How often should you bump the shoulders when your resizing brass? Specifically brass that has only been shot in the gun your reloading for.

After every firing. You should be annealing too, to keep neck tension consistent.

To keep them consistent every shot, and know they will feed every shot. It's .002". Less than a human hair. Brass isn't being ruined by sizing that amount each time.

Every time, anneal, FL body size and mandrel for neck tension.

If they start that short and are not expanding into your chamber to be tight you will have head separation problems sooner than later. Something is wrong with your chamber specs or the brass to begin with. Even if you bump .005 or .006 you should get a tight bolt close on a fired case, if you're not I would be concerned.
I do it every time but that's only if the shoulder moved enough to be bumped back. I measure with a headspace comparator on my new brass, record that number and then again after I deprime, but BEFORE, resizing fired brass. If it didn't grow, then I just set my die to leave it as-is. I adjust as necessary on future firings based on how much it grew and if a fired piece won't chamber or is difficult to chamber.

Until u go hunting and can't chamber any or very few. I speak from experience when I was very young and had little reloading knowledge. Everytime for me. And I run every hand load thru my gun before I put it into my hunting round box.

If you're not running hot and extraction is easy don't worry about it if you don't want to. As you can see people have a difference of opinion on this old and tired argument. I'm seeing a lot of tier 1 shooting advice that the average reloader is going to get lost in all the other noise in the process.
