300.wsm vs. 300 rem ultra mag.
 

I am looking for a powerfull, flat shooting rifle that will be able to cover a variety of situations and wild game. I am a traveling madical technologist and would like to purchase a rifle that may cover a variety of wild game across the U.S. I am looking at the new 300.wsm or the 300 rem. Ultra mag which one would be the more powerfull and the flattest shooting of the two

RE: 300.wsm vs. 300 rem ultra mag.
 

The ultra by a good bit .. But you will also feel it on the other end ..If you hit anything in the right spot it will be just as dead with either .. Bill

300 wetherby.

RE: 300.wsm vs. 300 rem ultra mag.
 

The .300 RUM is the flattest of the two. It will handle anything in NA, and keep asking for more. Good luck on your purchase!!

RE: 300.wsm vs. 300 rem ultra mag.
 

300 RUM gets my vote

RE: 300.wsm vs. 300 rem ultra mag.
 

RUM is definately slatter shooting and more powerful, espeically if you reload as this cartridge has a lot of capabilites not seen in factory ammo.

RE: 300.wsm vs. 300 rem ultra mag.
 

I've owned and shot both. The RUM is the flatter shooter, but its recoil is considerably more than the WSM. Unless you have coastal bears on your hunt card, I'd forget the RUM and get the WSM. The 300WSM is the most popular WSM cartridge out there, and ammo is rapidly becoming available in places where it wasn't just a year ago. The RUM, while maintaining a degree of popularity, is losing market share (or so a Rem rep told me about 3 months ago).

RE: 300.wsm vs. 300 rem ultra mag.
 

I own two 300ultramags and for my uses they serve me well.However The ultramag offers no real advantage until the ranges approach 400 yards and then only if you are willing to spend considerabletime and money to develop and maintain the shooting skills that are necessary to accurately place bullets at 400 yards and further.Recoil is also a factor for some people.

RE: 300.wsm vs. 300 rem ultra mag.
 

300RUM is great if you reload and can handle it effeciently. If not the 300 wm or wsm would be a better choice. Either will allow you to hunt near anything in NA, at ranges most don't feel comfortable shooting in the first place.

RE: 300.wsm vs. 300 rem ultra mag.
 

300 RUM has alot more recoil than a WSM and not that big of an advantage.

RE: 300.wsm vs. 300 rem ultra mag.
 

why in the would would he want a weatherby?:)

I have had them all. The RUM is more powerful by a good lot. I was kicking 180gr bullets out at 3350fps. I hate the freebore and belt of the weatherby. And more expensive to reload.And much more expensive for factory ammo.But, but, you can get top quality brass for the weatherby. Which isa plus.

But honestly, I have had it with the RUM and weatherby. I burned out one barrel completely under 1000 rounds. And the last one was a custom had heat cracks within 500 rounds. I loved the power of the round.

So for me, I only go with the win mag or WSM. Take your pick. I am a Short action guy, so I go with the WSM.

RE: 300.wsm vs. 300 rem ultra mag.
 

How do ya figure? Is this what you have found wth your WSM and RUM's?

RE: 300.wsm vs. 300 rem ultra mag.
 

The 300ultramag provide superior ballistics without the weatherby freebore.



Just how much experience do you actually have with these cartridges?

RE: 300.wsm vs. 300 rem ultra mag.
 

The RUM is excellent. A friend last week bagged a nice elk here with his at 477 yards (measured on a laser rangefinder).

RE: 300.wsm vs. 300 rem ultra mag.
 

300 wsm, i just wouldnt want to put up with that ten extra ft pounds of recoil.

RE: 300.wsm vs. 300 rem ultra mag.
 

Now that the dinosaurs are all gone, I will stick to the 308 for a 30 caliber.:D. If I needed a Magnu it would be the 300 Win Mag or 300 WSM.

RE: 300.wsm vs. 300 rem ultra mag.
 

James, James James, how many times do you need to be told, it ain't about need. Nobody needs a rifle for hunting. In fact your 308 is overkill compared to a bow. Thats all we need, but it is sure fun getting payback for them critters staying out of range during bow season.

RE: 300.wsm vs. 300 rem ultra mag.
 

