I dropped into Prophet River to pick up my Stainless Jackson Hunter in 7mm STW yesterday. I am pleased with the quality of the rifle overall, but the dimensions of the stock are slightly different on the Model 56. The stock looks the same, but it is about 1/4" larger at the wrist. Other than that , and the stainless receiver, the rifle looks the same as my Jackson Hunters in 280AI. I had intended on shooting it tomorrow, but when I opened up my Leupold rings, to mount a scope, I discovered that one of the lower ring haves, was not drilled or tapped. Talking to two different dealers today, they have each found a few Leupold rings in the same state. Hopefully the weather is nice next week, and the replacement rings arrive, so I can shoot the rifle next weekend.

I think he said it is 7mm STW in the first line and yes pictures would be great for those who like Coopers.

Appreciate the info! If Leupold means the standard bases, I'll probably go with the Talley. I just had bad luck with the standard bases once and the windage screw got loose on me. My fault for not loctiting it but I'm just off it as a result.
Better touch base with Clay and make sure my order asks for the Talley bases.
I have used the standard Leupold windage adjustable bases on over 40 rifles, including four 7mmstw rifles, two 300RUM rifles, a 338x8mmremmag, a 300WBY, five 7mm Rem mag rifles and a 375H&H rifle, I have never used loctite on the windage screws, and I have never had one come loose, or cause any issues. However, you need a proper sized screwdriver, and you really need to torque them tight.
That is the standard Jackson Hunter stock. The Model 56 rifles supposedly use H-S Precision stocks, which have much more red in them, and they are a little thicker in the wrist than either the B&C stocks, or the wood stocks.
What's branded in the pad? Cooper, HS precision, B&C, or decelerator?
Decellerator.

^^^^indeed!
After more testing than usual, I finally settled on my hunting load for the new Cooper. I tried the 140grTTSX, but this rifle simply doesn't like it as much as my other Cooper in 7mmstw. I tried the 139gr GMX, but the groups opened up even more. I then tried the 145gr LRX, and accuracy was erratic. I did shoot a .240" group with that bullet, but the next group was nearly 1". Groups varied more than with any other bullet that I tested, but the average was around 3/4" just like the 140gr TTSX. The 140gr Accubond did better, but I prefer to use a monometal bullet, so I tried the 150gr TTSX. The 150gr TTSX proved to be the most consistent bullet in this rifle, so that is what I will be using for now. I had been using a spare target scope, but the Swarovski Z5 3.5-18x44BRH arrived, so I mounted it up, and sighted it in this morning. My goal was 1" high at 100 yards, to provide a 200 yard zero, so that the BRH reticle calibrates best for the load. I also chronographed the load at right around 3400fps. Below are this mornings groups.
I also chronographed the 140gr TTSX load in my first Cooper 7mmstw, and verified the sight in. The load produced just a hair over 3500fps, and the point of impact looks to be right where I left it last year.
