moki, With 300gr partitions I use 95gr. reloader 19 and get 2800fps. Actually i use 94-95gr with all my 300gr bullets. Wtih Sierra Gamekings and 95gr have shot .4inch 3 shot group at 200yrds. No I probably could not repeat it but at least I know i've got a good load worked up.

John T,



"We always welcome new members to keep us company. Heck there ain't many of us."



Well I hope that invite extends to me also. I'm in the process of putting together a 375 RUM and a 7mm RUM. Just finished my 300 RUM and am wringing it out. I have my bbl for my 338 RUM. But from what I see on paper, it won't get too far away from the 340 WBY. I'm a little sceptical about duplicating the horsepower.

Olcrip,

Most definitely you will be most welcome. You have heard our host's Saeed's opinion on the calibre & since you are bringing little brother (.338),little sister (.300) & baby sister (7mm) along - lets make it a family affair.

Most likely those that decide on a 375RUM will already have a H&H or even a few H&H's . The old question arises "How much vanilla ice cream can you take? ".

All the power you could ever want for hunting big game, relatively affordable brass, lots of bullet choice - get to it & join the club.Look forward to welcoming you to the club.

RIP - good to see you posting. Knew this thread would get you going. Just working on my 404J now. Kicks the living daylights out of me. Currently its open sighted with a very straight stock as you'll see from the pics I sent you. But it is way too light at 8lb 4oz(why didn't I figure this out sooner ). Am going to send it in to the fat farm & put some recoil reducers on. Have not chronographed my handloads but they should be mild, 77gr of H4350/AR 2209 with 400gr Woodleigh. Even shooting on sticks its pretty savage. If I shoot this one more I figure the 375RUM will be a pussycat.

Regards
JohnT

olcrip, the 338rum case is shorter than the other ones. But the 375rum is right on the heels of the 378wby.

235 Speer/95g IMR4350 gives 3,000fps from my 26". It's a mild load that should be all I need for deer or practice. Accurate and velocity deviation is low. I only checked 3 shots, within 10 fps.

the only load I've tried in my rifle is 95g IMR4350 with 235Speer. I chrono'd it at 3,000. I'm going to use it for deer hunting this year. It's a lite load, but still shoots flat.

My wife gave me the ok to purchase a new rifle last night. I have a Rem 700 BDL s/s 300RUM and would like to add a Rem 700 LSS 375RUM to it. Does anyone have any thoughts or experience with this rifle/cartridge? Any suggestions would be great.
Thanks,
Cam

hyena, I used to shoot the H&H and the 375 WBY. I liked them real well but the 375 RUM sounds so intriguing that I can't pass it up.

Chronoed my 300RUM last Sunday and was ammazed that I got 3450 fps with 180gr Power Points. No signs of preasure and real tight 3 shot group. Haven't had time to measure it yet but on the target it looks to be somewhere around 1/2 to 5/8 inch. It would have brought home the venison.

The rifle will be the same as you already have except for the cream and grey laminated stock.

As to the 375 RUM itself I don't think you could have a better endorsement than the fact that is a factory version of Saeeds 375/404. Saeed has a pair of 375/404s and he seems to have settled on the 375/404 for his shooting needs.

Mike

It's one I've been wanting! Go get it - it should do everything needed for heavy game, even at extended ranges. Ballistics are pretty impressive on paper, but I have not shot one personally yet. maxman

Chronoed my 300RUM last Sunday and was ammazed that I got 3450 fps with 180gr Power Points.

Was that across a Chrony?

Mike

Jeez! What powder and charge weight? I do good to get 3250, and I have the exact same rifle as you.

Mike 375, that was over a Pro Chrono. 3 shot average was 3453 fps..............Olcrip

I would like to know as well because I'm looking for a better load for my 300 RUM. Was using 95grs Reloder 25 with 180gr Scirroco's but started getting hard extractions after shooting about 80 rounds out of my Rem 700 BDL s/s synthetic stocked rifle. I was talking to Rick at Seirra Bulletsmith's ext. #9 about this and he suggested that I try cleaning the throat of the barrel better. I haven't had a chance to try that yet.
Cam

Moki, the load I used for that velocity was as follows:
Powder: 96 gr H1000
Primer: Fed 215
Bullet: 180 gr Win. Power Point.
Oal: 3.582

I'm sorry I got the wrong figures on the velocity.
Velocity for the 3 shot group was
3426
3385
3426
Avg: 3412 fps. 41 fps spread.
3 shot group measures .512
This is astonishing to me and I am really tickled. I will go out again and see if I can repeat those same figures next weekend.....Olcrip

Hmmm... I get 3150-3170 with 180 gr. Nos BTs and 92 gr. of H-1000, so 96 won't put me anywhere near 3400. Too bad; I'd love to have a "fast" rifle.

I get 3200 with 200 grain bullets and retumbo in my 300 ultra.

Gentlemen,

Different lots of the same powder can have quite an effect on the velocity.

The only choice any of us has is to try to work up a load and see how much powder our particular rifle will tolerate without showing signs of high pressure.

We get some European made rifles here that show signs of excessive pressure with starting loads when using some powders.

Moki,

Great calibre. Really does make the .375 bore more of an all rounder if that is possible. Mine is a 375H&H M70 stainless that I had rechambered. Put a Leupold Vari X III 1.75 - 6 x 32 scope on it, would have preferred the 2.5-8 Leupold but due to the location of the mounting holes in the M70 long action that was not possible (tube too short).

Performance - as Mike 375 says have a look at what Saeed has done with his (everything falls dead! But have u seen how good this guy shoots!!). As to sales I don't think they are selling many but this is one of the most efficient RUM's IMHO.

