300 magnum or 300 ultra mag

[Supergrit]

Wondering what peoples opinion are on these two Claire's. Also wondering how much faster a barrel on a 300 ultra mag would were out compared to the 300 mag.

[trigger7mm]

Go with the 300 Win. mag. It will flatten anything Alberta has to offer, and ammo and reloading supplies are easier to acquire.

[bezzola]

Go with the 300 win I had a 300 um and it was ugly to shoot

[elkhunter11]

You are talking about one caliber with different cases behind the same diameter bullet. And 300 magnum in itself doesn't designate a cartridge, as there are several 300 magnums, as in 300wsm,300winmag,300H&H, 300wby etc.

[colroggal]

My two pennies. If you're hunting/shooting inside 300 yds go with a .308 winchester. 400 yds get a 30-06. Past that is the only time you NEED a magnum .30. That said, the RUM's get past the pressure barrier with extended freebore and by most accounts that translates to a much shortened barrel life.

That said, if it's a hunting rig that might see less than 50 shots a year between filling a tag and practice, you still have 15 years of life at the least.

Again, my .02.

I took it to assume the op meant a .300 winchester magnum. But you know what they say about assumtions...

Weatherby uses a gread deal of freebore in their rifles to achieve higher velocities, but most RUM rifles have quite normal throats. I have personally owned two 300RUM rifles, and I could load to the lands, and the loaded ammunition would still fit in the magazine. The RUM cartridges do have fairly short barrel life, but it'd due to the very large case capacity, not extended freebore.

I took it to assume the op meant a .300 winchester magnum. But you know what they say about assumtions..

I prefer to interpret people's questions as they are worded, rather than start making assumptions as to what they might mean. I have personally witnessed someone asking for 300 Remington magnum ammunition in a store, and I have witnessed one person shooting 300winmag ammunition in a 300wby rifle, because he thought that all 300 magnums were the same, so he bought the cheapest 300magnum ammunition in the store.

I'll advice you go with 300 win mag...

[The Spruce]

I shoot a 300 RUM in a Remington sendaro, tack driver, love it. If you are not concerned about ever shooting over 300 yards, stick with a 300 WIN, possibly over 300, to 500+ get a 300 rum. The RUM will take anything anywhere you go accurately out to 500 with little effort. Put in some time, get a good scope and 800-1000 is doable. Personally I will never shoot a different round.

[The Spruce]

Oh, as far as the barrel goes, I have put 250 rounds through my gun, no issues, tight groups. It would really depend on what kind of barrel you are using. Light stainless or blued steel, you will see heat issues with both rounds. Heavy barrels, no issues with either.

[Sharpie]

So a .300win is only good out to 300yds???????????????????????????????????????????? ?????????????????????????????????????????????????? ??????????????????????????????

[JustBen]

That RUM is good for beating up your shoulder, but not much more effective than a 300 WM. Realistically! the 300 WM is good to 500, but how many animals have you honestly needed that kind of distance for?

90% of all kills will be less than 200 yards. Probably 75% will be less than 100.

250 rounds is hardly a measure of barrel life, it's a year or less of shooting, for the serious shooters that have the skills to shoot accurately past 500 yards. Depending on how you treat them, 300RUM barrels can have the throat totally eroded by 400 rounds, or they can last over 1000 rounds if not overheated, and properly cared for. On the other hand, a properly cared for 300winmag barrel will handle twice as many rounds before the throat is eroded to the point that the accuracy is significantly degraded.

In all honestly, the 300win mag is a far better choice for the vast majority of shooters, as the vast majority of shooters don't even have the shooting skills to accurately place bullets at the ranges that the 300RUM is capable of.

And if you don't handload, I wouldn't even consider the 300RUM, as factory loads are very mild, and don't provide anywhere near the cartridge's potential.

[glen d.]

You want the longest reaching flat shooting gun, especially for elk, with good hitting power, i believe the 300 ultra mag would be it. Do not have the specs in front of me but i think they only a drop of 25 inches in 500 yards wow, that why we bought them.

this is important to note

you could basically end up paying for very expensive 300 win mag ammo depending on what "power level" you shoot

[edmhunter]

Does anyone know the answer to this question between the 300 Win Mag and the 300 Ultra Mag. Looking for a new rifle and want one that can shoot at long range, if and when necessary.

Enough Energy at 1000 yards to kill elk is what I want to be able to do, only if required, may never need it but would like to know that my next rifle can do just that.

What is the max distance effective range, (killing power) on a Win Mag?

