Will you still benefit from bedding the accustock or has it come such a long way that doing so wouldnt improve the accuracy? I have searched a bit couldnt find anything on the matter..so here I am. :P

No

would a new corvette z06 benifet from a msd 6al box?

Bedding a riflestock is so 1950,s

My Sendero SF benefited from bedding. :confused:

Does your sendero have an aluminum chassis that mechanically mates to the underside of the action and is bonded Into the stock itself. Or as with remingtons idea of a accuracy stock simply a piece of fiberglass with a pair of aluminum pillars

If you would have looked at the Savage Accustock you would have noticed that the stock uses a full length aluminum bedding block, a wedge system to draw/clamp the recoil lug and an aluminum channel that 'grips' the sides of the receiver so as to align the receiver longitudinally within the stock....

Where would you even 'bed' this bugger...?

The receiver sets in/on the aluminum bedding block, the barrel channel is free floated, the recoil lug is pinched and drawn to the rear of the rifle stock....

It don't get much better than that...

I agree; I would be very careful in bedding this. It is engineered to tighten down in cerain ways; if you did something to restrict certain movements, you could end up jacking it all up...

I've heard of "skim" bedding even when aluminum V bed blocks are integrated but the Accustock takes the bedding block idea a litte further and I'm not sure it would benefit.

Thank you all for your insight.. looks like theres no known exploits in the accustock. As with everything that comes from savage nowadays.. flawless at a low price.

Don't get me wrong the Savage rifle is a lot for the money (and I like mine lots) and they do deliver some serious accuracy on the cheap but "flawless" they aren't!

If bedding a rifle stock is so 1950's, I guess you can just call me Elvis. Bedding changed my CZ-550 .30-06 from a scattergun into a sub-MOA rifle.

The Sendero does have an aluminum subframe. It is not "simply a piece of fiberglass with a pair of aluminum pillars". It is not near the same system as the accustock but it is way better than just pillars. It would be interesting to see some real world statistics of improved accuracy with the accustock vs. a good composite bedded or not.

I agree with the already given advice not to bed an accustock.

The stocks with aluminum bedding blocks are one way to get rifle mated to the stock and to get it to shoot well. The glass bedded stocks, whether wood or fiberglass is another acceptable way to do it. Both work if done correctly and both have their advantages. The aluminum bedded stocks are less expensive. The stocks without aluminum blocks can be more trim and lighter.

The September issue of G&A has an accustock review. Groups averaged .300" smaller with the Accustock.:)

I haven't seen that yet. .300" smaller than what? I'm sure they're an improvement over the other Savage method if that's what they compared. I'd like to see a properly bedded composite vs. the accustock.

The standard stock.

Do you really want to see a higher quality bedded synthetic (non tupperware) stock with a bunch of labor and $ put into it vs the savage factory piece. Bear in mind as well that bedding is only as good as the person doing it. Take the new Savage BAS, Shooting times tested this rifle and in the process averaged well under 1/2MOA for five 5 shot strings with a particular loading. Why would you even think about bedding a rifle shooting that good

I love savage for these innovations. They're literally doing their best to force the precision riflesmith find another day job. I'm starting to call them the ar of bolt actions because of this modularity. First easy bbl changes with no more than a wrench and now stocks that surpass the best bedding jobs with a turn of an allen wrench.

There are thousands of guns in the U.S. that are bedded that will shoot 1/2". A quality bedding job is a thing of beauty and fits so tight it's work to de stock it. I have a Stolle Panda 6ppc with a Krieger barrel built by Don Nielson. The inletting and bedding are so precise it's a shame they cannot be seen by the layman.

It comes as no surprise the accustock is an improvement over Savage's conventional inletting methods. I consider a Remington Sendero with the aluminum bedding block a lot better than Savage's conventional inletting as well.

I see you're not a fan of Acraglass. Most good smiths use products much better like Devcon or Steelbed which are much stronger than the Kevlar/Fiberglass stocks themselves. I'll tip my hat to Savage for thinking outside the box and trying to invent a better mousetrap. Personally I believe there is no better mousetrap than a properly bedded rifle in a ridgid stock.

But not "outta the box" that's the key point.

I respectfully disagree. In my opinion properly machined metal to metal surfaces beat layers of epoxy or fiberglass every time no matter how skillfully applied.

The factor that's brought these changes about are the high degree of precision and speed modern machine tools provide. Years ago bedding was the only way to obtain the stock to action tolerances as tight. Today a CNC machine cranks em out by the dozen

It would be interesting to put blue layout dye on the action and assemble the rifle. De stock it and see how "properly machined" the accustock is. A properly bedded rifle has 100%contact. I'd be very interested to know how much contact the bearing surfaces of the accustock have. It may surprise me but I'd want to see it.

I don't doubt the accustock is an improvement over many other factory methods. My Sako uses a steel plate screwed into the stock. A square hole in that plate accepts the square recoil lug. Kinda the same concept on a different level. I think the TC Icon has an aluminum subframe but haven't seen how they mate receiver to stock.

I would be very surprised if even a professionally bedded stock went over 80%. Even so metal to metal tight fits on even a couple small well controlled points will provide ample bedding. it's not about % of contact afterall its about secure stock to action mounting. Typically on aluminum chassis systems the action screws are set to a much higher torque than with traditional bedding allowing for this.

Just look at how many of the worlds long range professional grade rifle systems have gone to a chassis style stock system in recent years

I can't argue that. We can certainly do more with CNC type machining than ever before. Time will tell.

Is the accustock still a blow molded hollow stock?

that is a beautiful pic, by the way.
Plus if I understand right, and i think I do, when you tighten this up, the lug is also, tightened, squeezed and pushed backwards, while the rear of this aluminum house, is pushed against the back of the receiver, and pushes it forward; thereby you get it not only tightened all downward against the frame, but also squeezed together, front and back , towards each other.
Sounds super stable to me, but I am no gunsmith, tell me I am wrong here, and
I will agree...

Bedding changed my CZ-550 .30-06 from a scattergun into a sub-MOA rifle

Scattergun.. CZ's have always been accurate before a bedding job no? :uhoh:

JimmAR, I have always found CZ's to be accurate, but this one wasn't. A very good friend did the bedding job for me for $25.00. I had the same problem with a Ruger 77 in .243. It just wouldn't shoot. I had the barrel free floated, put in a Timney trigger, and tried just about every hand load in the book. It still wouldn't shoot. Had it bedded by my friend and it shot sub-MOA. As to why I didn't buy a Savage, their new stock system was still in the future by several years. My CZ now shoots about as good as any other .30-06 I've seen. YMMV.

Not exactly 'blow molded' but the butt portion of the stock is a hollow cavity filled with styrofoam.
