I have been trying out some of the Alliant MZ powder out at the range...At first sight I thought it was very coarse n ext to 777 and pyrodex select and I had a problem feeding it through my dispenser....but I soon found the answer was to shake the dispenser a few times with my finger over the spout and the button depressed and that worked good..It fired up every time and after shooting it all morning in my inline and sidelock with reasonable results I decided I liked it and for $9.99 a pound I thought it was a great deal....I decided to buy another 10 lbs but found that Sportsmans Wherehouse online store has sold out...but....some of their stores still have some....of course here in N.FL there are no stores but I did find a store in Phoenix and they put 10 lbs on will pick up for me..and yes I just happen to be going there in two weeks so I will ship it back to myself..I think I will buy a cpl of extra pounds for LAG's to try...so if you like reasonable cheap powder and can find some in a store close to you...better get some quick
