Bedding a New Winchester Model 70 Extreme Weather SS

[Doc7]

Hello all,

I will be getting this rifle soon. It is sold in a Bell & Carlson stock with aluminum bedding block. From various reviews online from years past, it may or may not be "skim bedded" with hot glue.

NO 6. All stocks need pillars, even stocks with bedding blocks

This link has some points in it that make a lot of sense to me, particularly:

"Both the H-S Precision, and the Bell & Carlson Medalist stocks have an aluminum bedding block with a machined bedding surface. Also, we know that our rifles receiver is a machined part. Since these two parts are both machined, it seems logical that when we assemble these two items, we should only have to install the guard screws, tighten them, and be done with it. This seems especially true with a Remington, where you are placing a round receiver against a "V Block".

But wait, is your action straight? Most are not! The heat treat process occurs AFTER the reciever is fully machined.
During this heat treat process, each receiver will warp in its own small, but unique way. This warpage, by itself, prevents a stress free fit of the receiver to the bedding block.

Accu-Risers and epoxy are not just the easiest way to deal with this warpage, but the most accurate way as well."

So my questions are as follows:

a) If doing this with his accuriser pillars, do I need to remove the bedding the rifle comes with or do I bed simply on top of it?

b) He coats the areas to be bedded with compound and then inserts the barreled action into the stock and tightens action screws to 10 in-lbs. I am imagining that some bedding compound rides on top of the screws all the way into the bedded action as he does this. Does the screw still screw back out at the end or is there a special procedure? I am also imagining that that compound riding on top of the screw will never move from that 10 in-lb location where it stops so how does the screw tighten further after it is hardened up there?

Shoot it first. If its stacking them right in there whats the point. Secondly I have had an HS orecision stock andcwas not impressed with the bedding. Neither was Doug Shilen when I sent the rifle to him. I would recommend glass bedding if you want an increase in accuracy.

You best use release agent on all the metal and the screws or you will never get the rifle apart again after the bedding compound cures.

Without release agent on everything, it would be permanently glued together into one unit.

What is the best way to get release agent into the interior threads of the receiver where the screws go in?

medicine dropper?

You can use a pipe cleaner to get down in the threads.
Be sure and coat the screws and guard inside & out too.

I used to use modeling clay to stop up other pin holes, slots, etc.

You want no opening were bedding compound can get a death grip on the metal anywhere.

I would think twice about buying a rifle when I have convinced myself that it wasn't going to shoot decently.

I have 2 model 70s that shoot great with no alterations except for lightening up the trigger pull. Certainly try it first!!!

If it;s a newer Model 70 it has a bedding block (As noted) in the stock already and the barrel is free floated.

Shoot it first.

If it ain't broke, don't fix it.

I recommend coating all metal parts that will contact the epoxy with carnuba wax. and waiting until the bedding compound becomes "tacky" not liquid. still soft enough to form to the rifle yet set up enough so that it will not stick to your finger when you touch it. I let the wax dry prior to bedding the action.

Just out of curiosity did you read the link in the OP about aluminum bedding block systems which are machined by a CNC to match nearly but not precisely to the heat treated receiver?

Thanks for all the opinions in this thread folks. I will shoot the rifle without doing anything first but as a tinkerer and knowing that bedding may squeeze extra accuracy and consistency out of it I may still do it in the future.
