John I more or less agree with a thru-bolt attachment as I’m really not interested in re-design or mods of this type. If the g uns need this to shoot, and I’m not sure this is the case,  then I’d get rid of it. I want to get to shooting and not rebuilding or hot rodding the gun. 

Today I removed about .005” from the after end of the forearm per Boat’s suggestion. It was not square to the face of the receiver for one reason or another and making hard contact on one side. It’s got .010” now. Then I started looking into barrel lockup or movement but I can’t see or feel anything so my gut says it’s probably okay otherwise I’d have to jig up hold the receiver and indicate it. Same with the butt stock but that will be easier for me I think in the wood shop in the Emmert vise. I do worry about too much squeeze on the action though. Easier methods I’m all ears. 

So I chrono’d eight shots today. 300 gr breach seated tapered bullet over 18.0 gr of IMR 4227 with Fed 210M primers. From what I found I’m getting good results. Nine shots avg 1301 fps, Hi was 1306 and Low 1298with ES @ 8fps . I may be wrong but these seem like decent numbers so I’m sort of doubtful that there could be issues with ignition, at least in this small test sample. Pretty sure ignition problems show up in velocity spread caused by faulty, delayed or erratic primer performance from light hits.  Creighton Audette did a pretty thorough study of primer performance years ago in Precision Shooting. As it stands I’m going to try and wring this rifle and myself out until I find the answer

Thanks all

The triggers not working Joe and Jack Hughes could probably explain it better than I can he has one of those problematic rifles. The other issue is there is very little contact to the back of the action there are just two little tenons actually touching the back. From the back of the action to just about the back of the tang all of the wood in between has been removed. All that I have worked on when looking straight down from the top I am able to see daylight between the tangs and the stock and there is little if any lateral support. When tightining the through bolt it will also start to flex the bottom tang and their is a fine line of getting the triggers to work or not. This also typically occurs prior to the stock being tight enough.
