I would say it’s worth it on Hornady and Starline brass. I never had a tool that would fit the Lapua brass, but it always looks pristine in there. Hadn’t noticed burrs In Peterson either, but under magnification it looks kind of chewed up a little on their finishing job.
Is deburring flash holes still a thing?

Good to know. What brand of brass are you seeing this in?

I segregated the unexplained flyers at 1300 yards. Borescope showed a burr inside those cases. It eliminated that issue. Lucky? Maybe. But they all get it now.
I have uniformed flash holes on new brass just to eliminate variables for a long time, but I do it for an additional reason anymore. On small flash hole brass I broke a depriming pin one time on FF brass before any prep so decided to deburr just to make that pin find the hole just a little easier. So far that approach has been 100% with not even a hint of the pin missing the hole anymore.

Lits just posted about flash hole deburring on the FB . Showed SD reduced a little bit.
If you flash holes are punched and not machined I say do it. If nicely machined appearance maybe not. No Bench rest guys. well even the F class may but most are buying high quality brass.
Here is a partial snag of the post

I do believe in Captain Crunch.
This is the reloading tip the I needed today. Thank you!
Which one do you deburr?
I’m guessing twice as fast.

What did Remington use to punch out the second hole from the mouth of the case? Flash holes are punch/machined from the base/pocket?

They were factory Remington 150 Core Locked and they shot around 4" at 100 yards, horrible but there was no RUM brass to be had anywhere a few years back. I shot one box then pulled the bullets in the other 2 boxes. I use the Harvey deprimer and it is almost impossible to get it in some of these flash holes, seriously, these were like no other case where it pops right in to the flash hole. So yes I certainly deburr RP cases
I did it to each round I was reloading that was how I was taught and it didn't add that much extra time to the process. The folks I reloaded for appreciated how thorough I was when reloaded their ammo! But, that may just be me and how I do things...
I set 250 starline 556 in trays and looked in them with a flashlight when new. I could see a few with burrs. I should have marked em to see if they caused a flyer. I think I ended up doing nothing to them.
All my other brass I deburr. Probably cuz im bored mostly.
I have seen several things about uniforming the pocket making things worse recently. There was a video by the primal rights guy on the subject and a few others. I'm not uniforming pockets now, and I see no difference so far.
Of course, I'm not shooting benchrest of F-class, Just bustin PDs and shooting steel alone in the desert.

I'm curious what problems uniforming pockets caused? I use the uniformer after every firing to clean the primer pockets if I am not tumbling. Sometimes it takes a small amount of brass but usually just the black stuff. After several loadings I still don't have loose primer pockets.
It increases primer seating depth variation.
That seems counterintuitive. Any idea why that might be happening?
The tools do not index off the critical spot.
I am pretty sure it is discussed in this video.
