I've got a Redding FL type S die (.308) that I started prepping brass with. I've got a Wilson case trimmer with the "new" 308 brass case bushing per Wilsons information (full length sized brass uses the same bushing as new). When I slid the brass into the bushing, it didn't fit.
Long story short, the shoulders are wider than an unfired manufactured round (.453" sized vs .450" unfired). I've tried sizing without the bushing, without the expander ball inside (just the body die), and adjusting the overall depth but it didn't affect the shoulder width any more. Does anybody have a similar setup that had the same problem? It's still within spec (.454") and they were fire formed to my rifle (bolt-action), but my understanding was that it should've brought it to unfired spec.
