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

Gonna try one or the other next. Is one a clear winner? Speeds look similar in the books; accuracy is paramount for me though.

4831SC

That's right, I meant to ask about that. What's the diff? I mean I know it's "Short Cut" or whatever, but what's that do? Better metering?

with bullet weight over 180, then H 1000 is worthwhile...

especially with 200 and 220 grain bullets...

my load in my 300 mag, is 83 grains of H1000 with a 220 grain bullet, with an MV of about 2950 to 2975, using a large rifle primer...

it is accurate as hell, flat shooting, and hits like a hammer...

and this is out of a Winchester Mag not a Weatherby...

load might be hot by the books, but a cartridge can take this load 5 plus loadings and still yield a tight primer pocket in my Browning A Bolt...

Same powder and same loading data. As you said, better metering.

Seafire, for now I am loading 180-gn ballistic tips. I have a load with RL19 that shoots great at 2950 fps, but I get a high velocity spread that really shows up at long ranges.

I'll be messing with 200's later this summer, but for now I'm sticking with the cheap, easy to get 180- NBT.

I should have mentioned bullet weight. So, using 180's is one better than the other?

Jeff,

I think the ballistic tips are not the bullet to use in the Mags.. it blows up too easily at close range and high velocity..

I love BTips, but use them at 2700 fps or under MV.. in about any caliber I shoot them in, with the exception of varmint cals.. and then sometimes even then, depending on the quarry...

I like RL 19, but I found H 1000 gave me much more consistent accuracy and MV with much less Std Deviation..

Seafire, agree on the BT's. These are just for target shooting at this point. This rifle is mostly just for long range screwing around.

You are the second person to report minimal SD with H1000...

H-4831 wil give a little mors velocity with 180 grain bullets and it is a good powder to be sure.
I have switched to H-1000 in my 300 Win mag because it gives me a 5 FPS Extreme spread and for a long range load will give less vertical disspersion because of the lower extreme spread. I will give up a little velocity for that advantage. If one is not shooting past 500 or so yards then it is a moot point.
My load is the 180 TSX or Accubond over 81 grains of H-1000 in Win Cases, lit by a Federl 215M.

How well does H1000 meter, I have never used it?

Don't sell them 180 grain B/T's short, they are a fine bullet.

You can take them up to 3100 fps with no problems. "from my experience" I have put a few Elk in the freezer due to this bullet. The newer version of this bullet are much better than the older ones.

I run H-4831sc for this load in my 300 Win.

A few of my friends use this bullet as well.
Good luck

I'll be surprised if I can see anything near that kind of speed from them... my sendero seems to have a balky chamber, or something. Things get very odd in a bad way long before I get anywhere near book max's or book speeds for that matter. It's pissin' me off. I guess I was due for a funky rifle as my last few factory guns have been gems.

But I'm interested in trying to get some good speed! :-) Hence the new powder. I think I'll try them both.

The H-1000 meters just as easy as H-4831sc. This is the powder I use in my 300 Win . when I shoot Swift Sciroccos.<180 gr.>
Hope this helps.

Never used H1000 in the 300 Winnie. H4831, R-19, and R-22 are IME. If 200s are on the menu, then H1000 should be considered. 165s-180s, then H4831 would be the one Id try first before H1000.

7828 smokes 180's and 200's out real fast.

Bought a can a H1000. Since the idea for this rifle is to hit stuff far away, rather than punch little groups up close... I liked the idea of the small variation in velocity.

We'll see what happens, will report. I'll be buying a can of H4831 soon too.

Imr4831 and a 180 gr Accubond has worked really well for me,,,

Seafire,how do you get that much powder and bullet in the case?82.0 grs and a 180 is pretty compressed!what brass are you using?

Ackley:

Do you really use large rifle primers in your winny? How have they worked for you-seems to work great lookin at your targets.

83 grains of H 1000 is 9 grains more than Hornady's maximum in .300 Winchester, and 2 grains more than Nosler used with 220 grain bullets in the .300 WEATHERBY!
