I've got the B14 Ridge in 300WM. I've been cleaning mine after every 5 rounds (load workup) and after settling on a load the groups with each shoot/clean cycle have been getting tighter. Mine will change group location depending on what type of brass is being shot, so recommend sticking with one brand of ammo or one lot of brass if reloading. As for ejection issue, I'd check for a burr on the raceway (I think its unlikely but never hurts) and then the ejector to make sure its functioning properly. Good looking setup!!
