Home Forums Reloading Big Game Rifles H4831 vs. H1000 for 300 Win Mag

How about 300 yards with 180s and H-1000






425 Yards with H-1000

Ditto, or try RL-22. Have had excellent accuracy results and velocity is very good.

my source for H 1000 data is evidently in an older reload manual I have... the amount was 80 grains I believe...

Checking Steve Riccardelli's site, the load for a 200 grain bullet in the 300 Win Mag is 80 grains...with a large rifle primer you are looking at less pressure than with a mag primer..
so I used that and worked up to 80 grains with a 220 grain bullet, and had no pressure signs.. from there I worked up to the 83 grains.. this is a compressed load in this case..this is 5 grains over what is listed for the 220 grain bullet max.. which is 78 grains..

It is fairly commonly admitted that the 300 Win is not loaded to its full potential and even reload manuals are light on the full pressure the round is rated for..

Someone ran quickload for me on this quite a while ago, like 4 years ago, but came back that the pressure was below the SAAMI max for the cartridge.. I forget what the exact numbers were..

however, I also do my own personal test for high pressure, that is pretty simple if not very scientific...

if I can load a case 5 times, and the 6th time the primer still goes in nice and tight, I call it good..

well this load allows me to reload those cases over 5 times..
alot of guys I know who load 300 Win Mags, tell me they get about 3 reloads out of a case...

so therefore, for my own personal use, I call it good.. anyone else, work up.. it is a compressed load...but I was using the 300 Weatherby as a upper end point of reference, as I frequently do for this..

H 1000 is also slower than 7828....

funny, I get flamed by one crowd for using fast powders in cartridges for reduced velocity and reduced recoil loads.. then I get flamed at time by others by complaining my loads exceed what they found in some manual...

goes to show, some of us work with our rifles and find out what we feel is safe.. those that disagree with it, criticize it... so don't use it if you are from that school..

but each rifle is an entity onto itself.. and I have worked up loads, and then when I find it safe in my rifle, I compare it to what I find in manuals.. sometimes it is lower than their listed max, and other times it can be faster, and use more powder..

some people experiment with handloading, and some are afraid to deviate 1/2 of a grain of slow powder even, in a large case, from what is listed in some manual...

I don't criticize them, and think they should consider the same in return..

this wasn't aimed at Albertan above.. he posted his response with respect... but as soon as one person questions a load compared to a manual.. half a dozen come out of the woodwork...and I am heading the usual critique off at the pass..

Seafire. Nobody here flamed or criticized. And yes I realize you noted that below, but you seem overly sensitive to even being questioned.



On this, you and I agree 100%




Why are you so sensitve to being questioned or even critisized? Take it for what it's worth, which is often from those like you noted above, those that think whatever is written on the page in the book applies to every rifle made...which is worth exactly next to nothing!

I prefer H4831 for accuracy.

I'm sort of leary of H1000 as I purchased a hot lot and couldn't get anywhere near published data under 180s w/o pressure signs.

3,000 fps with a 200 grainer is impressive.

The 270 Win will get 3,000 fps with 150's using H1000 also, oddly enough.

+1-- hard to beat with 180's

From my .325 WSM, with a slightly larger bore, I can run 180's to near 3100 fps, and 200's at 2950 fps. These are max loads.

With this particular 300 Win Mag, I'll be shocked if I can get 180's above 3000 fps, from what I've seen. Kind of depressing <g>.

On the other hand accuracy is paramount for my particular application, not velocity.

Have any of you ever had a sticky chamber but with primers still staying round?

No, I have not. Sounds like you got a slow 300 there, bummer.

I have two loads that are safe in my rifle. One uses 80.5 grains of H1000 under a Nosler 200 grain Accubond for an average velocity of 3,035 fps. The other load I have utilizes Reloder 22 under a Nosler 180 grain Accubond for an average velocity of 3,162 fps. I have settled on the 180 grain load due to the accuracy it achieves...although the 200's were m.o.a.

300 Winnie, how much RL22?

With RL22, I was getting 2940 fps with 180's- with the abovementioned sticky chamber. So no way I was gonna add more. IIRC it was with 73 grains but that's from memory.

Funny thing... in a brutal way... is that I have a very FAST 30-06 that will push 180's to 2840.. so I've gained the big 100 fps here. :-(

Just have to really love those 06's

I guess that's the "glass half full" interpretation! :-)

I shoot the same exact load in my Christensen with the same results!

Jeff O,

I use 76.0 grains of RL22 in my load with 180 grain Accubonds.

I wish I would have tried RL22 along time before I did.

To put it in perspective, 73 grains of the stuff, with a 180 BT, stuck a case in my chamber so bad I had to tap it out with a cleaning rod!

I think I have a FUBAR rifle.

Jeff-one of the tubes on my old 700 was a 23" Krieger in 300 Win and then I later had it punched to Wby for giggles.

Bottom line I used H1000 and either 165 Sierra HPBT's and or 200 Sierra's or 200 Nozlers. 4 me and in that tube it worked out incredibly well and no doubt I'd give it a go.

And as SU mentioned 7828 is another very good one (I find more and more uses for that powder all the time).

R22 is the other one I'd take a look at as well.

All of these normally give me the same kind of accuracy as one of the 4350's/4831's and yet they also give me generally about another 100 fps.

Good luck to ya

Back around '92 or so when I was just starting to reload I started out on a 300 WM. I was shooting Nosler 165 gr. BT's with 83 grs. of H-1000. Real accurate and a velocity IIRC of about 3170 FPS.....give or take!

I also tried the Sierra 200 gr. Gameking and was just shy of 3000 FPS.

That was enough for me. Then............and more so now...........I won't buy a pound of powder to gain 100 FPS!!!

Same as then I don't know anyone that is into this as much as me that I feel right asking for a few ounces.

I have a Ruger No.1 in 300 WM that I will get to reloading for and the Nosler 165 BT is what I will start with!!!

Those were the days.........powder was about $12 a pound and bullets were much cheaper!!!

I got 3150 with 74grs R-19, and 76grs R-22 in a 24" bbl. Tried some 200 Patitions with various doses of H4831, R-22, and R-25 all around 2980, but none gave acceptable accuracy. No pressure signs at all.

hunter,yes I use Fed 210M's in a few loads in one of my 300WM's but only with certain powders,In my experience RL 22 needs the 215M's to get tight little clusters,you will hear folks say you need a mag primer in cold weather but I have used them in Northern Montana -10 degrees and they light just fine,some times they really help tighten up a load! Good luck!
