+1 H1000 seems to be one of the better .300 RUM powders. 4350 is just too fast gor that big magnum
There is nothing wrong with 4350 .......... it's an outstanding powder!
But it all comes down to what you want out of your RUM.
If you only want 300 Win Mag performance ........ use the 4350.
But if you want to run it like a RUM ......... you need a slower powder. Much slower.
I don't have a RUM up and running but just recently bought a barrel in the 300 and will be thinking about trying it ........... I have a lot of projects stacked up!
I also have been loading since I was 19 and now am in my middle upper "50's".
This 300 RUM thing must be like the gold chains and slicked up hair and go chase them blonde twenty somethings around?
Just kidding ...... well sort of! I was not so impressed with the reported recoil of this cartridge but what swung me over was it's seeming adaptability to reasonable downloading ...........
It seems it can wear a fair number of hats .........
But give up on the light bullets!
Best regards

I plan to give the 208 Amax a try as soon as I can find some. I'm not stuck on any one bullet though, just whatever my rifle happens to like the best of the 200 grain and up crowd.
Yup! Yer right about the Blondes and the gold chains..It must be apart of our bucket list!!..I bought 1 for mainly field hunting. I live on the Eastern Shore of Va. so the average in the woods shot is 0 to 200 yards but we do get 300 to 500 yard field shots and I'm getting to old to be dragging and ripping through the woods tracking blood to find deer so like I think Jud said on here, looking for bang flop shots!..I own too many guns so to keep things easy and not have 17 diffrent kinds of powder laying around i use the 4350 because it has worked good for me in all my guns and it is so versatile, but i also didn't buy this 300rum and spend all the money i did on the gun to not get full throttle out of this cannon either. So far every conversation i've had about this topic the powder H1000 and 200gr bullets has come up so there has got to be something to that combination. I understand everybody is gonna have there own opinion but everyones opinion is basically H1000 and 200 grain bullets to get started I'm gonna use what i have until I can get the H1000 and hoping to find some 200 gr accubonds to put the icing on the cake...Thanks Three 44's

Yea there is so many bullets AND powders to choose from out there. And for me to put my blinders on and use 1 type powder is not keeping a open mind to improvement. So I'm like you , to me every gun is different so I should try different combo's to find that sweet spot for the gun...
thanks Nimrod

I agree with you that using one powder in everything is nice. Myself, I use IMR 4831 in my .270 Winchester and going to use it in my .308 Norma. I would really like to shoot it in my .243 Winchester but it seems too slow unless I shoot a 100+ grainer out of it. I use IMR 4350 with my 87gr V-MAXs in the .243 but would love to see 4831 work just to have one powder for all of my main rifles. Whenever I decide what my next build will be, I will definitely consider my caliber choice so I can use IMR 4831 in it and get top level performance. Reality is though, there is no one go to powder that will deliver best of everything in any given cartridge, the faster I accept this, the more options that open up for me. gun)

I shoot a lot of IMR 4350 myself and I really like it. When I started dabbling in long range I started branching out a little in my powder selection. With the appetite the RUM has for powder I'm really hoping I can get WC867 to work well in it, I've got 16 pounds to burn up.
RETUMBO is a great powder for the .300 RUM, so get some if you find it.
Yup thats what I'm talking about!! But got to keep open mind in order to keep improving and learning to better myself...I've learned a lot from this website in the few months I've been on here. We all know attention to detail = accuracy and my long distance V.S. ya'll's long distance ain't the same...What 500 yard is to me = 1000 yards to a lot of these guys on here so the way I see it I can learn a lot from those 1000 yard + guys and take their word of experience as a opportunity to skip over that part of trial and error..This is a cool website and appreciate the time and help that everyone gives ..
Thanks

OK, I've learned that heavier bullets will shoot further then lighter bullets and why that's so but there is such a thing of going to heavy...and i Didn't have a clue about bullet BC but now I do ..it's how the bullet slices through the air.... So now i got to ask about powders and why some powders burn fast and others burn slow. And how do you know what guns likes fast burning powders and why and the same with slow and why?...I know this ain't a easy question but ya'll have gotten through this peanut butter head twice so i figured i would go for #3...Thanks for your time and help!

Well you have learned fast sir! Now powders... these took awhile, for me atleast, to understand. It takes a lot of studying burn charts, loading manuals, and experience to master this. I'm no expert about this subject but I understand a good bit of it. Smaller calibers such as .224s like faster powders ranging from IMR 4198 for the .222 Remington to IMR 4064 in the big powder burners like .220 Swifts. Big Magnums require some of the slowest propellents such as H1000, RETUMBO, IMR 7828, and H870, the lists goes on but you get what I saying. In the middle of this comes medium sized cartridges such as. .270s, .280s, '06s, and other traditional deer hunting rounds. This is where 4350, 4831, and 4064 work the best. Now low capacity big calibers like .30-30, .308 WIN, and cartridges based off the .308 Winchester like IMR 3031, 4895, and sometimes slower powders for the bigger medium capacity rounds when using heavy bullets. Barrel lengths, bullet weights, and personal goals for a given cartridge also has an effect on which powder to use. This is a brief explanation but I hope this information helps.
The relative powder speed a cartridge requires will depend on the case capacity compared to the bore size and the bullet weight often further adjusts what burn speed you need.
A small case relative to a given bore size needs faster powder and a LARGE one like the RUM generally needs a slow powder for top speed without creating excess pressure.
A heavy bullet for a given bore size usually needs a slower powder than a light weight bullet for that bore diameter and a particular cartridge.
A .22 hornet will need faster powder than a .222 Rem. As close as the .223 and .222 are, you can even see a difference in powder preferences between them.
A .22-250 will require slower powders then either of those and a .220 swift will usually need just a tick slower than a .22-250.
This goes on and on up the cartridge ladder.
Now as you reach the upper range of cartidges ........... say a .375 H&H ........ you find it needs faster powders than one might think. It's case capacity is not as large relative to bore size. The .378 WBY is much larger and still uses relatively slow powders.
A .458 Win mag will use powders even faster than the .375 H&H.
There is a reason there are so many powders and it's not just to sell more powder, though good ole competition does play a role.
And the thought occured to me: I would not rule out your 7mm Rem mag. You mentioned 500 yds ......... you already have enough gun for that range. A change up in optics and range finding would likely bridge you issues with that range. So if I were in your shoes, I'd keep that rifle oiled up. Don't let go of that one, she's treated you good for many years ........ she's got several more in her!!
I know my regular "7's" are not going anywhere. Longer bore life and inexpensive brass is too good to pass up for every day shooting!

No, you can't go to heavy in the 300 RUM. IMO, the heavier the better in the RUM. That said Woodliegh makes a 240 gr 308 bullet but it is not a high BC bullet. Great for short to mid range hunting in the RUM. For long range, the most efficient RUM bullet would be the 230 Hybrid and the best powder for it is RL33. You could use Retumbo with the 230 Hybrid but it is a little on the fast side for it. H1000 is a little faster than Retumbo and would leave you with a lot of empty cases space, so I would say go with Retumbo or slower with RL33 being your best bet.
Oh yeah, I've been shooting a 300 RUM for a few years and have tried a lot of bullet and powder combinations and so far the 230 Hybrid and RL33 are the best.
