I'm FL sizing some 300 rum brass for a friend, Norma brass once fired, using a Redding type S match bushing FL die and using hornady one shot spray lube. Cases were harder than normal to resize, and now they look like this. What's my problem here?
How do you polish the die?Check and polish your die, if necessary, and get some Imperial Wax.
If that doesn't work, I'd explore his chamber, to see if it's oversize.
I did not let the one shot dry on the brass, but I did clean the brass in a sonic cleaner before sizingAre you letting the lube dry for a while? I've only had issues with one shot when it was wet when resizing. Moved to lanolin and alcohol with zero issues.
Also, good to clean brass before resizing.
