Home Forums Hunting & Shooting Hunting Rifles New Winchester 70 Extreme Weather SS .308

Okay, so I took the new baby to the range for its first play session this weekend. I couldn't be happier. But before I share the results, let me share a few specs. After mounting the Leupold 2.5-8x scope, the rifle finished out at 7.6 pounds, which I think is perfectly acceptable for a do-anything rifle such as this. Also, it balances beautifully. The balance point is 5 7/8" in front of the deepest part of the trigger.

So I tested four factory .308 loads over two days:
1) Hornady American Whitetail (150 gr. Hornady InterLock)
2) Federal Premium (150 gr. Nosler Ballistic Tip)
3) Federal Premium (150 gr. Nosler Partition)
4) Nosler Trophy Grade (165 gr. Nosler AccuBond)

Below are a few groups (and photos):
Hornady 150 gr. InterLock = 5/8"
Federal 150 gr. Ballistic Tip = 3/8" (by far the best group all weekend)
Federal 150 gr. Partition = .60"
Nosler 165 gr. AccuBond = .98"

The combined average of all groups shot this weekend with all loads at 100 yards is 1.18"






All in all, this rifle appears to be the most accurate rifle I've ever owned, which makes me very, VERY happy! ;-)

Excellent! I'm glad she's a shooter....congrats!......Hb

By the way, I ran all the loads through my chronograph, just to see what I was getting out of the 22-inch barrel. Temp was about 75 degrees, 80% humidity, and we were at about 1100 feet elevation.

Hornady American Whitetail 150 gr. InterLock = 2798 fps avg.
Federal Premium 150 gr. Nosler Ballistic Tip = 2829 fps avg.
Federal Premium 150 gr. Nosler Partition = 2895 fps avg.
Nosler Trophy Grade 165 gr. AccuBond = 2641 fps avg.

I don't think my images showed up in the post above and I have no idea why. Here's the link to my image gallery and you can see the groups there.

Good shootin bump.....

Oh yes, some very good shooting......Hb

Go buy about 15 boxes of that 150 Partition load and dont look back. Best factory rifle going IMO, miss the 30-06 I had. If I were to purchase another it would be a 7-08.

Outstanding, wish my pre 64 FW 308's would do that. They are a little fussier with loads.

Good deal FairChase! You got a keeper for sure. Congrats-

Thanks for posting these pics for me, 16bore! Don't know what I did wrong but I couldn't get them to show up no matter what I tried. Anyway, I appreciate the help!

Yeah, I was thinking the same thing. And about 15 boxes of the American Whitetail load. Of course I'll do some handloading for it soon too, and it'll be interesting to see if I can do better with the AccuBonds and 165 gr. Partitions. But I could take it hunting tomorrow without a concern in the world. Now all I need is something brown and fuzzy to point it at. ;-)

Go to your gallery, hover over the thumbnail and click "open in new tab". Copy the URL then go to the "full editor" mode and select the picture icon, and paste it in the box. Probably and easier way somehow, but it works.


Don't know that I'd bother touching the press with factory groups like that!

16bore . . . Well, I thought that's what I'd done before, but I just went back and edited my earlier post doing what you said and voila! It now has images. Must not have been holding my mouth right the first time. :-)

Thanks for the help!

Nice rifle and some really nice shooting. I had one of the early SC Extreme Weather M70’s in 308 that was a shooter too, but for reasons I don’t remember, I let it get away. Been sorry for a long time now.

My 7mm-08 would not shoot under an inch even after two trips to Hill Country Rifles. It resides in someone elses safe now, too bad I love the rifle.

I have a new Featherweight 270win coming tomorrow and I just hope it shoots like some of the rifles above....

Nice rifles and nice shooting! I put a new 270WSM Model 70 Sporter in the mail yesterday. Going to order a steel floorplate for it, rather than the alloy it is coming with.

Where are you getting the steel floor plate? I want to do the same

Thanks

my south carolina version, also in 308, shot both 150gr federal fusion and 150gr corelokts so well i've never tried another factory load for deer. for elk i just bought a couple boxes of federal premium 180gr partitions. i don't remember how they grouped, but one shot killed my elk last year at 266 yards. like the op, no need to reload for my ew. wish all factory rifles were as good with as little work. ymmv.

A private source that I can't repeat, but if you look on eBay, once and awhile they list Winchester new & used parts. The alloy is nice, but steel is king.
