300win mag vs 300 rem ultramag
- Thread starter daniellybbert
- Start date
300 RUM tosses a 200 grain Accubond over 91 grains of Retumbo @ 3200 FPS out of a 26" tube. My 700 BDL S/S will group inside 1/2 MOA if I do my part. BE PREPAIRED FOR SOME HEAVY RECOIL THOUGH! Not a caliber for those not use to a magnum rifle or develop a flinch easy. Delivers a sh*# load of energy on target and is likely overkill for anything short of Grizz or Bison in N. America...but non the less a hell of a fun shoot.
The 300 Win Mag is ...well....OLD....PROVEN....and easy to get ammo for....but yawn...a belted magnum..kinda like black and white TV.

i like the 300 win mag its tryed and proven and dosent beat the liveing hell out of you. ammo is cheaper, easyer to find, uses less powder, dose not bern the bbr as fast.
some cons are : will not throw the lead as fast as the UM, has a more drop over long ranges, less energy, and every one on the block has it....(or almost)

RUM has 300 fps more snot out of the gate and 750 Lbs more against the wall with factory ammo. Reloading can drive the RUM 3200+ with a 200 gr bullet putting it in the same group as the 30-378, and the Lazzi warbirds.
You can get 1000 ft Lbs more out of the RUM over the Win Mg. This is huge! if you can control the power with the right bullet selection.

I agree Gatehouse and know what your saying, It only takes a certain amount of energy to do the job and at 100/200 yards whos to tell the difference? The 300 WM is a bit more versital when it comes to bullet selection and smaller game, I believe you can load it down for deer and not have to worry about a splatter effect as much with a softer bullet if hunting deer, as the 300 Rum will have a shot gun effect with a soft point and with a bonded bullet like a tripple shock I have seen my 30-378 not open and pencil a deer putting 3000FT Lbs in the dirt behind it! still killing the deer of course.
Take it or leave it theres alot of powder being burnt in the Rums there not that efficient for the amount of fuel they burn.

I went with 300 Winmag because I know that I can get factory ammo for it in a wide variety of loadings at a price ranging from $22-$50.00 a box. I've also seen what can be done with it and while it may not be ultimate, its more than adequate.

There is only one choice as far as I'm concerned for a long range hard hitting cartridge....
280 Ackley Improved!
From Nosler Fifth Edition:
300 RUM w/180gr BT max velocity = 3225 fps (96gr H1000) 26" bbl
280 Ackley Improved w/140gr BT max velocity = 3196 (63gr RE22) 24" bbl
Ballistics:
300 Rum 180gr BT @ 3225fps w/300yd zero:
100yds : 2.95"
200yds: 3.63"
300yds: 0.00"
400yds: -8.43"
500yds: -22.34"
280AI 140gr BT @ 3196fps w/300yd zero
100yds : 3.06"
200yds: 3.76"
300yds: 0.00"
400yds: -8.74"
500yds: -23.36"
Here is the major difference between the two:
RECOIL (Ft/Lbs) in 8lb rifle:
300 RUM w/180gr @ 3225fps = 42.16 ft/lbs
280AI w/140gr @ 3197fps = 21.91 ft/lbs
I can guarantee you that NO ram, moose or elk for that matter will know the difference between the 2 cartridges out to 500yds with a good bullet and a good solid hit.
Why go through the extra punishment, powder, and expense?

Gatehouse said:(If you dont want to bother with the mucking around with a 280AI, then you can always buy a 7mm Rem Mag. Not as ###y, but similar ballistics, and the 7RM will outperform the 280AI wiht the heavy bullets, too.)
Beat it, don't be so practical (grin)!

280,
I notice all you post is a volocity comparison...where's the ft pounds of energy comparison between the 140 and the 180??? There isn't a comparison for just that reason...The .308 will come out way ahead, specially because it maintains its volocity and trajectory better than the 280AI. Thats right flatter shootin' delivers more energy on target at range. Why not compair the 280 AI to the 7mm RUM for giggles???????

I don't make it a habit anymore to get into arguments with the Ballistically Challenged.... but here goes!
Look at the trajectories I posted, there is 1" difference at 500yds. Doubt even you are good enough to tell the difference in trajectory between the two.
As for energy difference at 500yds..... it shows again your ignorance.
The "Experts" claim 1500fpe is the magic # for dumping larger critters (if you put any merrit in FPE which obvioulsy YOU do).
The 280AI is still packing 1608 fpe at 500yds (More energy than the 30-30 Win (170gr @ 2200fps) has at 25yds).
Do you honestly believe that a well placed 180gr from the RUM at 500yds is going to make a world of difference over a well placed 140gr from the 280AI?
Me thinks not, and a poorly placed one from either is going to be equally troublesome!
Like it or not, the 300RUM was born simply as a marketing ploy, not to fill a niche of killing critters that couldn't be slain by existing cartridges.

Since the thread has already been hijacked, IU will wade in. You could not EVER see me toting a 26"landcannon in sheep country! Light sporter rifles in 25-06 through 280-7mmRmag are MUCH better suited to and shooting done in the mountains.
The ORIGINAL question- There is very little if any true difference in the field performance in the 300v 300UM under field conditions, Any difference will be entirely due to shooter/rifle dynamics.

I asked the same question you just did about a year ago. I wanted a .30 cal magnum for moose and what not.
I ended up deciding on a .300WSM.(Since sold it anyways) Great ballistics for wayyyyy less recoil than either the WM or the RUM.. I shot a .300WM and .300RUM. The recoil from the RUM was just retarded, way to much to make a comfortable shot from a field position. The WM I shot was in a Sav 110, so with that 6.6lb rifle you can imagine the kick.
Like gatehouse said, not to many guys can shoot well enough to take game at the extended ranges where the RUM might actually have some advantage. That is why I chose the WSM.
Gonna get another Someday.
