I have a ss fluted bull barrel for a mauser action. it is short chambered for .300 win mag but i am looking at having it chambered in .300 ultra mag. anybodies opinion? thx guys

.300 Winny takes in the area of 78 grains of powder, .300 Ultra mag takes in the area of 90 grains of powder. The Ultra will beat the Winny by 100 to 150 fps on all bullet sizes. You pick your poison, it is your shoulder. Good shooting.

Here's the real set of problems you're up against. Rechambering that barrel is the very least of it:

If the barrel is setup for a Mauser, you'll have to have a Mauser action properly reworked to go with the Ultra-Mag. That means you'll have to have it completely bluepinted, the loading port opened-up, the bolt face and extractor reworked, the feed-rails opened and the feed-ramp reworked, plus you'll need a completely new magazine box and follower, the bolt-stop altered, a new bolt handle and a new safety system installed that'll work with a scope, a new trigger, new bottommetal (integral with the new box), plus you'll need to have the action properly rehardened or risk lug setback.

You'd face the same stuff if you left it 300 Win. Mag., but the 300 Win. Mag. is a lot more workable with a Mauser action than the 300 RUM is. But at least you could find a beater factory-original Browning Safari LE in 7mm Mag., 300 Win., or 338 Win. and use that action with that barrel at minimal expense.

But if you use a surplus Mauser or go RUM, all of a sudden your barrel and bargain Mauser action is anything but a bargain -- it's thousands of dollars beyond being a bargain.

The best thing to do is to forget that barrel and buy a factory rifle in 300 RUM if you must have a RUM. If it doesn't shoot to your liking, get it rebarreled at that point with a different tube. This is the cheapest and best way to go, because if that rifle doesn't shoot, at least all you need is a new barrel -- the action and everything else will be just fine as it is...........

Good advice by Allen.

If the barrel is long enough it can be rethreaded for another action as it's a bull contour. Somehow old Mausers and bull barrels for high intensity cartridges don't seem to go together for me.

Gun parts like that can be a burden. Put it away til the right action comes along. It would make a nice 1000 yd gun in a single shot 300 WSM!

price a box of ammo or brass for both that should help answer your question

Personally, I've never seen the purpose of the Ultra Mag type of cartridges.

If a "standard" 300 Mag can't handle it, I'm moving up to a 338, etc.

They just seem like way too much of a good thing, so to speak.

By the time you do all of the work necessary, you have spent a bundle.

You're putting up with a whole lot more expense, recoil, etc for what I consider a non-meaningful gain.

And, if resale is ever a consideration, I'm betting you'll move a 300 Win Mag a whole lot faster than an Ultra Mag.

Charles daly makes un-barrled large ring mauser actions all ready to go. thy run about 300-400 dollars. it seems to me that one of those would be my best bet..but I dont know. This barrel is driving me nuts. It is just sitting in my closet and I want to do somthing with it. it is a nice barrel. I am torn between making it a long ranger or just a damn big deer rifle, ie synthetic stock 3-9 x 40mm. I like some of Richards micro fit custom varmint stocks, but like I said I dont know what the hell I want out of this barrel. I appreciate your guys input. keep it comming- moe

Actually if you are a handloader,the price of brass is not that much of a factor.Bulk brass is simularly priced from my suppliers and since the cases are used several times,the cost difference becomes insignificant.

Now that is something...

Two posts by Allen and Savage and I agree with both. Vent: if you want a long range rifle, skip the Mauser, esp with a heavy barrel.

Where have all of the "you can load down a bigger case" guys gone?? I guess that only works for the chamberings that THEY prefer!!!

While most of what Allen has said about getting that bigger case to feed is true, dispite popular mantras, people have been known to accomplish this sort of thing without requiring a second mortgage on their house. A good dose of reading, some special tools and a handy person behind them can accomplish quite a lot.

Im sure if he were to examine some of my rifles Mr. Day would turn up his nose and sneer, but I dont care about that, because I know that they work quite well and suit my purposes just fine.

With that being said, I certianly wouldnt advise going to an Ultra, but I wouldnt discourage a guy from getting what he really wants either. Make up your mind what you want and then ask for help getting it done. Building a custom rifle isnt cheap, but it can be done by anyone in whatever flavor they like. Go for it!

300 Ultra mag is the biggest hog ever to come out it uses over 90 grs of powder just to get 100 to 150fps more than a 300 win mag or 308 norma mag.
I had one I was so disgusted I had a 404 made on the action. Go with a 300 Win mag or 308 norma mag and save yourself the headache. I have a wildcat that will out shoot the 300 Ultra mag with a 200gr bullet and using 78 grs of H-4831.

