Ok...so here's the skinny: I took once fired 223 match brass, cleaned, fully resized, trimmed, reloaded and then shot in my 223 Wylde AR. After doing that, I cleaned the brass again...and now want to neck size them only. Is this correct? I know neck-sizing is typically for bolt action only, but I also thought that it is good to go IF (and only if) you shoot it in one AR, then neck size it and only shoot it again in the same AR again. Also correct...or incorrect?
