Thanks mike, but I would not be looking to do anything for 16 or 10.

It looks like this AL7 may be going down the road at the next shoot.

I’d be intrested to know your 10 gauge load . I have loads for 12-28 using Unique but not for the 10 .

I stand corrected Brian. It was AL-8 that was for 12ga magnum loadings. I think I confused it with HS-7. Each of these cans are about 1/3 full. I have had them since the mid 70's. I believe recipes that came with the old Lee Loader called for them and that is what I started reloading with way back in time as teenager. $2.64 for a half pound of powder, imagine that.

Unique one of my favorite powders for 20 G 3/4 oz in roomy hulls like Gun Clubs. Jug of Unique you can load almost anything shotgun rifle pistol. Not optimal for all but still useful cartridges.

Al-7 was a fairly slow burning powder used for 1-1/4 oz and up loads in the 12 and 7/8 and 1 oz in the 20. If you can find an old Lyman 'First Complete Edition' hand book you will find quite a few loads for the old Alcan powders. I am still working on a large can of Al-5 that I picked up at a garage sale a while back. Hs-6 and Unique are still common so there should be lots of data out there for them. Most of the data I have for these seem to run higher pressures, though. I still have some old Alcan Flite-Max wads in the basement.

Now I know why I had the partial cans of AL-5 and AL-7 from my youth, and why I thought AL-7 was a 12ga magnum powder. Here is the charge table from my vintage Lee Loader.
