On a short action 700 when I eject the fired case It will move part way before clearing and act as such it has cleared the ejection port when not fully cleared and leaves a engraving mark on the neck if I do not manually guide the case until it clears the port. It does not do this on a 308 case, only the shorter 6.5 x47. Any ideas. So it appears the case is acting as it is ejecting prior to clearing the port. Also the same with a loaded round.
