Hi guys. Finally got around to cooking up some loads for the 375 rum today. Went to the range this morning. Settling in on a 300 gn nosler partition over 94 gn of h4831. Easy load to shoot. I need to chrono yet. I loaded up to 98 but groups got bigger with every grain increase. 94 shoots well under moa. At 50 yds, all in a hole. 100 is around .5-.6. Cant be more pleased at this point. Just wanted to throw out an update. thanks

I'll take your word for it. That load is about 7gn more than the load I use on the 375R. While I don't think the Ruger is hard to shoot I have never shot anything higher in the recoil department. I've shot some stout 45-70 loads but the Ruger certainly surpasses that. Now that you have your load are you planning a hunt somewhere?

Let me say that the recoil on that load is very tolerable. When you go full load, it becomes pretty hard on the shoulder. I will be using it off and on for deer season this year. I have to make sure I put the deer down, you know how dangerous they can be.

What kind of velocity are you getting? I have a REM 798 that I re-chambered from .375 H&H to .375 Wby and I can get 2,800 with a 300 gr bullet easily which is pretty similar to what the RUM should do.

What kind of rifle are you shooting and how much does it weigh? I have a Rem XCR II in 375 Weatherby that weighs 7 1/2 lbs unloaded with it's Leupold 2-7x scope. Shooting 375 H&H full power loads it's a breeze, shooting factory 375 Weatherby 300g Partitions it's a tad snappy...

Not sure yet. Didnt take the chrono. Was just looking for accuaracy this time. I'll get back out and get some #'s soon.

Not sure if you're asking me but I'm shooting an xcr with a b&c medalist bedded. Warne bases and rings and a zeiss scope. Guessing 8.5lbs. Full house loads are a bit uncomfortable. These loads at 94 gn are very tolerable.

I was and thanks gunchamp. My 375 Weatherby full house loads should kick less than your 375 RUM. They're not bad at all in my XCR II, the 375 H&H rounds are pure pussycat.

I have used my 375 RUM in Africa several times . 300 grain TSX with 100 gr 7828 is just above 2860 fps and is very accurate.95 grains of h 4831 with 300 north forks is a hammer. I have had poor luck with 300 nosler partitions on big game buff etc. I am sure they will be great on plains game . It is a great round and I don't find recoil that bad and I have no break. My gun is AHR custom made on CZ action.

After running a good many rounds through the RUM, the 375 ruger and H&H do feel pretty mild. I do have a muzzle brake on mine but I never would use it in the woods. I rarely use it at the range. Full bore load development got pretty nasty, thats when I screwed on the brake. I'm glad the 94 load shot so well, very shootable for me.
