I need your opinion on powder. what powder seems least affected by weather like pressure, temp, and altitude.

The Hogden line of powders that are made in Australia by ADI are specially formulated to resist temp / pressure changes. No powder is totally resistant to temp changes but ADI powders are close. The following powders are all made with the same ADI technology .H4227H4895H4198VARGETH4350H50BMGH4831H4831 SCH1000RETUMBOH332 , Benchmark . I have a chart of the effects of temp on certain powders but I can't get it into this post for some reason. I don't like the way this forum operates .

Re: Powder help

1st -Don't believe the hype or herd murmuring..
Everybody says that whatever they use is great, because they aren't going to tell you that what they use sucks(unless girlfriend talkin).

2nd -Nobody can predict it for you..
There is no actual basis provided for any claims out there, variances from lot to lot, and there is more than powder affected by field conditions.

3rd -You can test for yourself to see what does what to YOUR load, in YOUR barrel(local basis)..
Keep logs, tweak QuickLoad and ballistic software.

You don't know what you are talking about . ADI powders are proven to be less temp sensitive than all others. It's just that America does not know how to do it we do. The US has been trying to buy ADI for years and has offered many millions.To get it's hands on the secret. Hogden knows this and uses ADI powders . Don't put down what you don't understand .Varget has 5 .6 times less velocity change to temp as W 748 does.Varget has 4.8 times less velocity change to temp as Accurate 2520 . However if you want a powder that lasts the longest in storage then buy Win ball powders as it has long chemical stability. Every powder has it's good and bad points.

Re: Powder help

In Barnes tests they found Ramshot Magnum to be more stable than H1000

Re: Powder help

Show me the proof Bullet Bumper..
Show the testing, conditions of testing(qualifiers), results, and independent validation of any claims that correlate to OUR field use.

I'm not making any claims about Hodgdon/ADI. You are..
And I'm excited already about the basis you must have for this.
So bring it, please

What is it that America does not know how to do?
Is it shooting Hodgdon/ADI powders?
Cuz I'm just guessing here that we use more of these powders than the rest of the world combined. Who other shoots so much and with so many cartridges, conditions, and sports, than Americans?

Now I hold no basis other than my experience.
I suggest to thread starter that he seek the same basis, because it's possibly the only truth for him.

I probably hold 300lb+ of Hodgdon at the moment, along with many other powders. In the past 30yrs I've shot up twice as much I'm sure. I like Hodgdon powders, and IMR, and I can manage my loads with their performance, specifically w/regard to cold bore accuracy.
IMO, mentioned testing with an implication that Ramshot beat Hodgdon in temp stability, may or may not apply with varying cartridge/load/barrel combos and shooting. But it's interesting info.
I've read a test in this regard where IMR4350 beat H4350 in temp stability. I happened to hold the perfect gun to test it myself, and I did find the same thing -with MY lots.
So I've got a bunch of H4350 I don't use yet, but it might do better down the road,, with another configuration.

So regardless of claims, I haven't seen predictable improvements with powders any more so than primers or bullets. I am the end user, and it falls on me to find the best combinations.
I suspect that no amount of merchandising fluffery will change this, but maybe you can change my perspective.

Re: Powder help

Here's a link to the Barnes tests.
Like Mike said they are interesting, and the H1000 and Ramshot Magnum are very close, but Magnum edges it out. Not bad for a ball powder.
I like Ramshot Magnum alot.
