Opinions Requested....What do you make of this?

Bench vise is a must lol, the first one you do it’s prudent to take your time and periodically drop a shell in and take note of rim placement/position. Or put the barrel in the receiver and check how it all looks, easy after that.

Same as throating and polishing the feed ramp and chamber lip on a 1911, it made a huge difference in how reliably 12g shells fed from a mag fed Grizzly. The box mag doesn’t have much room for 3” shell oal and it got blended a bit as well.

If you have a drill press or milling machine, bolt the vice to the edge of the table, clamp the barrel at the angle you desire, then use a cutting tool in the chuck to "cut" that profile. Many 870s and the old 1100s will often fail to feed with some ammunition because of the relatively small bevel from the factory.

Nice job by the way

Forgive me, but where is the OP's chamber walls uneven? I'm not challenging the assertion, I just don't see it.

It’s pretty wavy looking, not smooth and mirror like. May not be an issue but it might cause extraction problems on certain ammo, I’d expect better on a brand new barrel.

I can deal with a bit of polishing or de burring if the price is right but I’d complain if that showed up and I paid top dollar.

That would work too, I prefer the hand touch for things like this. Even a bit of emery cloth wrapped around a dowel would do the job well, I find it satisfying to work with hand tools still.

Hand work is ok until motorized tools, such as Dremels get involved.

Maybe you've been lucky, but many of us here have had "slips" that leave a very nasty and often impossible-to-remove "scar"

Setting up the drill press or milling machine eliminates the possibility and ensures even angles every time.

You did a great job, so I'm not dissing you.

But when you've done several dozen such jobs, then you try to eliminate as many variables as possible

I wouldn't call it lucky when an engraver makes thousands of cuts without a single slip. It's skills and ability, experience and dedication to perfection.

Not every one has it.

Oh I get it and I didn’t take it as a diss, I’ve had my fair share of slips over the years. One of the reasons I mainly work on my own guns, if I slip it’s only me I have to answer to. I have one or two close buddy I’ll do things for but they’re up to speed with this part of the deal, thankfully.

Usually the scars end up on my fingers lol. Ended up with some stiches the other summer after a little bandsaw slip, got lucky with that one. Was my trigger finger too boot.

I took a much closer look at my 14" Dlask, and aside from the seam joint where the barrel and trunnion meet (I didn't even know it was two piece), all is smooth in the chamber. As smooth as one of my older 870 barrels I compared it to.

So I just picked up this brand spanking new shotgun barrel, and I would like the communities opinion. I've never seen this before, have you? What say you? Take a close look at the chamber edge, where the shell rim should sit.

If it was crisp and sharp, shells would catch on it. Shoot it; if it operates nice, it is nice. If it does not (and a lot of semis don't) it is a problem.

Every manufacturer has their bad pieces, it’s how they deal with it that matters.

I hope Dlask swaps it out for the OP, they screwed something up for me and in all fairness I should’ve open up the package before I walked out of their shop. They totally took care of it for me though, which is the nice part. This was back when Leigh was there though, maybe things have changed.
 
I suggest you shoot it and if it does not function correctly address that problem with the manufacturer.

It could be perfectly fine and you maybe trying to fix a non existing problem.
