powder

I have an opened 1 lb container of IMR 4451. This powder has not had Tubb Dust added to it. I estimate it to be 10 oz of powder left in the jug. I can be reached at four zero five six three zero seven three five eight, calls only. $10.00 Any questions let me know. Thanks IMR Enduron 4451...

I was wondering what criteria people use when selecting a powder for handgun applications. Why did you decide on one powder over all the other options on the market? Was it a certain part of performance (accuracy, recoil, FPS, etc) price, availability, or other characteristic you were looking...
