I have a savage 110 action that had a blind stagger feed magazine. When i load the first round in the magazine it will not stay in. Also when I go to chambered a round it wants to hit the end of the barrel inside the action. The magazine has a new spring and follower in it. The gunsmith lost the original one and had the put a new one it. I never chambered a round before I took it to him, Therefore not sure if the issue was there before or not. The rifle was a .270 originally and i installed a .280 ai barrel from mcgowan on it. Any Ideas on a fix? are there aftermarket magazines that will fit and maybe work better. I don't really want a single shot as this rifle was built for hunting.
