See above comments for remedy.

If the base needs sizing, I've heard that stripping a 45ACP sizing die will allow you push the case all the way thru. Carbide will be easier. Not sure if I'd do this to a loaded round..


I just used a sharpie marker and painted the entire case and kind of what I suspected the problem is on the shoulder of the case. My COAL is good, base of case is good, I saw contact markers on the shoulder of case. Is there any way I can bump that down with my die? I thought when FL sized my case that it was automatically bumping the shoulder back. As another amp fire member said I may just have to buy brand new brass. Or I may be able to fire this stuff through my chamber to get it to fireform to my chamber and continue to use it.


It's hard to tell from here. The die isn't sizing enough for whatever reason.

Or it is sizing enough & when the expander is pulled back thru the neck it's stretching the brass. Some Federal & Winchester brass are fairly thin. I've seen this happen a few times.Take out the expander assy, try sizing again, then chambering. If it fits easily without expanding polish your expander ball &/or lube inside necks with powdered graphite/motor mica/some other type of dry neck lube. Redding sells Imperial sizing wax & dry neck lube these days.
