With the development of the wsm's being as successful as they are. I'm curious if Winchester is in the development stages of a 338 on the same case.

My 300 can throw 200gr at a very affective velocity, around 2800fps. I don't see any reason a 338wsm couldn't throw 250grs at 2500 - 2600fps, possibly more with a 24 inch barrel and no belt to deal with. There wouldn't be any advantage over any thing that already exists, but the rifle could be built an inch or three shorter, lighter and handier. Recoil could be some thing that would have to be dealt with. Ouch. It would, most definitely, not be an every day shooter.

These long range target shooters are drooling on the wsm's cases wanting the development of a .264 size on the same case.

Fuzzybear, I have been waiting for the .264 WSM and the .338 WSM as well. I was very disappointed in the fact that the .25 is a WSSM, not a WSM.

Yea, I think the 338 on the wsm case would be a good 200 - 250 yd cartridge for anything you would hunt on this continent.

If a hunter had a 270wsm, a 300wsm for general hunts. A 338wsm for heavy game and a light weight 264 for those extreme mountain hunts. They'd have all the bases covered.

I chose the 300wsm for my general hunting. With the 270wsm I had a special rifle built. The performance of the round seemed perfect for a long barreled long range shooter. I would like to see the development of and add a 338wsm in a rifle with a 22" barrel and a ready to hunt weight of 8 to 9 lbs. I would also like to add a 264wsm with a 22" barrel and a ready to hunt weight of 6 1/2 - 7 lbs.

What I would do is use the 264 and the 300wsm's for most of my hunting. In the 264wsm I would load 120gr and 140gr. In the 300wsm I would load 165gr and 180gr. In the 338wsm, 225gr and 250gr. The lighter bullet of each caliber would have a design with a high BC. The heavier of each caliber would have a heavier construction.

My 270wsm is set up to shoot 110gr and 130gr for extemely long range varminting and 130gr and 140gr for those long range high dessert, open prairie, deer and antelope hunts.

Yep, if a guy had those four rounds he would be set for any game he wanted to chase after, in any terrain, on this continent.

I'd have to go with the 7mm WSM for right now. It would be a happy medium between the 270 and 300 WSM. Would do the work of both, and just have one gun. I would still want a .264 WSM.
If I were to go bear (brown) hunting, I'd get Browning to chamber a BLR in .338 WSM, which they probably will when Winchester develops it. Can't think of a much better bear gun. Light and fast-handling. Accurate enough for longer shots, but very handy at close range, and it would certainly be potent.

The 338wsm would be an effective round in the BLR. Possibly, the best combination for large / dangerous game with that round. Loaded with Bear Claws it would most definitely be a stopper.

Ahh, I don't see how it's any better than a .338 or a 340. IMO, that is.

It's better in the respect as a dangerous game rifle, you have a much shorter, easier-pointing, and faster-cycling rifle, as opposed to the other rifles that fire the non-WSM rounds. Although I believe the BAR comes in .338 Mag. That's a pretty fast cycler! But most of those are long bolt guns. The discussion was the combo of the short little lever and the potent round. As far as the round itself, I would imagine it would be very similiar in performance to the .338 Win Mag. It's the action, not the power, which was the intent of the WSMs all along. Here's where it makes perfect sense.

Yeah, well hey, save that for non-dangerous game. Besides, the last thing I want is a sharp-shouldered, extra-fat case that may fail to feed properly. Besides, think of it another way. Think about the bullets you shoot out of a 338 magnum. Hell think about what 338 magnums are frequently used for. When I'm hunting something that could rip me apart, the last thing I care about on this earth is what length the action on my rifle is. eye roll

I've been doing some figures for the wsm cases in assorted different calibers.
What I've come up with is the wsm in .264, .300, .338, .375 should or do throw a same weight / diameter bullet approximately 100 fps slower than the same caliber belted mag. 264wm, 300wm, 338wm, 375H&H.

I've heard and read about the restriction of the heavy for caliber bullets in the wsm. My 300wsm loaded with 200gr Accubonds gets 2800+ fps from a 22" barrel. A 300wm will push 3000 fps with a 24" barrel.
For all practical purposes. A 250gr .338 bullet should leave a 24" barreled 338wsm at 2750 fps. That would be 100 fps shy of a 338wm with the same length barrel.
A 264wsm should and probably will push a 140gr at 3000 fps through a 24" barrel. I'd like to see Ruger build a light weight single shot with a 26" barrel in this caliber when it's developed.
From the stats I've been working up. Winchester has come up with the best idea since sliced bread with these wsm's. I hope they keep developing more calibers based on this case. Maybe someday these heavy, cumbersome belted mags will blow away with the dust. Remington has already developed better, comparable rounds than the belted wonders on the same case as the wsm's and only 3/4" longer than the wsm.
Long Action - RUM, case length 2.85"
Short Action - WSM, case length 2.10"
Same case approximately 20grs difference in capacity.
Say goodbye to the belted mags. There end is drawing near.

I can picture it now. The shelves and racks filled with,
264wsm's
270wsm's
7mm wsm's
300wsm's
338wsm's
375wsm's
and no belted mags. That would be a great day for the hunter, shooter and reloader. Especially the reloader. No more worthless belts.

I have a friend that just finished building himself a bolt actioned 45-70 that can throw the same weight bullet 100 fps shy of what the 458wm is capable of. Another example of the worthless belted cases. The 45-70 just happens to be a short action round also. Amazing, isn't it. A case length of 2.1 inch and is capable of keeping up with those over rated belted wonders.

Well, that or the short mags will disappear once the novelty of their short cases wears off. I guess field performance doesn't matter anymore. eye roll

And how exactly is a belted case worthless? As of this moment, right now, a belted magnum outperforms it's standard counterpart(s).

Remington's SAUM line do not outperform regular magnums, I've done enough range testing to know this, and they are not more accurate from the bench, and neither are the WSMs. Smoke in the mirrors, I might say.

To summarize the above: Short actions don't make you a better hunter, and neither do short cartridges. Right now, everything they can do, the normal mags can do as well, or better, so wake up, and face what they call reality.
