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

+1 I also use 76.0 grs of RL 22 for 3130 fps in a 25" tube!!

Seafire, I wasn't trying to criticize you and apologise if I came off that way,just can't Imagine getting that long of a bullet with that charge in a 300wm case!I have shot 180 Scirrocos and 82grs of H1000, another very accurate combination!

JWP,those are some nice groups! ya need to be careful your gonna wear out them negatives!

If I were you, I would find me a good gun smith. Have him spin that barrel off and re-chamber it. I think you will be happier in the long run. I would not send it back to the factory.
One more thing to think about, if you are going take off your barrel go to the cost of rechambering it, for about $300.00 more, you can buy a new custom barrel.
Just some words for thought.

HD, agreed on all points.

I have an appt. next week to take it to my guy. I don't think i'd pay the money to rechamber, but he's telling me $40 to "clean up" the existing chamber... he suspects a wee little burr at the chamber mouth, and I put a dental pick in there today and indeed, that edge did feel a little ragged.

I plan on rebarreling this withing the next year anyway, BUT, I'd like to shoot the $hit out of this barrel first <g>!! If you know what I mean. Just want it to function. At 300 Win Mag speeds I mean.

Pardon the cussing. We're all adults here on the reloading section, right? :-)

Wish you luck.

Jeff,

Polish the crap out of that barrel with some JB.
Muzzle down flush with the floor careful not to touch the crown and go after it two or three hundred times.

Seat a 180 into the lands in front of 79 to 80 grains of 7828.

I wish you were closer I'd let you borrow a can of it.

I hear that! I've got big cans of things that need sharing too.

There should be a website where people can trade this stuff. Let's see... how about:

ShareYourHazmatMaterials.com

or

YouCan'tLegallyShipThis.com

:-)

Believe me, I am getting close to buying some books and a few tools and just doing this stuff myself! I've worked with metal all my life. "How hard can it be?" (famous last words)

Ackley,

dont' sweat it there fella, didn't take it as a flame at all..

ya asked a valid question and hopefully I gave you a valid answer...

I come on here to share info with fellow shooters, not to butt heads with those that just like to come on line to argue since they don't have someone at home to do so with...

I am not normally a Magnum shooter... so my attitude, if I am going to need a magnum, then I am going to get MAGNUM performance out of it....otherwise I'll use a lighter cartridge..

hence the 220 grain and hence the 2950 fps...it wrings out the maximum punch capable out of a 300 Win Mag....

"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! "

280,
very legit question...after 4 or 5 years of sharing load data with fellow shooters, I have a lot of folks appreciate it, and I have a batch of guys who not only criticize it ( much smaller group) but just flame and flame and flame...

The problem here has been minimal on 24 compared to over at AR..

I guess over time, one starts to get hypersensitive to the flaming when you do stuff, share it for free with fellow shooters, and then get pissed on by a few, but try and get your goat by claiming you are going to hurt or kill someone..

I was raised and believe to try to get along with others, even when they may have a different perspective.. to respect other folks... its this attitude, vs the "F.U" attitude that other folks have..

that and being raised with the old value of " If you don't have something good to say, then don't say anything at all" kind of attitude..

So if my hypersensitivity seems a little too much for a few folks, I do apologize.. it is just not in my make up to tell someone to kiss off when I probably should...

beleive me, it doesn't bother me to spar with anyone, verbally or physically.. but arguing on line is like competing in the "special olympics"... and I am here to share info with fellow shooters, not get bogged down into a pissing contest with someone who hasn't even tried what he is criticizing.. so is clueless yet tries to present himself like he is "the" expert on the subject...

"its hard to soar with eagles when you work with turkeys" .... and some of these boards can get some real turkeys on here...
350 lb armchair ballistics experts...we all know the type..

cheers

RL-22 with bullets 165 & > is better than either, IME.

H4350 & RL-19 with 150's.

Just getting starting on loading & shooting the 300 Win Mag. Good string, good info, & enjoyed reading the postings.
Good info, bases on experience, is getting to darn rare. I appreciate your sharing. Thanks guys.

I got a chance to shoot the rifle with H1000 today...

78 grains was giving me an average of 2960 fps behind a 180-gn Ballistic Tip. I didn't hit a "bughole" load, but everything was shooting right at MOA at 100 yards. So there's hope there. I'll mess with OAL and add a grain or two of powder, see what happens.

As JWP and others said, the stuff was very consistant shot to shot as far as velocity. I like that! The extreme spread was 26 fps across 20 rounds.

I seem to have somewhat fixed my chamber problem, or at least it's really obvious now what it is. I hit the chamber vigorously with a brass brush a couple times. Now, it's much less sticky- though still a little so- and I can tell what the problem is now. It's a burr on the outside mouth of the chamber. I can tell this easily now, because apparantly I removed about 75% of it! Now there's just one, really obvious spot leaving shiny scratch/drag marks when I extract.

This is a subtle burr. I can't feel it even with a dental tool- one of those ones they use to pick at your teeth when they clean them. But I can sure see the marks it's leaving on the brass!

Anyway I'll be buying a can of H4831SC next, unless I find a bughole load with the H1000, which would be cool too. I liked H1000 so far. Seemed very consistant.

MM- I'll have to try RL22 again. I tried it the first day shooting the rifle, when the chamber was SCARY sticky... so it didn't get a good test as I was unsettled by what I was seeing, to say the least, as far as rifle misbehavior! I do remember that I was getting decent accuracy and it was right about 2960 fps or so 3 or 4 grains under max.

Heres some results I've had with my Win 70 Classic Stainless with factory 26in barrel. I've pretty much settled on RL 22 and 180 TSX as my hunting load in this rifle but have had great results with the Accubond.
