FL sizing help needed

I’ve recently started FL sizing some once fired 6.5 Creedmoor brass to get some practice (wet tumbled with S/S pins and then lubed).

I’m having an issue with the Hornady Custom grade sizing die scratching the cases. I’ve used a cleaning brush with fine very wool wrapped around it + metal polish, and then a cotton polishing pad on dremel - the inside of the sizing die looks polished (but difficult to say 100% without a borescope).

I’m using a 99.9% IPA/castor oil mix for lubing 10:1 ratio, spray the mix into a ziplock bag to distribute.

I have the same issue with my .223 Lee precision FL sizing die so I’m finding it hard to believe it’s the dies causing the issue. Funnily enough my .44 mag sizing die doesn’t scratch the cases one bit and I’ve never used any lube??

Any tips where to start diagnosing the problem would really help before unleashing onto Lapua brass 🫣
 
I'd agree with @finnbear270 , dent in case would suggest too much lube in this case, try using less lube or lube differently, I'd also give the die a good clean with brake/clutch cleaner, as metal polish is abrasive, you may have left some in there.
Just to add, I'd still use the case as it is, as it will blow out when fired

Is the shoulder dented on that case?, or is it just the way the light is, looks just like over lubing dents to me.
Do you possibly have a bit of grit in the lube, is the scratch in the same orientation to the die position every time?

I see what you mean from the photo but no it’s not dented just scratched, scratches are the same direction vertically of the die.

Is the die, or the case holder off centre in the press???

Initially this was my thought! But no it’s straight by eye however with such tight tolerances it could be the reason. Cases were very clean, they had been through a wet tumble so no chance of any dry media being on them either
 
I spent £10 may be less on a tin of imperial resizing wax god knows how many years back now, can't understand folk making their own to save a couple of coppers.
Re marks on case's i give all dies a polish with some 2000 wet and dry (you can put some of your concoction on it)
Edit i see you have polished your dies..
I polish all.my dies ftom new.

To be honest it’s less the cost and more the time it takes to individually lube each case

What do you attach the 2000 grit to?

I rub my thumb and index finger in the wax (kept in fridge) grab approx 9 cases and rub the case's around before adding into shell holder.
The necks every other 1 get a lube with a cotton bud dipped in some 15 year old one shot.
