:grin: Will a 300 Win Mag fit in a 98 Mauser action? I know that I will have to; open up the bolt face, and the feed lips. that has already been done as the gun is chambered for 358 Norma Mag.
I was wondering about the oal length?

Thanks

It should work fine.

The 300 winchesterMag is the original short magnum. It was developed to allow 300 H&H ballistics in a standard length magazine. The rebarrel should be fairly easy!! Good luck! The 300 mag clan are some of my favorite cartridges..

Actually the 275 H&H Mag was the original short mag. Introduced in 1911 or 12, was the 375 H&H shortened to 2.5" and necked down to .287". Original ballistics were identical to today's factory loads of the 7mm Rem Mag.

You are right I suppose but of course you knew I was referring to the line of 'short magnum' rounds introduced by Winchester.. The H&H round never found favor in this country.. although the Remington version surely has. The rounds I was referring to were the 300 WinMag, the 264 WinMag, and the 458 WinMag.

I can understand that. By the way, the 458 WM was introduced first, then the 338 WM and 264 were introduced in '58, and the 300 last (1963, I think).

I think you will find that the .308 Norma was the first and this is what gave Winchester the idea for the 300 Win mag.

The Norma design was not produced by an american maker and never sold well. It's main claim to fame was a slightly longer neck. This supposedly aided in bullet alignment. The 300 WinMag has all the control needed to produce fine accuracy and all the power needed for most 30 caliber applications.

Gunnut, do I get the idea that you are not a .308 Norma fan? From what you said about the power of the .300 Win mag I would guess you would not care for the .300 Ultra either. I sort of get the idea that if you want 4000+ fpe then you, like me would like a bigger and heavier bullet then you can get in a 30 cal. I like the .308 Norma because I can seat the bullets .010 from the lands and still get it into a standard length mag where with the .300 Win this can be a problem. arguing the difference between these two cartridges is on a par with arguing about which is best the 30-30 or the 32 Special, they are that close. The other thing I like about the Norma is that it is a bit different and not so common.
One thing I find interesting is that if you look in Ackley's book you will find all sorts of "short or standard" length mags that came out well before any of the companies including Norma picked up on the idea. It seems the factories let the wildcatters create a market, or test the market any way before they jump in. Case in point the 7mm Mashburn, now known as the 7mm Rem Mag, or the .416 Barnes supreme which is now the .416 Rem mag. What are your thoughts on all this?

I absolutely agree, the companies were much more attentive to the marketplace than they are now. Today I feel they try to push the market to create another market niche. The WSSM and other short rounds don't have any majic properties. Had a gentleman tell me he was certain him 300 wssm or whatever generated more velcoity with the same pressure and generated less recoil.. Strange, Winchester seems to have altered the laws of physics!!! Roy Weatherby made similar claims for the double venturie shoulder... It also was happy hogwash. Reloading tests seem to bear out velocity and case capacity and pressure are in sync between the supershort mags and the former short mags, the 300 win , etc... The problem with bullet seating is easiest to fix by throating comensurate with the OAL possible in the action being used. Long throats are a fixable problem.. I built my 300 Mag on a Winchester made Enfield action. To best utilize all the case capacity I use 200 grain spitzers (Nosler Partitions) and a 26 inch barrel.. It was throated for the 200 Speer(the bullet I started with) although I was forced to switch when one of these HotCore bullets exploded on the ribcage of a largish whitetail buck. I have nothing against the 308 Norma, just no reason to go to the trouble,, The 300 Winchester properly chambered will do more and will also fit into standard length actions. I believe the ultra's are baloney... If I needed more horsepower I'd likely go to larger bullets(you are right).. I kinda like the 338 WinMag but have a problem finding something around here large enough to warrant that much killing.. I usually use a 7mm Mag or the 300 win when serious but enjoy the 6.5x55 and have used the 243 extensively on deer. I've killed 2 moose, both with 30-06 and 180 nosler partitions.. I am experimenting with a 38-55 levergun and contemplating a 444 or 45-70, just for kicks.. I've a 25-06 (Ruger No.1) and a 270 (Rem m721/douglas barrel) in the works. Just can't seem to find the time for my own when the customers are waiting.. My favorite centerfire is (by rounds fired) is likely a 222 although the 22 Hornet is approaching equality rapidly.. As to wildcatters creating many of the great cartridges you are certainly right. Gebby, Page, Ackley etc. can claim a great many fine rounds..

The .308 Norma beats the 300 win hands down!!!! Right? back to the 30-30 vs 32 Special again. I would stay away from the .444 as you are limited to pistol bullets for the most part and many of my customers have had problems with this. On the other hand the 45-70 is another story, more case capacity and lots of bullets available for everything from deer to Elephants. (You knew I would put that in here.)

On the 308 Norma vs the 300 win mag I'll agree to disagree. The great thing both of us can have what we want!! My buddy uses the 300 grain Hornaday XTP with good effect. He's shot deer lengthwise and not recovered a bullet. If I were planning on something bigger I'd likely use the Nosler Partition for this caliber.. or a tempered hard cast lead bullet.. or most likely that 338 I spoke of before.. I've killed 2 moose with the 30-06 and 180 Partitions. Put bullets in one corner and out the other.. nice exit wound! No recovered bullets. I've always kinda lusted after a 45-70 but heavier slugs are likely the best for this beast. Unless we fall back to the 300 grain loads, of course then we'd just as well use the 444 which is more at home with the 300 grainers.. Choices, choices!! Actually with the arthritis acting up more and more, I'll likely stick with the 6.5x55 or perhaps a 7mmMag for the deer season.. It's been grat but I believe we've hijack this thread enough.. Have a great day Judson!!

You have arthritis too? I have R.A. and am on Remicade every six weeks. The 6.5 X55 is a great cartridge!

Was on Vioxx now am using ibuprofen and naprosen(sp.). Doesn't help a lot but lets keep going, after a fashion.. Some days the swelling is debilitating.. They tested for RA but didn't find whatever it was they were looking for.. Hands swell really bad, especially after a day of checkering or even worse, relief carving. I love to build Kentucky rifles. even inletting can get painful... Have a good day..
