As you know I have been shooting 200 gr Accubonds in my 300 win. I settled on a load of 76.5 gr of H-1000. This shoots exceptionally wellin my rifle. Two groups last night were under 1/2 MOA. Which is as good as I can shoot. However I chronoed these loads and was just a touch under 2700 fps. Is this fast enough to consider a good reliable load? What do you figure are my distance parameters? Thanks

Rough estimate from my ballistic program shows you 2.1" high at 100 yards, dead on at 200 yards and about 8.5" low at 300 yards.


Hodgdon says that you should be able to get 2883 fps using 79g of H1000 and 2962 fps using 84g of Retumbo.

For the added reciol and weight, I don't see where it is any better than the 30-06. I'd use IMR 7828 SSC and be looking for something in the 3000f/s range. I have never done well with H1000 and haven't used it in over a decade.
Given 1/2 MOA, it is obvious that your rifle will shoot boat tail bullets, so I'd find a new powder and drive on with load development.

chain, I've got a 24" barrel on my 300 Win Mag, and 70 grains of H 4831 gets me right at 2900. RL22 was faster, but not near as consistent. I light em up with a CCI LRM primer, and they're darn consistent.

I'd agree with buckshot, to warrant shooting the 300, I'd work towards another load to push that velocity up a bit,BUT if your shooting the rifle that well, the game will never know the difference--it's always accuracy first for me!

What you got will work but I'd be looking to better the velocity a bit. I'd give a bit on accuracy to do it as well. Even if you can still get MOA and 2900 you're a bit better off but we're splitting hairs here too.

A 200 gr 30 cal at 2700 thats a.5 inch rifle would be ajoy to hunt with and would kill any thing you want to shoot with it.

p dog shooter is right. Just think how long your brass will last too!

According to some ways of thinking a rifle will have "nodes of accuracy" and there may be another node at higher velocity but you would probably be pushing max. In my Mato 300 win mag I'm trying to close in on one at around 2900 fps. I've got loads ready for testing with the 200 gr Accubond and the 200 gr TSX with 72 gr RL22 and 78.7 gr H1000.

on the right is 78.7 gr H1000 @ 2899 fps 10' from muzzle with 200 gr Accubond



#3 on the left is 71.9 gr RL22 @ 2886 fps 10' from muzzle with 200 gr Accubond



I've found max with the 200 gr bullets to be 2950 fps +, so at 2900 I should be OK on brass life.

I think I am handicapped a bit by my barrel length. My barrel is 22". Is there a powder Icould use that would be better in a shorter barrel? I know I shoot 180 Part's at about 3000- 3100 fps. They just don't group as tight. I think I think I will rebarrel next summer.

chain, I'm not sure of a powder that will do you better with the 22" barrel. I would fool around with the seating depth of the partitions, and see if I could get them to group acceptably. I have seen seating depth affect my groups as much as nearly all the other variables, i.e. a few grains change in powder charge, a primer change, or such.

As an alternative, I don't know if you would want to go here, but they offer the AB in .308 @ 150 grains, it would sure pump your velocity up some, and would be sufficient IMO for anything in North America short of the Big Bears.

Good Luck--Don

If I had a 300 with a 22" barrel, I'd be looking at IMR/H4831 with 180s to achieve ~3,000f/s, or thereabout. Even the various 4350s are worth a try.

nosler just released their 165 accubond that would be an option also but the bee''s knee''s would be barnes 165 tripple shock, 1/2 inch groups are great no matter what the speed is,just cause its a 300 win magnum doesn''t matter at all no punn intended, your opinion and final decision is what really matters, i once loaded my 7mm remington mag with 154 spzers doing 2700 fps, told a vet reloader about them and he put them down verbaly cause they were so slow ,short story shorter i desided to hunt with them they grouped into my thumb nail at 100 yds 5 shots, and i shot the bigest whitetail buck of my life with them reloads,soooooooooooooooooooooo go figure.....regards jjmp

I was thinking of working with the 165 accubonds and the 165 triple shox. I just want to get something I can work with this year. I want to get a load to work well enough so I can practice at 300-400 yds prior to heading for MT. I liked the way the 200 gr shot I was disappointed when I chronoed them though. I am shooting some 180's tonight with some IMR 4831. Thanks Guys

well, a 200 grain 30 cal bullet will put a serious hurt on ANYTHING that gets in it's way. i'm not sure but i believe the late Bill Jordan said "speed's fine sonny, but accuracy is final." you could do some more load development with different powders or with higher loads of H1000 the rifle is a shooter and you may find another higher velocity load that equals this level of accuracy. good luck

and 70 grains of H 4831 gets me right at 2900

I'm w/ Fish on that one, H4831 from 70-72 gets me right around 2900+/- w/ 200s and nice accuracy.

