I'm thinking about getting a 375 RUM. I assume I'll have to buy Remington. How good is their gun? What barrel lengths do they offer? Is their gun accurate? Do you have any load recommendations? Thanks ahead of time for any advice. Regards, AIU

I used to own a rem 700lss in 375rum, very accurate but was way to light and I did not like the fact that it came with no open sights.Also for a box of factory 300gr aframes was costing 72.00 a box..i traded it off for an h&h..

There are people on this forum that I respect very much who don't like the .375RUM at all. I can only speak of what I know. I have shot 20+ African animals incuding lion, buff, eland andleopard. I shoot 300gr Barnes X and they are devestating on game. There is no substitute for shot placement but if the .375RUM is placed properly then you will be very pleased with the results. I used a .375AI on my first two safaris and killed buffalo on both safaris. Based on my observations I think the .375RUM hits harder resulting in quicker kills. Ask others on this forum because their experiences may be different. You need to be careful because you hear a lot about"I heard about" this and such. I'm telling you what I saw and what happened on my own safaris. If it were different, I would tell you because I also like the .375AI very much. On my last safari in Kisigo, Tanzania, I had one shot kills on two buffalo, an eland, and other plains game. The 300gr X is a very fine bullet and I'm sure my results are dependent on this bullet's performance.

The real question is how soon is it going to be an orphan?

I don't shoot it myself, my main data points are Saeed's experiences with his .375-.404s: which argue that it will work well indeed.

Of course Saeed is a great shot too, which is a major consideration.

I will check some data and see if I can get an estimate on the orphan factor.

It's damn good!

Not TOO soon if more people would try it and buy it.

I chose it over the H&H not only because it came in the Remington 700 platform that I'm comfortable with using, but also because it was MORE than the .375 H&H.
The .375 H&H seemed to constantly be under scrutiny, with many people 'improving' it or 'Weatherby'ing' it, or something or other.
The .375 ULTRA MAG just "had it" to begin with, and as mentioned, is a ballistic twin to Saeed's .375/.404, which HE said is a good choice!
All that cinched it for me.

I hope the .375 ULTRA MAG remains with us for a long time.

Its like anything else,if you want the power go for it. Some of the folks who will try to talk you out of it are the same ones who will try to talk you into a 300 mag over the 06, go figure. I say thumbs up <S>

It's not exactly something one uses for prairie dogs so the brass should last a while.

Buy the gun and buy acouple hundred brass with it. You'll have a lifetime supply should the cartridge go bum in the night.

I'm a fan of the H&H round and sticking with it but Saeed's recommendation carries as much weight as can be had. Few have had the experience he has had.

Ask Saeed,
his 375/404 is the ballastic twin of it.

this MIGHT be the best of the "bigger than 375 hh"s (like 378 weatherby), as it IS useful in factory loading and can be loaded down to whatever the shooter likes


savage and remington made them. I THINK winchester made a run

There's another way to have a 375 Ultra and that's to just run a reamer through the chamber of an existing H&H rifle if you have one. Open up the rails, get another floorplate with proper spring since it's a bigger round and glass it. I started that project a while ago with an extra RSM and find that accuracy isn't hurt with the existing twist of barrel. I'm not finished with it yet as time just eats away at my projects. I've always wanted one since Jon Sundra first wildcatted the 375 from 300 Ultra brass and wrote it up about a hunt several years ago. Since Saeed has been using his version with his home made premium bullets, it's proven itself over and over.

Re: Orphan factor

I checked my cosmic top secret source for sales data on the RUMs.

It looks like the initial surge in buying the RUMs has faded away, and the .375 RUM was not a big part of that.

You can check your local shop and see if they even stock ammo. Orphan is looking like a good bet.

I think it's apretty good cartridge, similar to the 375 Weatherby. I firmly believe that given properly constructed bullets, velocity does offer added killing power. At least that's been my observation. jorge

I have the Rem Custom Shop ABG(the old school one, not the 2005 model), and it so far has not had a feeding problem at all. Granted, I do not use/shoot my rifle every day, but it works. It has a 26" barrel with the NECG Masteroiece front and rear sight.