What is the max distance effective range, (killing power) on a Ultra Mag?

So all those 550 yard rams I tip over is a bonus because I only went with the Win Mag? Maybe just lucky?

Seriously though the 300 Win is quite capable to well past 500 yards.

To the OP. If you are a reloader then you can consider the RUM. If not then I wouldn't bother.

Here's the comparison. RUM will shoot faster and flatter. It will also have substantially more recoil in the same stock style and more noise. It is much more difficult to find ammo commercially for.

As for the over 300 yard stuff... Who cares? If you are dialing a scope, and any responsible shooter will dial and not just fling lead with Kentucky windage, what is 32 clicks instead of 27? Simply 5 more clicks. Nothing more.

Here are some numbers from iSnipe.

300 Win Mag, 180 grain Speer bullet with a max load of IMR 4831 is around 2950fps
300 RUM is 3160 with a similar bullet and the same powder.

With a 200 yard zero the Win Mag is going to drop 42 inches or 8.04 MOA at 500 yards.

The RUM will drop 36 inches or 6.85 MOA.

The Win Mag will be at roughly 1800 fps, which is what some bullets need for velocity to reliably expand, at 575 yards. The RUM will be there at 650.

5 clicks and 75 yards. Not that dominant after all. I guess my Win Mag is just fine.

[Sharpie]

Ive droped a elk and a few big mule bucks in their tracks, at or just shy of 500yds with a 168gr out of my .30-06. I debated the same thing .300win or .300RUM for my next gun. It will be .300 win which i think is cable of taking moose and elk at 800 yrds. If i cant get closer than 800 yds something is wrong with me. But then again the way my .30-06 has treated me, why buy a new gun.

It will depend on the bullet chosen. Many bullets require a certain velocity to reliably expand. Find out what that velocity is and that point is where the bullet may or may not work. That is how I determine what the acceptable hunting range is for a bullet and cartridge combo. See the comparison above. Not all bullets work on the premise of a static 1800 fps. It is just a quick guideline I used for the comparison.

[edmhunter]

Just got off the phone with Corlanes, was told the following:

300 Win Mag 180 Gr. at Muzzle: 2,950

300 Ultra Mag 180 Gr. at Muzzle: 3,270 and they etch the turret on the Huskemaw up to 1,100 yards.

Thinking that the Ultra Mag will be my choice.

[north american hunter]

I owned a 300 ultra mag for a coupke years, recoil was pretty bad, and recoil doesnt bother me that much, win mag or weatherby would be my choice.

[fish_e_o]

i was not really a fan of the ultra mag when i owned it. flat shooting, picky, quick fouling, heats up the barrel like crazy, uses tons of powder.

edmhunter my opinion, for your set up, is that if you are dialing a scope trajectory is largely irrelevant. go for a better return on your investment and a longer barrel life. elk at 1000 yards still aren't bullet proof i doubt you'll have an issue with either.

What would be your recommendation? Thanks fish_e_o.

honestly whatever turns your crank

all the 300's and 30 cals shoot the same bullets.
trajectory imo is irrelevant because you're dialing a capable scope.
you want high retained energy so maybe a "magnum"

the good old 30-06 could probably be used components everywhere, everyone and their dog has one, and you'll blend right into the crowd.

wsm's have the efficient case design principle and also a shorter more rigid action. they can feed clunky

300 win mag has slightly more power than the wsm and capable of excellent accuracy. i find i like the belt because it's something to hold onto when your fingers are frozen

300 weatherby even more power rounded shoulders for "smoother" flow so i'm told. a nice belt for frozen fingers. i always thought he was good at developing cartridges for right around the top of the velocity mark as far as investment from powder was concerned.

30-378 weatherby pretty much your 300 rum just cooler and more hip. also has a belt

300 rum has the word ultra in it.


now if it were me and i was bored and brave enough to build another gun to bring into the house in a 30 cal i would strongly consider the 300 weatherby. stuff is available and high enough quality. and it's the same price to reload as the others but you can brag about how expensive factory ammo is to your friends. but i also like my 300 wsm because i went through a stubby cartridge phase.

[kirbstomps]

i shoot a 300WM, and trust it well past 500. My 2 Cents is if i was going to shoot a 300 Ultra, i would just go with a .338 Lapua instead

[schreyer]

When zero'ing at 200 yards with my 300 win mag, I noticed that the 10'' diameter poplar holding my target was not holding up too easy.

So if my 180 gr. Nosler can punch through no problem, I don't think a moose will outlast it either.