To me the biggest hog to come out is the 30-378.Well over 100gr of powder to gain 100fps over the 300ultramag.

AZwriter,
please indilge me further on the mauser / heavy barrel not being long range.thx

stubblejumper,
more on the 308 norma mag? heard of it but never seen or used. thx alot guys

OK I second that the 300Rem Ultra is second.

308 Norma mag is what some people say the 300 win mag should of been. 308 N.M is an excellent round but if you want to get factory ammo almost anywhere then I would go with the 300 Win mag if you hanload I go with the 308 Norma mag. But I would definatley take the 300 Ultra off the list.

223 VV,

The 308 Norma is an excellent round that is just a tad bit shorter than the 300 win mag. Actually there really isnt enough discernable difference between the two to really matter IMO. The Norma is more popular in Europe than the States. Its US equivalent is the 30/338 which is a wildcat.

I would suggest that you go with the 300 WM. It is by far the most popular of its ilk in the US and as such the brass and dies as well as over the counter ammo is readily available. You should research your choices thouroghly before deciding on a corse of action. Im not sure but Im guessing that building an ultra on a M-98 action would make your bullet selection/seating depth quite limited because of the length of the action vs the case length. Even after magazine box alterations.

I've found the difference to be more like 200+ fps, more with heavier bullets. That's from the same rifle with the same barrel. Or looking at another way, bullets 20-30 grains heavier at the same velocity.

In a mauser action the the only decent choice between the two is the win mag. The Ultra Mags are too much work to get to work in a Mauser action to be practical.
If you are wanting a little more velocity than a 300 Win Mag and a non belted case, maybe you should consider a 300 Dakota. It will work it a std length action better than an Ultra though it will require bolt face and rail work...............DJ

If you want tp play with the .300 RUM which I have decided I wanted to as well, I would think that a Rem 700 might be the easiest path to follow and there would be some heavy barrelled .300 RUMS floating around to boot. I really feel this round is at it's best for long range varminting of bigger game where a little flatter shooting and a little more punch at longer range is what is wanted. To get that benifit I feel you need a varmint gun configuration.

I would like to reccomend a Rem 700 .300 RUM PSS

I TALKED TO A FELLOW AT DAKOTA ARMS AND HE SAID THAT THEY HAVE ACTIONS THAT WILL MATE RIGHT TO THE BARREL WITH MINIMAL WORK. IE HEAD SPACING. THE ACTION IN SS WAS AROUND $450 I THINK. ASIDE FROM THE DAKTA ACTIONS HAS ANY ONE DEALT WITH THE CHRLES DALY MAUSER ACTIONS?

This is excellent advice and quite practical from an economic standpoint. I see nothing to say except praise for it.

Hey Ventilator:

You close to Pella? Call Gordy Gritters and talk to him if you want an accuracy rifle. He has built several for me.

the 98 action is not stiff (bends esp with a heavy barrel), the recoil lug is small, the lock time is slow (I think Jim Carmichel compared it to a bank vault door closing).

After reading all this I am pretty sure i am going to stick with the winny, but correct me if I am wrong...I thaught the m98 was a good action? I have never owned one. My buddy has a MItchell Mauser in 8mm and it shoots great...thx again for the input-moe

I went to the hardware store today,,,Not tru valu,,not ace,,,,I mean the last true old time hard core "hardware" store I know in existance,,,Picked up a pair of comfy red wings,,and a pair of timberlines for wifey,,The people ahead of us bought some moth balls,a couple foot of chain,,,Anyway,,,I looked at his ammo offerings,,.22short,,,.22long,,,.22wrf,,.22hornet,,,9mm,,,.357,,,.44,,,.243winnie,.257 roberts,25/06,thuty/thuty,.308,,30/06,,,and .300 winnie,,,,,F.W.I.W.,,,Clay

The m98 is a supurn action but it's horses for courses, I like the mauser derivitives for your 9.3x62's, .404's and the like !!

For stuff like the .300 RUM I have decided it matesbest with a rem 700 or similar. Although a rem for me will need to have some nice after market stuff on it for me to be able to mentally cope with it

If you want to do it cheap get your rum in a sps rem 700 there pretty cheap, and do your m98 action in a more traditional caliber.

Vent:

I am sure we will get a pro-Mauser, etc. fan flamer here shortly, but suffice to say, the Mauser has not been competitive in years. for that matter, no factory action is. The custom ones that are competitive are more similar to the 700. go to the library and get a book written by Jim Carmichel "The Modern Rifle." The title isn't reflective of the copyright, but it has lots of good stuff, as does Warren Pages "The Accurate Rifle."

books that are specifically aimed at the accuracy don't even mention Mausers, so don't buy them if you need convincing.