Some folks will cry REBATED RIM! But the difference between the 404 case and the RUM at the rim is like .002". If I am wrong on that measurement, please let me know. Take that for what its worth. The mag is single stack, so no "the left round loads fine but I have to pay a gunsmith ot get the right round to load" problem.

I load 250gr Northfork softs and the 300gr cup points, both function fine. As far as ammo availability, I would rather load my own than pay $50 to $70 for 20 rounds. And who knows, maybe pretty soon brass wont be readily available. Buy a bag of 500 or some stupid # like that and you will never have to worry about brass for the rest of your life.

The only thing I dont like about my weapon is the bolt handle is soldered on, not machined. That right there would be the only reason why if I did it again, I would not have purchased the rifle.

250NF Soft
3.595 OAL
2.840 case length
Fed 215 Primer
92-96gr RL22(limited testing unfortunately)

the Chrono was kinda jacked, was giving me a hair under 2700 with the 93gr load. It stopped working before I could shoot the hotter loads(imagine that, and no I didnt shoot it).

300gr cup point
all measurements same as above
90.2-92gr, the book max for RL22 in the Swift book with a 300gr A frame is 97gr. the cup points are different, so you know that 97 grains might not be possible, but once again limited testing has kept me from getting up there. it shoots 92gr with no pressure signs.

After I use all the RL22, I am gonna try H4350. Some folks think you can get a good velocity for bullet weight and powder load with less percieved recoil.

Thanks a ton for the comebacks - I appreciate it! This is what I'm thinking of doing:

1. Get a new Rem 700 BDL in 300 RUM.
2. Remove the factory barrel.
3. Install 26" Lilja barrel - std contour, 0.825 inches at the muzzle (barrel #7) - now chambered for 375 RUM.
4. Pilar/glass bed it in a new camo fiberglass MacMillan Stock.
5. Put on a Jewell trigger.
6. Get the barrel and action Robar finished.
7. Mount a Leupold matte 3.5x10 Vx-III with B&C reticle.

This gun should be accurate and deadly, but also heavy enough not to be punishing.

BUT, I've heard the Rem 700 actions have trouble feeding 375 RUM cartridges. Is that true?

Regards, AIU

mine feeds pretty reliably, and I have the detachable mag. It also depends too on the shape of bullet. I have no probs feeding either the cup points or spitzers, and of course spitzers feed easier than flats or cups. Depending on what sort of load you develop for that rifle, it swill still beat ya pretty good, even with a 10lb rifle. Everybody's tolerance for recoil is different, I am a little recoil shy. Shooting those 250NF's over 96 grains pegs the fun meter for me after a dozen rounds. But that's me.

Dont forget to try the H4350.

Personally I'd build the .375 RUM on a MRC action.

That's assuming one needs a .375 RUM.

What's a MRC action?

Are MRC actions good?

Mine houses a 404 Jeffery and I'm happy with it.

I called MRC today - I think they have a great product. Are their barrels as good as their actions?

My barrel is also from MRC....I like it too!!!

The velocity gain on paper over .375H&H using equivalent bullet is apporximately 200fps. Assuming equal barrel lengh that's a significant gain. What does this mean in practical terms?
Given variables such as: shot placement, distance, adrenalin levels in NS of specimen,....Perhaps we will never know for sure.
I never owned a Remington rifle, so I don't know how good, or bad they are.

Ditto

Very good.
I purchased a used Remington 700 ADL SS som time ago. The former owner had replaced the originalstock with a H-S presision stock since it kikked like hell with the original stock.
I bought a Nikon Gold Monarch 1.5-6x42 and put i on.
The rifle is not bad too shoot at all, but i take som time too get used too it.
This is my brother shooting it for first time. http://home.online.no/~oerj-j/375rum.cfm

if you are worried about components you could be like rip and do a 375 lapua KABOOM! now that is a good combo
