Do you deburr primer flash holes on new starline handgun brass?
I do it on all my new bottle neck rifle brass
Just deburred my new .44 spl brass. There were some burrs in them

Interesting. Only ever deburred and chamfered surplus MIL brass (556/762).

All flash holes are punched so all will have burrs. It’s debatable if it improves rifle loads and won’t have a measurable effect in pistol ammo.

Never on straight walled. With Starline I check fladholes before ever sizing. Had some w/o flash holes.

I do it, but mainly because it is just what I've always done to my rifle brass. I have quite a few different tools for this but for revolver brass I use the K&M tool. All of the auto brass obviously doesn't get this treatment. I'm anal, not stupid (supposedly).
I don't know what slight difference it might make, but it's a one time deal and I have the time. I only keep 300ish pieces of brass per caliber of revolver so it doesn't take long and that time has been spread over a few years time.
Necessary? Absolutely not, but I also try to keep the brass at the same length for consistency sake. I'm am not a high volume shooter with the revolvers and 100 rounds of that stuff at a time is about all my nerves want (its 95% off of a rest trying to put all of the bullets through the same hole).
Well, maybe I am stupid after all.

I uniform primer pockets, and deburr and uniform flash holes on everything I load.

ONE REASON I LIKE STRAIGHT WALLED REVOLVER CASES IN REVOLVERS IS THAT I VIEW IT AS MOSTLY A MASS PRODUCTION RELOADING EFFORT, NO DEBURRING, TRIMMING, WEIGHING EACH CASE OR CHARGE, etc. JUST RESIZE, PRIME, BELL, DROP POWDER, SEAT THE BULLET AND CRIMP.

Wow ! Opinions, thoughts vary widely. Magman finding some cases with NO flash hole...gonna start looking now. I've cleaned flash holes, but haven't religiously deburred upon buying.

I have also had starline brass without flash holes.

Do y’all size new cases? I do with the decapping pin in place so missing flash holes will never bite me.

Always size capping pin in place. First time I wasn't smart to figure out why I broke a decapping pin, then I looked inside.

Maybe not resize, but definitely expand them. I have a habit of looking at every case as I prime them. I treat my revolver ammo like I treat my rifle ammo, cases from the same lot, etc. Like I said earlier, it's not a volume thing with my revolvers.
Now with 9mm and 45 ACP that goes in the Dillon's, not so much. Since each case has been fired before and is tumbled, I cheat and load them up.

I tested Starline 357 Maximum brass with and without deburring and could not find a difference in accuracy or extreme spread.