Good Luck

Reloader

I have shot a little heavier dose of H 1000 but the accuracy wasn't there. I don't think it was much faster either I didn't chrono it but the POI didn't change vertically the groups just opened up as I increased the dosage. Does that mean I am as fast as I can get with that powder? I would be happy with 2900. I might try RL 22 this weekend. It is hard to lookaway from those tight little groups though.

Chain,

Personally I would be wringing out some more options. As you know from our previous conversations, I drive my 200 grain Accubonds right at 3,000 fps. Granted, I have a 26" tube, but even with a 22" tube I would expect a solid 2,850 with the newer powders we have availabe to us. There are a lot of powders out there that will get you there velocity wise...finding acceptable accuracy, that's another thing

Out of curiosity, what make is your rifle with a 22" barrel? I didn't know they made such an animal.

In case you didn't see my post concerning the Swift Scirocco II's I have been trying to get to shoot, I have exhausted all of the time and resources I am willing to give on them. Yes, there are other combinations I could try, but I'm not willing to give it any more after trying four different powders and a box of 100 bullets.

Help me out by listing the bullet/powder combinations you have already exhausted in relation to the Nosler Accubond in 200 and 180 grain guises.

FWIW, with the abandonment of the Swift Scirocco, and the fact that I would rather shoot a 180 grain bullet, I have begun load work-up with the 180 grain Nosler Accubond. I just loaded up a batch of three shot groups consisting of:

W-W brass - Full length resized
Federal 215M primers
Various charges of Reloder 22
180 grain Nosler Accubond

With all the hype of RL22 on this and other boards, I thought I would give it a whirl. Hopefully I will get a chance to shoot this weekend.

Hi

2700 fps on a 200 gn bullet is absolutley and totally perfect for everything except dangerous game. Dont be swayed by the velocity guys, accuracy always wins.

Mark

My rifle is a savage 110. I had a different barrel but it came back from the gunsmith with this one on it. I got it back in July and just measured it. I feel kind of dumb not noticing it but my stock is somewhat longer( LOP 15") so I guess I just didn't notice. I shot the 180 accubonds well with 80 gr of H 1000 just haven't chronoed them yet. I also don't have any to try. I am working with 180 Part's with the Protected Point and some 180 SGK. I have those on hand. If I don't like what happens in the next 2 weeks I will go back to the 180 Accubonds if I can't make them as accurate as the 200's , I will shoot the 200's. I have been ri9ght around 3000-3100 with some of my 180 loads though. I can live with that if they make a small hole. Thanks

So basically you are shooting a 30-06. If long distance is not on the agenda then you're good to go. Personally (and this is me!) I would find something that breaks 2900 fps. That is why you boughtt a mag right?

Pop You are right. I started with getting something to group well when I chronoed it I was disappointed. That is why I think I am dropping to 180's and or a different powder

Tis true MarkH, but why burn much more powder to create more muzzle blast, recoil and noise to achieve the same thing the good old 30-06 can do. I doubt this is why Chain bought a .300 Winchester MAGNUM.

Chain,

What are you planning on hunting when you come to Montana? As you know, I have a couple of personal experiences with the 200 grain Accubond on antelope, mule deer, and elk and have been totally satisfied. I also have a number of family and close friends that have shot the same animals, with the addition of black bear with the 180 grain Accubond. The result has been the same with the 180's as the 200's I have shot.

I have decided that if I can get a load with the 180's that shoots as well as the 200's I am going to switch to those. There are alot of opinions out there, but I think the 180 grain bullet is a perfect match for the .300 Win Mag.

How many more 200's do have?

By the way, I was getting just under 3,100 fps with the 180 Scirocco and H1000 at 81.0 grains. You might want to try chronographing your 80.0 grain load under Accubonds. You might be pleasantly surprised.

When do you leave for Montana?

