[QUOTE="midgetorama32, post: 370145, member: 19282"] Thanks very much Fiftydriver for that post. I played it with it some more last night and here is what I have found so far... 1. Some how, some of the bedding compound "repositioned" itself in the lug area when the action was out. I used Devcon and can only think that I may have not mixed enough and some of the compound that didn't have enough hardener finally began to set up. When removing it, I could have sworn it was still a little bit gooey in one area. The recoil lug has been completely relieved now on all sides except the back. 2. This is what concerns me most. I layed the action in and tightened it down slowly, when the front action screw was tightened, I could visually see it pulling the action down further into the stock. Using a dial indicator, it told me the action was moving another 0.020" as the screw was being tightened. At this point I got ticked off thinking I had to re-bed it so I took the scope off. When I loosened the front screw again, I got no deflection at all. This was with the NF base still screwed on. I stuck the scope back on and again I had 0.020" of deflection. I read somewhere that NF rings didn't require lapping so I never lapped them or even thought about it. However, when I used an alignment tool, the rings were way out of whack. I lapped the heck out of them and the problem went away. No idea why it wasn't a problem with the EGW base unless it's because it's not nearly as rigid as this NF base and wasn't stressing the action as much when the rings were tightened down. I am considering bedding the base as well. 3. The muzzle brake has a teeny little imperfection at the crown. It's just barely visible to the naked eye. It is something that I sure wouldn't have thought would make an impact on accuracy, but I guess it's something that needs to be addressed. When my smith gets back, I'll have him re-machine it. Hopefully, all of this will get me back on track. Thanks again. [/QUOTE]
