Guys the bolt on my Howa .308 Win is sticky as hell after firing. This is happening both after firing a live round and dry firing. Its also shaving a bit of brass off some of my case heads. Ive taken it apart and cleaned it well but its still rough on the up lift. It does not do this if the bolt is cocked only when fired. Any ideas?gun)This is happening on factory rounds as well as my reloads as well as with nothing in the chamber.
