hmm this isnt right?

Over at Savageshooters they recommend removing the accuwedge from the stock as it's very hard to get torqued properly and can really throw off accuracy.

Apparently the new accustock models are shipping without it.

I removed mine but haven't had it up to the range yet to try it out.
 
You a seeing barrel harmonics at work. When developing loads pay more attention to the group size and vertical dispersion. Once you find the load your rifle likes then adjust the POI. If you work loads up at longer ranges you can see much larger POI changes with different loads.

Hmm I will try a couple groups with and without. I should be able to post them this weekend
 
Did you consider Ocham's Razor?

That you likely just aimed at the wrong target?

The POI is not going to change dramatically like that yet retain a decent group size.
Rifles and loads can be really-really frustrating at times. I have a heavy barreled rifle (Douglas supreme 22") on a Sako action, free floating .308. This rifle has been extremely accurate, I have a target posted in my office that has five rounds in .25" at 100 yards. I developed the load using 46 gr of W748, SMK 168 gr using Rem. brass and Fed 200 M primers. Well, last summer I was shooting the rifle and was getting tight 0.30"-0.35" groups and then, wham, the group moved a full 1.5" above my previous one. Still a tight group of around 0.40" but what the heck? Scope was tight, bases were also and the rifle was screwed in tight. I was at a loss. Then, I noticed that the higher group was shot with my "sighters", all components the same except I was using full length resized Win. brass! Repeated the procedure and the neck sized Rem brass shot about 1.5" lower and a bit tighter, but not much, that the Win. brass. And no, I didn't shoot at a different target! :)

FYI here's a revised torquing procedure from a Savage tech I pulled off of the Savageshooters forum for you:


The other day I had a informative conversation with Mr. Chris Bezzina (main engineer at Savage Arms) who played a key part in the development of the AccuStock. I wanted to get detailed information on torque specs for the 10 LE weapons series. There is a sequence for reassembling in the manuals but for ultimate accuracy wanted by advanced shooters the recommended sequence is as follows.

Proper Adjustment of The AccuStock
There is a specific technique for assembling the action into the AccuStock, and it needs to be strictly adhered to as follows:

1. Ensure that the recoil lug “wedge” screw is backed out to the point where the wedge has sufficient vertical movement to allow the recoil lug to seat against the bottom of the aluminum rail.

2. With the action inserted into the stock, justify the action toward the rear of the stock to allow the recoil lug on the action to be seated against the boss on the aluminum rail.

3. Tighten the forward most screw to 10 in.-lbs. to seat the action against the aluminum rail boss, then back out one-half turn.

4. Tighten the middle action screw to 10 in.-lbs.

5. Tighten the rear action screw to 10 in.-lbs.

6. Tighten the forward action screw to 10 in.-lbs

Repeat steps four through six and increase torque value in increments up to a final torque value of 40 to 45 in.-lbs.

Note: It is extremely important to tighten per the instructions above because when you are tightening the action down into the AccuStock you are spreading the aluminum side rails and evenly moving the action down onto the base of the rail, ensuring positive engagement.

Like I said before, Savage has removed the wedge from their new rifles so I'm eager to see your results.

Thanks for the info, its pouring outside right now, hopefully I will be able to test that out soon.
