HOT DAMN.

Ya know if this is really not a dream I get the best of both worlds..

1) 06 brass

2) And John B.'s 9.3 bullet

In the same case none the less.

an overly exuberant Spot

With the increasing availability of brass and bullets, and decades long acceptance of the 9.3 X 62, I have to wonder what the point of the .370 sako might be.

The 9.3 X 62 is real close to the Brown Whelen, necked up.

.370? Not a bad idea, but it's already here.

Just the 9.3x66 renamed for the American market.

Nothing new here.

Sako has said they were looking to get the largest possible capacity in the '06 cartridge case for their 9.3X66, call it the .370 Mag for North American marketing.

jim

even thou its a 9.3 whelen its a very useful caliber and if I didn,t own a couple 35 whelens and 375 H&H rifles Id probably grab one for ELK hunting the timber as Id bet it is a very effective stopper in the 0-300 yard range Ive normally killed ELK in

Is the 9.3x66 Sako/370 Sako Mag. truly based on the 30-06 case? I know they share some dimensions but does that mean you can use '-06 brass to form the 370? Maybe 30-06 basic? I had heard that the 9.3/370 Sako has a beefed up web area and was designed so the hybrid powders that VihtaVuori was developing - N500 series - could be used.

The 30-06 is a 7.62x63.

Maybe I am missing something here, but isn't the 9.3X62 case very close to the 30-06 case in dimensions and capacity?

If so, why doesn't Sako just offer their fine rifles in the USA chambered to 9.3X62?

??

One more reason for me to stick with the 338 Win. Mag or 375 H&H.....

AD

Yes it is. In fact I necked up an '06 case to 9.3 just to see if it would work. Fired in my 9.3X62 just fine. There is no point in doing this as there is plenty of good brass out there. But in a pinch it works.

Thanks Outcast,
I have a 9.3X62 which I use Lapua brass for; I am very happy with the brass.
I guess the point I was trying to make(I did not make it very clear) was that why would Sako introduce a new caliber that is so very similar to the 9.3X62?
Why not just market the 9.3X62 in the USA instead?

No, the new 9.3x66 Sako / .370 Sako Magnum cartridge is in-between the existing 9.3x62 and 9.3x64 Brenneke but not by much. It is more like an updated version of the 9.3x64 Brenneke.

Here is a ballistic comparison of the 9.3x66 Sako, 9.3x62, 9.3x64 Brenneke, and the 35 Whelen.

The Sako will cost about $1,500 and a box of factory ammo will cost about $85.
And from the looks of it the .370 Sako Magnum does not have much of a shoulder to headspace on.
So, I don�t think I�ll be buying one. Besides I have a CZ 550 FS in 9.3x62 on order.

But of course I have been wrong before.

Put me down for wanting one.

OK I GUESS some of you guy's missed the excerpt from Federals web page that I had in my first post.

http://www.federalcartridge.com/default.asp?pg=46

Look at the 370 sako infor and you'll see they say it's 30-06 brass.

So can any of the cartridge guy's validate that?

Spot

I believe that the Whelen numbers can be cranked up some......
I'm not stating that someone should ignore the loading manuals. Just stating that it seems most factory loadings and the manuals seem geared towards the weaker/older rifles.
T

I would like one also.
I wonder what pressure they are loading to?

USA marketing????? I believe the word magnum may still be the "Buzz" word for some.

I thought Mule deer would confirm the case head size thing.

Spot

Its a 2.6 " 06 case, more like a 35 gibbs, a 250 at 2750fps. if the one I ordered ever shows up mabe in a month i will give a full report on it. sako doesn't do the whelen so this is next best.
