I was woundering has anyone personally loaded this with a 120 gr. sierra. I usually load RL-15 at 42 grs. but I am always trying something new.

i tried it years ago just because i had some laying round when i first started to develope load for my .260. if did not show any signs of accuracy. i developed a super accurate load with varget and have stuck with it.

I tried H380, H414 & W760 in my .260ai, but find them a bit dirtier than say VV150, Varget or RL15. Give the med. burners a try in your .260 w/ 120gr bullets. I like H4350, RL19, IMR4831. Very uniform & max. vel. for that bullet weight, a drop tube helps.

H-414 From 40.0 grains to 45.5 grains
Remington 9-1/2 Primer

W-760 From 39.0 grains to 45.0 grains
Remington 9-1/2 Primer

The W-760 was much more impressive.

I had good luck with H414 and 120 grain speer hot cores in my .260. I used CCI 200 primers.

Now, I can't find the speer bullets anywhere. I bought the last box from a small shop (their last box), and every one is out of stock. I'm going to try 120g BTs next.

WIth 140 grain sierras the H414 didn't do as well as H4350.

43.6 gr 760 w/120 gr sierra works well in my kimber

Vines: take a look at Ramshot Hunter. It is a very dense ball powderfrom Belgium that rivals extruded powders in its ability to work well over a wide range of ambient temperatures. It is also very clean burning. Burn rate is right ahead of R-19 and there is some very good data for the .260 Remington @ http://www.ramshot.com Should give you better performance than H 414 or 760!

Interesting.....H-414 and Win 760 are the very same powder.

If you check a load manual that gives pressure data you'll find that at identical charges from the same barrel, 414 and 760 give different pressures. They both come from Primex and they are similarly made from the same base chemistry, but I don't believe you can call them Identical. Same applies to HP-38 and W-231, W296 and H-110, 748 and 322. The only powder that Hodgdon currently sells that they claim is identical to a Winchester counterpart are HS-6 and W-540. Ramshot Silhoutte is the same powder formerly sold as WAP by Winchester before they dropped it and Ramshot subsequently picked it up. Load data is identical and Ramshot uses the data originally provided by Winchester.

Not tryin' to nitpick, but I see these comments all the time and I have seen too much data to believe that they are identical. If they were, data would be identical when generated from the same source and equipment. If you believe that load data is intentionally kept different between the comparative powders, that would suggest that the testing labs that generate the data are playing along with Hodgdon and Winchester marketing and providing false data, along with any burn rate chart you happen to look at, where they should be listed in back-to-back order if they were truly identical.

KLN357,THE same 10 pound keg. from the company that makes the powder has H-414 and W760 stamped on the side. if you see a differenc in pressure it is because they had different LOT NUMBERS. and theres not that much different in the pressuer.

Vines: Are saying that you bought a 10 lb. keg that said both H 414 and W 760 on that same keg?

Powder charges at the same pressure cut-off are different enough to look like more than lot variation, unless QC is that poor at Primex, in which event I would use neither.

I know a lot of the Hodgdon and Winchesterpowders come from the same base powder. This doesn't mean they are the same finished product. You will also find Scot 4351 sitting in between them on the burn rate chart, so does lot variation account for that?

Layne Simpson did an article on Primex several years ago in Shooting Times, and in it he stated that Win. and Hod. spec their powders slightly differently from the same base powder as far as coatings applied to that powder in the final stages of manufacturing.

Humm W-760 varies from H-414 but is the same powder. H-4350 and IMR-4350 are different powders but may be the same if they are both stamped on the same keg? This sounds just like goverment double think, double speak. What we really have is only one powder with a lot of different numbers and since each rifle is different-wait a minute I am confused for sure!

I wish I could remember where I read this....possibly it came direct from Hodgdens....

I buy Win 760 and H-414 interchangabily and have no problem and I wouldn't do this unless I was very confident they was the same.....sadly I can't tell you where the evidence was found!

Blob W-760 and H-414 are made from the same company. HODGDON NOR WINCHESTER make this powder, it is sold to them under there one brand name. IMR 4350 and H-4350 come from two different makers Dupont makes theres and i don't know about H4350. I do know H4350 is SLOWER BURN THAN

They are NOT the same powder! See the post by KLN357.

