Hey yall. I have recently bought a weatherby accumark in 30-378 and a mark 4 6x20 leupold scope. I have mounted the scope and it wont bore site. I have used leupold bore sighter and done it manually. I cant seem to get the crosshairs low enough. I have checked the rings (removed twice), the rings are for weatherby mark 5 dual dovetail. High rings. I cant think of anything eles. It looks like the back base needs to be shimed? Please help....I am lost.....
