Did you trim the brass after you resized it?

3% offered good advice.
Get yourself a Hornady Headspace gauge. Very easy to use and helpful tool.
Don't mix your brass.

What lube are you using inside the case necks? I n the past, with a rough expander ball in the sizing die or not enough lube in the neck, I have pulled the shoulder angle forward when withdrawing the case from the die. A good idea is to use a brass brush (dedicated just for this purpose) to clean residue from the neck.
Remember: It aint what you shoot...it's how you shoot it.

Hmm only 30 thousandths back from lands? I'd bet a little more jump will fix the issue.

A “tad” isn’t a measurement. How much did you bump the shoulders back on each piece of brass?
Also if your lube was inconsistent from piece to piece, your shoulder bump may be also.
You're only as good as your worst shot-

Sounds like some shoulders were bumped a “tad” while others were not.
Definitely need a comparator to measure shoulder bump.
In consistent lubing equals inconsistent shoulder bump. Shoulder bump will also vary between different brass manufacturers or lots, with no adjustments made to the sizing die.

Check case size where it hangs out of the gauge then measure one that fits

Good point and you could be correct. I do have a comparator that I used to measure the length to the shoulder before and after resizing. I didn’t find that the measurement increased so I did not set the die to bump the shoulder, at least according to my notes. I did take measurements of a few and average them so there could certainly be outliers. The good news is that I have a ton of brass that I have FL sized and the rest fits in my case gauge after resizing now. Just want to figure out what happened with these particular loads.

That gauge you are using is only useful for semiautomatic pistols and semiautomatic rifles when you are wanting ammo to fit several different firearms .and if ammo isn't sliding into gauge you didn't size enough.its that simple When you mix brass it takes different amounts of sizing to fit it back to your chamber.
So basically with what you are doing with the mixed up brass just completely size down to shell holder to use up that brass or you at least need to size a good 4-5 and check in your chamber for tight bolt.just for blasting ammo or just good enough hunting ammo they will work fine
But in future get the hornady headspace comparator to bump shoulders and keep up with your number of firings and start with new brass if precision is what your looking for.if your just looking to use up once fired mix match brass fired from a different rifle just size to shell holder and be done .no since in fighting it .you can't size mix match brass the same without oversizing all of em

Honestly bud read several reloading manuals and load ammo by the book.then start watching panhandle precision or other vids You got to know basic fundamentals and safety to start.if you had read reloading manuals and set up your dies per instructions you would not be here asking questions. You mentioned panhandle precision.great vids but that's advanced you need to know basic knowledge of hand loading.the same understanding we all know and will give you confidence and basic knowledge But read 2-3 reloading manuals.read front to back for safety and basic knowledge we all know Your question you just asked would not be have been a problem if a you had done so.now this is where you start learning advanced hand rolling .interwebs .lol

Not saying this is the problem or to be mean spirited but did you lube a little bit heavy? Yes I've done it myself more than I should but lube can dent a case in a heartbeat.
