Consistent max velocity in extremes means it works in hot or very cold temps to me not stability over a range
None of them say those exact words, but OK thats fine. Now what do all these statements mean to everyone else? Almost every bottle has a different statement.
- RL15 says "consistent at all temperatures". That's a pretty plain statement that means to me it is resistant to any changes in the load regardless of the temperature. But according to the rep it's not one of those powders...umm ok
- RL17 says "consistent max velocity in extreme weather conditions". What the heck does 'weather' and 'max velocity' mean???

I can't change the speed of bullets coming out of my barrel unless I change my load. Does it keep the same speed regardless of humidity and barometric pressure??? Does it mean it wont slow down in cold temps but will speed up in warmer temps? Every rifle can have a different max velocity too. The statement makes no sense whatsoever.
- RL 16 and 23 state "consistent across temperature extremes". Sounds like the same statement as RL15 with different wording to me.
- RL26 states "excellent temperature stability". Ok, what's stability? Ignition? Speed? Accuracy? I would assume they mean speed. But again, the rep says this isn't a temp resistant powder.
I know how they all act because I have used them all extensively in testing and all temperatures. I just don't understand why they have all these different statements on the bottles. It's ridiculous. When you see a can of Hodgdon, if it has the "Extreme" logo on the label you know it is a temp resistant powder. Plain and simple. The new IMR powders, you just look for the "Enduron Technology" logo on the label (and the screwy numbers that nobody knows by heart yet). With Allant, the only "logo" they have is the "TZ technology" on RL16. That I KNOW is a very temp stable powder. I've tested it a lot and use it in one of my hunting rifles. Why doesn't 23 have that logo?
I know they have multiple factories making their powders and that may be the issue. Can't lock down onto one good temp stability technology when the other factory can't or won't make it the same way for them.
Again, I really like Alliant powders and I know exactly how each one will act in many different calibers. I know I can only test loads with certain Alliant powders in the temps the rifles will be shooting or I risk a change in accuracy. But for people new to using them, the labeling can be very misleading. They may think they're buying a temperature stable or resistant powder when in fact they are not.
