What Happened To The 300 Remington Ultra Mag?

[SeabeeKen]

With that level of performance, you need to go to an F-Open match and show them how it's done.

Bring a spare barrel.

Never played with the 300 RUM, I did have two senders in 338 RUM I wish I would have kept, still have a AWR in 338 RUM. I think the 300 RUM is slightly longer in the case if I remember right. My brother in law is still running his 7 RUM.

I went the 300 NMI route. Alex built the rifle, no regrets, love the rifle and the cartridge. He did a great job as he always does.

I'll never not have a 300rum...to haul freight.
Last two barrels have shot 230gr otm with n570 at 3150 in a 26".

East to tune cartridge.
Muzzle brakes these days are very effective.

The 300 Win mag is one of our armed forces sniper cartridges. They must have found an accurate load.

Never said it wasn't or couldn't be accurate. Just in my experience the Ultra is far easier to find a good load for.

The 6.5 Creedmoor, that's what happened.

Why would you need anything more?

Oh...the mighty "creed"
All a man needs...lol

I did my far share of winning with a version of the 300RUM. 404 Jeffreys necked down to .30cal. 40deg shoulder and a .310 neck length. Pushed a 240gr MK at 3000fps with MPR2. It was tough to beat.

i will never not own a 300 rum. 225's at 3,400 and suppressed is a thing of beauty

That range looks familiar!!

The 30-378 was designed by Roy for military experimentation in 1959, but not put into production by his son until 1996. Remington designed and produced the 300RUM in 1999. I fired several rounds in my first Remington factory rifle without a brake before it went to the Col. and had a bake installed. It was doable bake then, but not at my age and condition now. Ive got 2 300s and a 7mmone of the 300s is waiting for me to finish the stock. I like them but I think maybe they needed to have the shoulder pushed back .250. Jackie, still alive and well down here.

I shoot a wildcat of it, 338 edge.
You can get good brass for it thankfull

The same here, rebarreled and chambered in 338 Edge pictured below.

I started with a 300 WM, still have it. 700 in an Eliseo Tube Stock. But I like the RUM, no stinking belt to complicate head spacing. That said, I am having a switch barrel 300/375 H&H's on a Mauser 98 for a last trip to RSA. I just like the security of a claw extractor when I shoot at something that might kill me if I screw the pooch. I'd switch from H&H to RUM if it were not for the cost.

I am thinking about building an ELR rig.
My Cardiologist, who is also a fellow member of The Tomball Gun Club, is kind of in to it. He and a couple of his Doctor buddies have a place down between Corpus Christi and Victoria where they shoot out to a mile. He would like for me to tag along.
I would think the 30RUM properly throated for the big Berger 230 grn would fit the bill.
My other choice would be the 33XC Tubbs.

 

[DiffEQ]

As far as hunting goes, I think when berger came out with the high BC 7mm 180 gr bullet, a cartridge firing it made more sense in north am. than the heavier 30's???

I turned my 300 RUM into a 7 LRM, and converted all my RUM brass to use with my 338 Edge.

 

[R.Morehouse]

I had a RUM and enjoyed it a lot with the 230's. Got the 300WSM bug and it morphed into that for quite a while. Traded up for a beautiful 338 Lapua improved put together by Masterclass and Goodling and shooting the Berger 300's at over 3100 out to faraway places is some of the most fun this guy has ever had behind a gun. I would never let this boomer go, it is a nice alternative to the 6ppc & Dasher when I get the itch.

People probably realized

1: really large magnums suck to shoot in light hunting rifles
2: Large Magnums aren’t needed to kill 60lb southern whitetail or bigger game for that matter.
3: Remington sucks at marketing and getting the industry on board.

I had a 7mm RUM and went back to 30-30 and 30-06.

Thanks for clarifying the timeline on the .300 RUM vs. .30-378. I edited my post accordingly.

yeah we switched to 7mm Dakotas---now that brass is scarce.

Very similar, the 28 Nosler is the most common used gun I see at stores.
