So with that thinking a 30/378 weatherby would be like 6 rifles in 1?
Wow....I’ll have to pitch that to my wife..

Seven

Cpl knows what he knows, what you guys don't understand is that he plans to fly those 178 ELD's in a 300 RUM cartridge in the Bombay doors of his Cabelas drone straight to the target and pickle it 2' over the target. Now that is flat just like he says. You guys are just imagination short. MB

.300 RUM/225 ELD, 7WSM/180 ELD. I used my actual velocity in the 7WSM with 25" barrel and compared both using pressure-tested data and QL. I gave the RUM every advantage I could- 1000 psi higher peak pressure, an extra inch of barrel, etc. Sucks to burn nearly 40 gr more powder with every shot, and still come in 2nd place

This is awesome data!

This belongs in the UFO thread. Lol

The most lame-brained cartridge ever produced!!

Thank you Jordan...And that is why I own both. A 7WSM and a 300 Ultra. I hate 3rd place finisher. 😎

The '300 Remington Ultra Magnum Cartridge' performance speaks for itself but Hornady makes these ELD bullets
and they stand behind the 300 RUM .

" The 300 Remington Ultra Mag. in factory loads can push a 180gr bullet out at 3,300fps from a 26" barrel.
Given the cartridge's preference for slower burning powder's, the long barrel helps exploit the full potential of the round. "


" The new 220gr ELD-X bullet was designed for cartridge's like the 300 Ultra Mag,
where you can combine a low drag, accurate hunting bullet with a profile that doesn't require seating past MAX COL."

You're trying to pass the koolaid, not lead to water.

So w

So what does a 180gr bullet and a 225gr bullet have in common ? … NOTHING !!!

If you want to compare Bullet's and Velocities of a 7 WSM & a 300 RUM :


…………. 7 WSM …………….300 RUM ………...
………. 175gr ELD-X ……….178gr ELDX ……….
…... 71.0gr - MAGNUM ….. 90.2gr - RL - 26 ......
….........2,900fps .................. 3,250fps .................


Only 19.2gr more powder with a velocity increase of 350fps.
Below is a picture of Cartridges as an example of 30 Cal and 7 WSM.


The Thrill of Victory .... The Agony of defeat

We had a wall plaque in our holiday trailer. It read, "Before you shoot your mouth off, make sure your brains are loaded!"

You sir, have failed to abide by that slogan.

Why do you think this thread has gone on as long as it has? It's not because it is insightful, to the contrary, every time you post, you demonstrate what you don't understand.

Most of the posters are egging you on, but you don't understand that.

I'm glad you like your 300RUM. But it is an extremely inefficient cartridge. To help you out, an inefficient cartridge is one that burns excessive amounts of powder to gain diminishing ballistic gains. I shoot a 300WSM with a 168gr bullet and Reloder 17. Alliant powder does not list the 168gr bullet or Reloder 17 in the 300RUM, so I'll use Reloder 22 which is listed for both cartridges.

The 300WSM and a 165gr bullet can achieve 3125fps with 73grs of RL22.
The 300RUM and a 165gr bullet can achieve 3268fps with 93grs of RL22.

I will admit RL22 is not slow enough to maximize the cavernous capacity of the RUM, but it is a straight comparison that demonstrates that the RUM requires 20grs more powder to achieve 143fps more velocity with the same bullet. Is the animal any more dead or the rock any more split with 143fps more velocity? Nope. But your barrel will burn out faster than my WSM and I can load 6 WSM rounds for every 5 RUM you load. The RUM is even economically inefficient.

Back in the days before good laser rangefinders or ballistic reticles or tactical turrets, some people felt that shaving even an inch off the trajectory could make a difference between one more xring, or a dead deer. I still practice maximum point blank range. I know my loads, so I sight in so that I am pretty much dead on at 300yds and my bullet is never more than about 4" high. My MPBR is about 330yds or wherever the bullet dips below 4" below line of sight. If you use this correctly, if I hold dead on the center (height) of a deer's chest, I will not miss that deer and will kill it anywhere from the muzzle to 330yds. Even at 400yds, I am 11" low, 26" low at 500. MPBR has worked for me for 35 years. To sight in differently screws my brain up.

Now days, a shooter or Hunter, with a rangefinder and a scope with a ballistic reticle or turrets can do anything a RUM was designed to do with a 308Win or a 6.5 Creedmoor. Less powder, less recoil.

Enjoy your RUM, but if you want posters to stop laughing at you, stop posting on this thread. To keep posting you are confirming the old adage: "If you think people think you are an idiot, open your mouth and confirm it."

So let's assume that your comparison above is the correct comparison to make, which it is not. Your bullet gets to the target with less drop. The 7WSM gets there with less wind drift. If you've done any amount of long range shooting, you would understand that wind is the hard part. Elevation (drop) is easy. Congratulations, you've used 30 grains more powder to make it harder to hit the target.

Now, if you insist on using the 178 in the 300 RUM, which I wouldn't, a better comparison would be to the 150 ELDX in the 7WSM. The WSM is both flatter and drifts less. Comparing bullets of the same weight across calibers is a fail.

Cpl_Austin - take the cerebrum off of autopilot for a moment.
Comprehend and actually absorb what rovert has laid out above.

And, I suppose congratulations are in order - it's been some time since someone has given Jeff O a thick-headed run for his money on this forum.

Getting somewhere first is better than arriving at the right place. Applying Capt America’s thinking. 😎

I like the .300 Weatherby.

When I hunt and shoot, I never look at a chart, I just kill stuff. I had a 300 WBY, but my brother talked me into a 30-378. It didn’t take long to get over that and I went back to the 300 WBY.

I have found the 300 WBY to be the most for the least in the 30 caliber magnums. Anything more is too much of not enough, anything less is not enough of too much...

Too late...
