afternoon all... it seems like in the area I live the mid - west unigue powder in harder to get. I was at a gun show today everything but that one ! now what is the next best powder I can use ??? I reload for 38 357 32 auto 38sw 30-06 45 -70 in the carbine it will not eject the round but other than that unique works for me !!! but I keep imr 4227 for the carbine a powder that is still easy to get !!! ....thanks bill
Why not just look through a reloading book and work by process of elimination? Start by finding out what's available and then figure out which one does what you want?
L O L I did the big lyman book, sees like nothing compares to unique that's why they call it unique I guess evening looking at burn rates up or down not much to that seems like 1 or two of could work BUT all of mine was hoping I could find a fast answer for this question WHIT OUT going through that trouble was hoping with all the people here some one would have a good answer !!! ??? thanks bill
I use three. Unique, Bullseye and Win 231. I've bought them at gunshows for years and have scads around...each seems to do what the others will, except for the M1 carbine. For that I used IMR 4227.
Yeah, pretty much. The hell of it is they're all scarcer than match grade buckshot around here.Quote:

I knew the stuff I was buying would come in handy...
I too like Unique powder. I use it from handguns to cast loads in all my milsurps. Red dot is another that works for me in the cast loads. I had the chance and picked up a bunch of SR 7625 that will work for both handguns and cast loads in rifles.
hey all me again !!! bill if I try and find a new powder to replace unique with and also easy to get yet !! what would be possibly the first item to look for or : the relative burn rate ? feet per sec ? or cup pressure ? or just go one above or one below the burn rate of unique ? it that is possible ??? thanks bill
It's not only the burn rate that affects performance. Powder composition and granule form also have a potential influence. In general, double-base powders' nitroglycerin content helps promote easy ignition and burning at low load density and pressure, while increasing flame temperature and consequent erosion at higher pressure. Also, flake-type granules are easier to ignite and burn than denser tubular and spherical shapes.
If you like Unique, consider similar Alliant powders (double-base and "flake" geometry) in the medium-fast range. In order from a little faster to somewhat slower these include:
Green Dot
(Unique)
Power Pistol
Herco
Blue Dot
(Alliant BE-96 and 20/28 are newer powders in the same range and could be worth trying if available.)
All these are slower than normally needed in light to moderate handgun loads where Bullseye, 231, Red Dot, 700X, and similar quick-burners are usually more efficient and cost-effective.
thanks for the info .... I got out my new an old lyman books and looked through then of the 4 powders I thought best for me were no 1 sr 7625 then imr4227 kind of weird sr7625 my work according to lyman in my guns but no listing to be used in 45-70 and may not be able to use im4227 in my 32 auto according to lyman ... but I guess I have to start some where and if sr 7625 is in supply not like unique I may try it ! thanks bill until I blow up a gun
You might take a look at Trail Boss, it pretty flexible and will work in a lot of different applications. - Bob
See burn rate chart.
Hodgdon's Universal is right next to Unique on one side and Alliant 20/28 on the other.

Wish I could find 231 I haven't seen any for almost 5 years now. HP38 can be found and it's identical to 231
Saw some 231 at Cabela's in April. And didn't buy any, figuring there would be more coming (and had ~9 lbs at the time). Thinking that may have been a mistake....