Chuckhawks is where I found most of my info about 300 RUM and WSM. Wsm is alot more popular around where I live and ammo is much cheaper. I don't think the ballistic advantages of the RUM over the WSM is enough to put up with the high shell cost and high recoil.

RE: 300.wsm vs. 300 rem ultra mag.
 

Well, it depends. Number one, I would never use a 300WSM or 300RUM on deer. But when reading all these internet pages, people tints thier articles on thier rurthers. For instance, at 500 yards with a 300RUM you would have the same energy and velocity as a 300WSM at 350. Now thats a big statment. Now, as a person who has shot at moose that far, yea it matters. Its a big heavy boned animal that can be tough.

I agree the WSM is the way to go for most hunters, but I base that off of actually having both.

RE: 300.wsm vs. 300 rem ultra mag.
 

It should also be mentioned that the 300wsm is loaded quite hot from the factory,while the factory 300ultramag loads are very mild.When you use handloads,the gap widens significantly.

RE: 300.wsm vs. 300 rem ultra mag.
 

I have the model 700 Rem, 300 Ultra Mag Sendero, SS, Fluted, 26 inch barrel. I hereby bare witness to what the 300 Ultra can/will do, its a bad dog.. I have consistently shot and killed deer at 400 yards (measured with range finder) with no problem. I use the Rem 180 gr Swift Scirocco sighted in at 2.75 inches high at 100 yards, and it is one flat shootin' - killin' gun/bullet. Man, it drops 'em in their tracks. My motto for my 300 RUMis "Something Wicked This Way Comes".

RE: 300.wsm vs. 300 rem ultra mag.
 

Don't be caught up in all the latest wizbang offerings from firearms manufactuors. They are in the business to sell thier product.
IMHO you have to look at the factory offerings to compare rounds. The 300 Win Mag and 300 Weatherby have been around along time now. With todays bullets and powder they are still good choices. I personally limit my shots to 300yards for animals larger than deer and 400 yards for deer sized animals. Those are ranges I know that I can make good clean one shot kills under hunting conditions. Both the Win Mag and Weatherby have fine repitations in the field and on the range. Free, Schmee don't let anyone put the thought in you mind the 300 weatherby isn't a very acurate round.
All that being said I would have to say the 300 WSM would be of interest if I was in the market for a new 300 round. If you handload you have to look what goes in (powder amount) and what comes out (recoil and velocity) When you stuff all that powder into a RUM it's going to go faster, it had better. But the queston should be how much powder does one use to make all rounds equal say for the sake of argument 3100 fps and you have a 3200 fps RUM that uses 10 grs or more ( alot of powder)to gain 100 feet. That's the dirty little secret handloaders fail to tell when they post.

RE: 300.wsm vs. 300 rem ultra mag.
 

Ruddy, what do you think happens with a 270 and you add 10 gr of case capaicity to it? You get 100-200fps gain. Ok, stay with me. What would happen if you expanded the 308win case to hold 15 more grains of powder and actually added it. You would have WSM that gets about 200fps more velocity.

Ok, I know its difficult to wrap your hands around, but for any case you have to add more powder to get more velocity and stay under safe pressure limits. Understand? If you don't, I can help you more later.

RE: 300.wsm vs. 300 rem ultra mag.
 

Wow!A larger case and more powder increases the velocity,what a concept.Now everyone knows the secret.:D:DSo the RUM burns 10gr more powder to gain 100fps to 125fps over the 300wby,big deal.Is the cost of that extra 10gr of powder going to break your budget?Considering that my 300 RUM handloads cost less than somefactory loads for cartridges like the 30-06,I couldn't care less if I burn a little more powder.If you are so concerned about efficiency,shoot a 30-30 and live with the limitations that it's ballistics demand,and let those nastyhandloaders practisetheir dirty little hobby.:D:DThen again maybe some day you might actuallybe able to understand theconcept of handloading,and you might even get over your fear of those big bad RUMs.:D:D

RE: 300.wsm vs. 300 rem ultra mag.
 

