375 Remington Ultra Mag

[northernlightsflyer]

I use the the 375  for my hunting here in Alaska. I use factory loads in 300 grain from Remington.

I had this rifle done in the custom shop with modest engraving

After shooting this several times I decided to have it ported ,I took it in to Fairbanks and had a great job done and it took the kick out.

I have a fixed 6 power Burris scope and have it mounted with quick detach mounts.

I have shot Moose  Bears  Caribou and Dahl Sheep with this gun and it is remarkable that with the 300 grain bullet how little meat is damaged even if you make a  Texas  Heart Shot

I do prefer BIG gins and nothing i have ever took with the 375 ultra mag ever made a step they just drop like a 55 Chevy with a trunk full of rocks.

I am hoping that there wil be a alternate to the factory loads from Remington however this don't seem to be a very popular gun here . My local gun shop owner told me I had the only one he ever has seen in Alaska

I will keep this as my primary grocery getter as long as I am able to hunt,I also have a Model 8 Remington in 32 Rem. Cal I use some on Caribou just for the fun of shooting a family heirloom.

Would like to hear from others who use the 375 ultra mag  I do know in Africa I am told now that is the gun of choice for a lot of Hunters

I have a friend who bought one when he found them on sale a few years ago.

It hurts!  It kicks harder than my 458 Win Mag.  It is a sharp kick!

It reminds me of the Weatherby calibers;  i.e. the 338 Win Mag vs the 340 Weatherby (as well as other pairs).  Weatherby used a proprietary (read expensive) cartridge, added an extra pound of powder and gained a couple hundred fps.  And doubled the felt recoil!

I think the 375 that you heard about being the "gun of choice in Africa" is the 375 H&H Mag.  Now there is an old workhorse - recoil is tolerable, affordable ammo can be found in about any store that sells ammo (in Alaska or Africa).

It has been the standard moose and big bear gun around here for many years. 

Back to my friend - he had his 375 RUM ported and it is now bearable to shoot but he can't afford the ammo.  And it seems to be getting harder to find and more expensive every day.  He mentioned seeing it somewhere for $200 a box!

If you own a RUM (in any caliber), my advice is to lay in a cache of brass and a set of reloading dies. 

But you are right about it being a killer, same bullet as the H&H, just a little faster.

Like several of the RUM cartridges, this one is a beltless clone of an existing Weatherby cartridge - in this case the .378 Weatherby Magnum.  It shares that cartridge's reputation for excessive recoil for the performance.    I doubt that the .375RUM is a "gun of choice" for many African hunters, the original Weatherby cartridge certainly isn't after decades to gain a rep.   That said, these are very powerful cartridges which kill very well with good bullets.

The RUM cases are a reloaders dream I load for and shoot both a 300RUM & a 375RUM in almost identical Rem 700 LSS rifles I can load down or load up to get exactly the performance I am looking for.

Right now I am loading my 375RUM with either 260gr Accubonds @ 3000fps or 300gr Sierra's and Partitions down to 2750fps and anything that has been on the recieving end of one of these bullets drops on the spot.

I am not the biggest guy 6'3" 215lbs and other than installing a Kick-Eez magnum recoil pad I have only glass bedded and adjusted the triggers of the rifles.

Due to my interest in this cartridge a buddy of mine bought a 375RUM this last weekend he is a major elk/moose/sheep/grizzly hunter here in BC.

I drew a grizzly draw for this sping and will be using my 375RUM on that hunt my son will be backing me up with either the 300RUM with 200gr A-Frames @ 3150fps or my Marlin 1895GS 45-70 with 550gr Jae-Bok Young Crater's...

My buddy with the new 375RUM will be coming along as well.

Oh yeah we will also be hunting for 6' + black bears...

Not a clone actually.  The .378 was it's own cartridge when it was first developed.  The ultra mags are based on the .404 jeffery cartridge, which outdates the .378 weatherby by over 40 years.  Even the base diameters of the two cartridges differ by .04".

[Lone Star]

The .375 RUM is a performance clone of the .378 Weatherby.  The .378 was based on the .416 Rigby (1911) while the RUM was based on the .404 Jeffery (1909) - two more virtual clones of each other.  What one will do the other will do as well.

Here is the interior grizzly I shot June 1 2008 @ 230 - 250 yards with my Rem 700 LSS 375RUM with 300gr Partitions @ 2750fps mv...

Yes I have my Marlin 45-70 in my hands in the picture, hours after I shot the bear my son and I walked into the thickest possible bush after it so I carried the Marlin loaded with 525gr Beartooth WLNGC's.

The skull has unofficially been scored at 24 1/16" which will put it into the all time Boone & Crockett record book.

I am new here, and the proud new owner of a .375 RUM. I am not recoil shy but my .375 is a whole new level of pain I have never experienced!