I have about 50 left. I am shooting tonight some nosler parts and some SGK's both 180's. I have shot 180 accubonds with 81 gr of H 1000 with good results but I ran out of them. I leave for Montana on 4 Nov. I think this barrel length is killing me I wished I would have known the length before I gotr it back. I just didn't figure someone would put a short barrel like this on a 300 win. I am trying the SGK's tonight after talking to my outfitter, he said that was his bullet of choice. So I thought what the hell I could try them, I imagine they will kill a deer. I can't wait it is my first time out to Mt to hunt deer. I was there awhile ago for a bear hunt. I just need to get this load work done so I can bow hunt here and practice at 300-400 yds, just in case. Thanks

Chain,

I am first and foremost a fan of the bonded, polymer tipped bullets, but then again elk is always on my menu. With that said, if all you are after is mule deer, there aren't too many bad choices in a 180 grain projectile for a .300 Winchester Magnum. If the Sierra Game Kings shoot well for you, they are plenty for any deer that walks. If they don't happen to shoot well for you (I'll be pretty surprised), but if they don't, I would give some serious thought to the 180 grain Nosler Ballistic Tip. In my estimation, this would be an extremely good bullet for the intended purpose. I wish I would have been on the ball enough to ask you what you were hunting, I just assumed elk was on the menu.

I agree, the barrel length isn't optimum for a magnum, but now that it is there I wouldn't let it bother you. If at some point in the future you want to change it, o.k., but for this year and many to come it will be fine. They say you lose approximately 30 feet per second for each inch of barrel. That equates to approximately 120 fps off of a 26" tube and only 60 fps off of a 24" tube. In the past I have been able to safely get 3,150 out of 180 grain bullets. Given the approximate velocity loss, that would still be 3,020 out of a 22" tube.

Obviously this is all conjecture as we don't know all of the variables and we are dealing with theory and approximations, but I point it out to so that you don't think all is lost with a 22"er. Look on the bright side, makes a lot nicer carrying gun

It does carry well enough. I have gotten 180's to go to 3100. I forget the load at the moment. It is deer I am after, muley or whitetail. I went to Manitoba two years ago after whitetail. I hunted with a bow and muzzle loader I came home empty handed, I never even seen a buck. But that is another story. I am really looking forward ot his hunt as I wasn't able to hunt at home much last year due to work travel. How much shooting and hunting could we all do without day jobs. I will probably rebarrel next spring but you're right I am going to make do with it this fall. I guess that isn't that much velocity loss I thought it would be more. I know I can shoot the 180's closer to the max or at the max load more so than the 200's. Thanks

How did the barrel on your 300 Win get to be 22"? It has basically been demagnumized. Yah I know that isn't a real word but it fits.

Rifle went to gunsmith to have action trued up, magazine box lengthened, and bedded. Gunsmith shot rifle couldn't get it to shoot as well as expected. Client ( That's me) is cost conscious and says What do we do now. Gunsmith says we need to rebarrel, Client says, How much? Gunsmith says $XX.00 for a take off savage barrel, he has a bunch of them there, and $XXX.00 for a after market barrel depending on how much Client wants to spend. Client having just returned fron getting married in Vegas i.e. out of money, opted for the cheaper option. Client never gave any thought to barrel coming back less than 24".Client feels like a dumbass now though.

Chain

As long as it is accurate you'll get by. But I was curious. In awhile some money will be available and you can correct the problem. Until then you have a rifle that will still collect some game for you. If the Gun is a Savage you might think about rebarreling it youself. Do a little reading.

Jay That is exactly what I am going to do . I am going to re barrel myself in the spring/late winter. I am just trying to put some meat on the table this fall.

There ya go!

Say a guy gave away a 300 Win Mag barrel over there with a Visa brake on it. Was probably a little heavy for a carry rifle but keep your eyes open. Northlander has some pretty good deals over there I just picked up on a couple of them.

You can pick up a wealth of Savage information over there. The SSS site is also a good place to look. Here!

Where is that at? I don't really care about a little more weight. I would rather have a long range shooter. As alot of people have pointed out I might just as well have an '06 if I can't get some speed out of this. I want to get a carry rifle for here in MI. But that is another project. I am just trying to get this one shooting for my trips out west for deer and elk.

The truth is that no muley in the world can tell the diff between 3100 and 2950 fps with any 300 win mag 165 on up.

Good point Pop, I was going over some calculations last night and if I can get in the high 29's I am content until I re barrel
