Does all fired .223 and 5.56 brass get slightly enlarged after firing at about 1/8 of an inch below the extractor groove? I assume this is a result of the brass expanding against the chamber.
The reason I am asking is that the fired brass I have (Q3131A1 winchester) has a shiny ring in this area. Brass from other rifles (not Q3131 A1) has the enlarged brass area but it is not shiny in color. I have to look at the brass pretty closely to see this. |
Thanks for the insight!