Recoil is pretty stiff. That's the only downside. Recoil is very subjective but in my own case it was much more than I expected for the extra 200fps or so above H&H velocities it provided. I can shoot the 375H&H no problems but 3 shots with this one off the bench is enough. I am still coming to terms with it. So make sure the overall rig weighs at least 9.5 lbs. Mine is 9lb 13oz & that is none too heavy.

Have a search at posts by "RIP" as well. He's had his for a while based on a CZ550 action. That may be the better way to go as they are a heavier action & have a big magazine. Get one of those & rechamber & you have a fine DGR with a bit of gunsmithing. (Mine fits 3 but only just.) The .375 is the minimum legal(whatever that means) calibre for dangerous game in all of Africa & many here consider that a DGR should have controlled round feed & that big Mauser style claw ectractor. But if you are set on a Rem 700 that is fine as well.

Hope you do get one & join the club. We always welcome new members to keep us company. Heck there ain't many of us.

My buddy got one. It is a great rifle. It kicks like a SOB but you get what you pays for and there ain't no free lunch. It will kill very nicely. You will like it. It may take a bit of time to get used to, but when you get in amongst the big and uglies you want a gun that kicks really hard. Been there and done that. I want one that kicks my teeth in when there are big black bodies, snorting and grunting, at short range in the long grass. Saeed does nice work with his. I hope you do as well and get as much enjoyment as he has gotten out of his wildcat. Good hunting. "D"

Hey John,
That one whitetail buck I shot, with the CZ 550 .375 RUM, at 50 yards, from a tripod stand in the Kentucky creek bottoms ... that deer had a big hole straight through its vitals (chest) ... it staggered about 50 feet and laid down and died with minimal meat damage, just a few of the ribs messed up.

I like the idea of a Winchester M70 or a CZ 550 for that cartridge. I still have about a hundred rounds of the factory 300 grain Swifts before I have to reload for it.

Cheers!

Allow me to cast a dissenting vote. For the amount of powder invested and conmesurate increase in muzzle blast and recoil, the difference between it and the "regular" 375 H&H is not that dramatic. Yes it does shoot flatter, but normally the types of animals taken with a 375 aren't shot at exceedingly long ranges. One can make 350 yard shots with the H&H without too much trouble.

It would be interesting to see how sales of this rifle are coming along. Given Remington's propensity to drop calibers at a whim, I'd be careful. Another option is the 375 Weatherby. Lots of them out there in Model 70 actions which would be my choice. It was also never very popular, but it has been around since the 1950s AND you can shoot regular 375 H&H ammo out of said rifle if you had to. jorge

Saeed-

First of all, I want to thank you for your sponsorship and everything that you do for this forum. I come to this forum daily and as a hunter and handloader I extend to you my greatest gratitude.

Secondly, I was looking at your video clips of your African adventures and admiring your .375/.404 Jeffrey a.k.a .375 RUM and was wondering if you would tell us more about your rifle such as type of action barrel, etc. And from the videos you can shoot it very well, I might add.

Lastly, how would you compare the recoil of a .404 Jeffrey versus the .375/404 or .375 RUM?

Thanks in advance.

What Jorge said (below)....

First, my .375 H&H has all the recoil that I want to deal with when I'm shooting prone or an improvised field position. However, if you have a cast-iron shoulder that may not be a concern for you.

I would think about the availability of ammo, but this is more of a concern if you make it to Africa where .375 H&H is common and RUM's not so. Ammo does get lost in transit sometimes, and you can bet 375 RUM won't be available but that .375 H&H (and .458 Win mag) will likely be.

Good luck with whatever you decide on!

Absolutely, positively, the very best cartridge for hunting any animal that walks this earth!

That is why I invented it!

I can shoot it standing, sitting, prone, and hanging upside down from a tree, and I am only 130 pounds soaking wet.

You have made the perfect decision, you will be amazed at its killing power. No other caliber can come close!

Saeed:

If you're going to comment on a cartridge positively, you should at least try to show a little enthusiasm for it.

I did not want to be seen as being over enthusiastic about something as simple as a wildcat I have designed myself

At least I resisted the urge to tell the story of a zebra I killed with this one without actually hitting him!

It is true, he was facing us, and dropped in his tracks at the shot. We could not find any entry hole for the bullet. But, it somehow was found in his rear leg!!??

We think it bounced off a boabab tree about half a mile behind him and slightly to the left

Saeed,

Love your enthusiasm.

Just curious as to what velocities you are loading your 270s, 300s etc. to?

Have you or anyone else tried the 260gr. Accubond yet?

Thanks

Gentlemen,



I have only 300 grain bullets for my hunting in this rifle. For a number of years I have used the Barnes 300 grain X bullets, and since last year, I have used our own lathe turned Walterhog bullets.



I have tried several velocities, ranging from around 2600 to about 2900 fps. I found those of about 2700-2750 work very well.



This year we tried a slightly faster load, at 2790. You can see photos of this hunt as well as photos of the bullets we recovered this year on Hunting report 2004



Both rifles that I have are built on the Dakota 76 action. One has a 23 1/5 inch Shilen barrel, and one has a Dan Lilja 26 inch barrel.



The one with teh shorter barrel had a muzzle brake, which we have removed this year.



I would imagine the recoil of these 3 would probably be very similar.



I have found felt recoil is a reflection of the stock design, rather than the cartridge.



For instance, I have shot some rifles in 375 H&H which I thought kicked harder than my own 375/404. Which of could should not be the case.



Both rifles I have weigh about 9 pounds with scope, and 3 rounds of ammo.



A well fitting stock sems to
