Use this thread to post your Alliant powder data.
Regardless of an accurate scientifically correct answer you can expect from anyone with liability (mfg) to advise the safe route of throwing it all away... and advising that you buy more. I was wondering if you have a chronograph and hadEsteemed colleagues,
If this post is misplaced, my apologies. I have no load data to share. Just a question about my Alliant Power Pistol propellant.
In a situation, say, where you are given ~2/3# of Alliant PP that has sat in a covered Dillon 550 powder hopper for about a year, would you feel safe loading it, toss it, or other? Planned use is for either 10mm/.40 from G23,29,20 for practice (the only pistol carts.I hand-load) I used to be fanatical about cleaning hoppers to nary a remaining kernel/flake,etc. then restoring powder to original factory container when I'd change propellants.
A serious car accident disrupted loading season where said system was abandoned in place in a Fla Garage. No time and bigger issues prevailed over emptying/storing unused powder. When added originally, the powder was fresh.
There it still sits...about 200 rnds worth of target/practice loads...but not quite as fresh after going thru the temp, humidity ranges typical in C. FL. 30-35* lows with 50-60 humidity; 100-110* w/ 90-100% humidity from June-Nov. (you get the idea. )
Perhaps someone has experimented in such a situation as well? Or can share wisdom that can provide a 'litmus test' of sorts to qualify the chemical changes and burn characteristics deltas of propellants exposed similarly?
So your thoughts are valued and appreciated.
In short, Power Pistol in garage 550 Hopper 12-18 months - toss or load?
Go? Or No-Go? :dunno:
The last paragraph sums up my hoped-for answer, Shadow. I have some Ranier 135 FP plateds I can load in .40 for my G23 and work up from low to mid charges. Hopefully I'll get a combo that shoots well. I just want to make sure that there isn't any unforeseen reaction probability that is dangerous. I'm not experienced enough to make a decision about this matter or even old powders' on-shelf micro-reactions since I've only been handloading for a couple years.So you left powder in your powder hopper, possibly capped closed. Although these conditions are not perfect, the powder performance may in fact surprise you. Well these powders are made to handle some extreme and harsh changes in temps/humidity, having coatings on them. I would say test with it and have some fun doing so. Make up some cast or plated rounds to play with. I have ammo that is over 30 years old I loaded and it test within 10 fps of newly loaded ammo, even being different lots I'd say that is great.
I just help a fellow that had some unknown powder, where he sent me a sample of it to identify it and developed some loads for it so he could make use of the 8lb he has...everyone told him to throw it away. It made some nice test loads in 40S&W and 9mm.
With powder being harder to find these days, I would test its use, it might just surprise you just how well the powder will perform.
Good luck!
Very nice. I too favor BD over LS. Good stuff!Here is a load I tested in my Glock 20 with 6” Lonewolf Barrel and 24# recoil spring today. The brass says the load is very mild as the primers are nice and rounded and the there are no ejecter marks at all. I will test it in a 5” RIA 1911 tmrw and update.

I’ve been trying to find a load these bullets liked and it ended up being BD that was the game changer. Nice tight groups and low sd numbers now. Before my go to was either 180 or 200 XTP’s and longshot. Now to play with this powder and Mcnetts 200 cast lead as I think they can really move using this powder.