And I doubt seriously that you purchased a factory packaged 10-pounder that had both numbers on the label.

Yeah Vines I know all that, I was just carrying on a bit!

Just a thought about all this same powder thing:
I would think that a person like Steve Ricciardelli who has reloaded a few hunderd rounds would know the differance between W-760 and H-414. Just remembered this, that even with my modest reloading of about 100 rounds a week, I have seen a great differance between some people's rounds trying H-414 and W-760. A man was shooting a .308 at the range a few weeks ago and had rounds of the same case, primer, bullet and used W-760 in some and H-414 in others. The H-414 shot a lot better group than the W-760 in that perticular reloading. Same? I don't believe so, but what do I know I only watch him shoot and looked at the targets!

I just got off the phone with Mike at hodgdon powder. he told me that W-760 and H-414 were definatly not the same powders and are not to be interchanged with each other. In fact the burn rate charts read:
W 760
W 760BR
Brigs 4351
H 414
Mike did say that it was possible to get a drum labled with both because the same powder company can use the drums more than once and do not re-lable as they should. He also said that if anyone ran into this to call as soon as receiving the powder so that details of that order can be checked out. So just like a number of other powders that are almost the same in burning rate, W760 and H414 are not the same and can make a big differance in some calibers using the same bullet weight.

Read VAPOGOD post, He too has loaded thousands of rounds. with over 2700 post. I guess he and I know the truth. I too have loaded thousand of rounds. and the man with with the 308 he had different LOT number of powder. and i did not say I BOUGHT a 10 lb. keg. I don't it that much. it is very dirty.

No disrespect to anyone intended, but as reloaders we have a responsibility to make accurate observations and if we don't, it becomes the responsibility of the technically accomplished to give a "second oppinion". The number of posts a person has on a forum is an indicator of their enjoyment and participation. Very few have the ability to appreciate the invaluable technical competence of a person who has an aptitude specifically geared for technical and engineering data, unless they share a similar aptitude and drive.

Thanks to all for keeping a disagreement civil, but when we are dealing with pressures potentially in the 60-65,000 PSI range, it has to be accurate.

I have not been here a long time, but I have been involved in reloading a long time as well as engineering in a number of disciplines, but that is only as relevant as my last post. I have been to several forums since I started doing this less than 2 years ago and I have seen a number of people who expect to have consusltant status when they were not thoroughly competent on some topics and pressure being a paramount case. I am not pointing a finger at anyone so please don't take it that way.

One thing has become increasingly clear: Steve Ricciardelli's post have been very indicative of a guy that knows his stuff and I for one appreciate the level of technical competence conveyed in his post. So, I appreciate him addressing this issue, because if my lack of tenure makes my oppinion irrelevent, it is always nice to see someone like Steve step up and offer advice that hopefully clarifies things.

Thanks Steve and I have been to your website and I really enjoy your posts.

With all of that being said, I think 760 or 414 are very good choices. If you want a faster burning powder, R-15 and Varget are great, but while I have your attention I'll mention Ramshot Hunter one more time. It is like R-19 in burn rate (slower than the 4350s) and if you want to maximize velocity for hunting loads this one will help in the .260. It is a very dense ball powder (950 grams per liter) without temperature sensitivity issues common to most ball type powders and I also believe it is nearly perfect for cases like the .260, 6.5 X 55, 6.5 X .284 and 7mm-08. Yeah, it's new so data is not as complete, but more complete data is on the way from Ramshot. Trust me, this one is going to get a lot of peoples attention in the future.

I have no ideal how they will work in the .260 as I haven't worked with one.

IMO
I have to agree with Steve and KLN that H-414 and W-760 Aren't the exact same powders,similar yes,the same no.I've shot enough of both over the years in the same rifle and with different lots of both to say that.

I could care less if anyone on here has loaded 34 million rounds in the last year and I damned sure don't care if you interchange H2400 for IMR 4895 and say they are the same thing. And it doesn't matter if there are 45 labels on the drums, The people at Hodgdon told me that the wo were not the same and not to interchange them. So why not call Mike at Hodgdon and tell him he is an S.O.B. and a bald faced lier! Some of you people really think you can empress somone with all your reloading and think others don't know a damned thing. But let it be know that in the back ground there are those who speak little, do much and know the real truth.