The point is you can take say 300 win mag add a grain or two and walla, you have ballistics equal to the RUM factory load at with 10 grains or moreLess powder. Most people don't handload and was making sure that someone doesn't get deer in the headlight look over ballistics thinking the RUM is the second coming.
I understand handloading and all that goes with it. Been there got the T shirt, Know about strecthed case , flatten primers etc etc. It's a fine hobby and one gets enjoyment out of loading one's own. I gave up reloading about 10 years ago when I discover some factory ammo was giving accuracy performance the couldn't be improved upon. I believe 1/8 -3/16 groups center to center would be hard to improve on out of a hunting rifle.I love how insults can fly. Fear I don't think go considering I owned 300 weatherby's over 30 years ago , along with a 338 in the past and presently have two 375 H & H 's hopefully to go to Africa in the near future.

RE: 300.wsm vs. 300 rem ultra mag.
 

Have you ever shot em ruddy?:D Might want to think about that before going to Africa. Just reading about em isn't going to get the job done.:D

No offense, but with your original post, its very hard for me to imagine you reload or ever had. Hardcore reloaders on here would probably agree.

I have never had a 300win mag or weatherby that could close to the performance of a 300RUM. I have yet to ever see a 300win mag come close to 3350fps with 180gr bullet.

RE: 300.wsm vs. 300 rem ultra mag.
 

Ruddy you don't seem to make much sense. First you said you have to compare factory ammo to factory ammo to compare the different cartridges, (by the way is definately not true if you ever want to reload), then you say that if you add powder to a win mag (which is reloading) you can get up to RUM factory performane. That is comparing handloading to factory. And if you somehow are getting 1/8 in groups out of factory ammo that is pretty incredible and i also wouldn't reload. Kinda hard to believe unless you're using the best custom rifles.

RE: 300.wsm vs. 300 rem ultra mag.
 

The point is factory loads are close with different offerings and what one puts into a round and what one gets out. Most people don't handload. I don't believe the RUM is an efficient round when you look at how much more goes in and what come out.
Try some Hornady and Federal premium rounds if you don't believe you can't get factory ammo to shoot like handloads. I've put various boxes thru a crony and got a max of 20fps deviation.
And to those that like to throw around insults , I was shooting while some were in diapers and worked at a commercial range for almost 15 years. I've shot just about every thing imaginable from 22 shorts to 50 bmg's . You shouldn't use your mouth for breaking wind son.

Wow,what ashameall those years, and still havn't learned anything. Still having trouble with the concept of more powder means more velocity.Well not everybody can be top of thier class. But don't worry, your still special.

RE: 300.wsm vs. 300 rem ultra mag.
 

I think we need to look atthe different types ofhandloaders to better understand what is being said here.There are those of us that spend a great deal of time developing loads and testing different component combinations and seating depthsuntil we discover which load will provide the best combination of accuracy,velocity and bullet performance on game.These are the people that really understand the concept of load development.Then there are those people thatsimply choose aspecificload printed in a manual and load it up and hunt with it.They assume that just because it is a handload,it must offer superior accuracy and performance and if it doesn't they condemn handloading as a wasted effort.These people may consider themselves handloaders,but they really have no comprehension of load development and their efforts often produce results that offer no advantages over factory loads.

RE: 300.wsm vs. 300 rem ultra mag.
 

No offence intended but I think you are completely missing the point of a cartridge like a .300 ultramag. It isn't designed to be efficeint but rather to deliver .30 cal bullets at long range with high velocity and energy. If you want something effecient then a 6.5 Swede comes to mind. But if you want to ( and are capable of ) take 400 yd shots at heavy game like moose and elk then the Ultramag is going to be a more effecient killer even if it burns more powder per foot per second. When you point a rifle at an animal you should worry about the shot killing as quickly as possible, not what it costs per round.

RE: 300.wsm vs. 300 rem ultra mag.
 

you forgot one stubble..........the guy who reloads to slightly improve accuracy but save money. I got into reloading because when I bought my 300 RUM I didnt want to pay $35-$40 a box. Now I reload for all of my rifles and I have all of them grouping between .75 and 1.25 and am saving money. I dont redevelope loads or even improve them. If I consistently shoot 1.1 out of my 06 then I stay with it. :D
