning there is potential greatness left on the table to leave it as is.

Or to say it differently, it is true some barrels shoot quite well despite machining defects. It is also true these same barrels shoot better still with the defects corrected.