Or call Gordy Gritters.

I've owned more than a couple of very accurate Mausers. Nothing I'd compete with, but half the "one hole" rifles you hear about on this and other boards wouldn't stand a chance in a real BR match anyway. I think If I had the barrel and really wanted to use it. I'd find one of the Charles Daly magnum Mauser actions and use it. They are kinda cheap (quality and price). I'd try to keep the cost down because if you ever want to sell it, you're gonna take a loss. Might end up a real shooter. Stay with the .300mag

"I think Jim Carmichel compared it to a bank vault door closing" HMMM, well if that's what he believe's.

If a guy is building a rail gun then who cares about lock time? If a guy is building a hunting rifle then who needs benchrest components? Sheesh!

I have to agree with that. Like I said when I'm hunting I'm not looking for 1,000 yd rifle match!

Another thing what's up with this lock time stuff? I'm from the sticks of Oregon only time I here about it is here. The pre-64 I got and the model 30 I got I guess I better just get a cutting torch and cut them up cause Jim Carmicheal? said they have a slow lock time go out and get one of those new Remingtons everyone seems to be having problems with and dump about 1,000 dollars if not more into it to get it to shoot like these old pre64, model 54's and remington 721's and model 30's.

John

I mentioned Carmichel and Page because these two are writers who have more hunting experience than just about anyone here. they also competed; Page in BR and Carmichel in just about everything with a rifle. Page is dead and Carmichel is getting to up there in age as well, but what they wrote then still applies.

No serious target shooter, be it any discipline, uses a Mauser. For hunting, fine, but the question was putting a heavy target grade barrel on a Mauser.

Do what you want. I am just saying no one builds accuracy guns from these actions.

Do whatever turns your crank.

BTW, the pre-64 was never known for super accuracy.

I think various actions lend themselves to certain purposes better than others. There are rifle projects where I'd rather use a Model 700, Weatherby Mark V, or push-feed Model 70 action over a Mauser or pre-64 Model 70. If I were building an Ultra-Mag, I'd likely go with a Model 700 ahead of anything else. If I wanted a fine custom 7X57, I'd likely choose a 1935 Chilean Mauser ahead of anything else.

Since AZ mentioned Jim Carmichel, and since I know him as well and have hunted and shot side-by-side with him, I can tell you that Jim is anything but one-dimensional. He's devoted a lot of press to his fine custom rifles built on Mauser 98 actions that he's hunted with around the world, but I'll flat guarantee you that he wouldn't build a serious varmint rifle on one today, nor would he build a benchrest or high-power target rifle on one. Locktime IS important, particularly for certain applications (i.e. long-range), as is action stiffness, etc. But for general and dangerous big game hunting applications, the Mauser action offers undeniable advantages......

AD

My only point about the Carmichel comment was that it was an extreme exaggeration, that's all. I never questioned his abilities as a hunter, shooter, writer or his taste in custom rifles or his credibility. just pointing out it was an extreme exaggeration.

From reading the original post, I never got the assumption the man wanted to build a BR rifle. It sounded to me more like he had a barrel and wanted to do something with it. I think we all agree any rifle built on a Mauser action wouldn't be competitive in match shooting, but like I said that's not what I got from reading the post.

My take on it was he wanted to use the barrel and it happens to fit a Mauser action. Not a Remington or any other action, a Mauser action. Just because it's a Mauser doesn't mean it can't be made to shoot good. Like I said in the 1st post. I've owned some very accurate Mausers.

Lock time might be very important for match work, but the difference is minimal for informal target practice. The M98 isn't a flinklock. :^)

The point of my post was just to say I think the man could use his barrel. And build a fun to shoot, maybe very accurate rifle with a minimal investment of time or money and maybe learn something about rifles along the way. When the time to sell comes, he might lose a few bucks, but he wouldn't have much in it to begin with. Sounds like a fun project to me.

Well, as long as he doesn't insist on the .300RUM.

Terry

well said Allen.

Gentlemen,

To all of you thankyou. I am now ready to make a choice. I will searching out a CD action and I will go with a sythetic stock. Later if I just hate it, my little brother will have one hell of a deer rifle, but I will be happy if it will hit a dinner plate at 300 yards. I Bought the barrel on a whim and now it will be made into a hunting rifle. Thanks again guys-vv

Have fun!

Terry
