Just looked in Speer 5&7, Lyman 45 and Hornady manuals, they only show AL-5 and AL-8 in all loads, sorry.

Alcan 7 load data--This is right from the book Alcan Reloaders Manual XI dated 1966 (The recomendations in this charge table are maximum loads and should be approached with caution. Suggest a one grain reduction for initial loading.) The question marks in the 357 Magnum velocity column are because those last two digits are obscured and not really sure what they are.

Handloaders Digest 6th Edition also shows AL-7 data in the 357 Magnum on pages #18 & 21 under ballistics table I and II.
It can be found and downloaded from http://www.castpics.net/ It is under references tab and then under the reprints of cataolgs tab. Its the 1972 Handloaders Digest.

I have not had a chance to check online for 44 or 45 data with Alcan-7 yet. These were just information that I already had. I hope it helps.

Thanks for the info.
Alcan 7 was my hands down favorite powder in 12ga field loads. What made it so special in my book was that it was slow but an alcan rep told me that it was progressive burning. He explained that it started slow and accelerated as the burn continued. I don't know about all that but I do know it made some of the best 1 1/4 lead heavy field pheasant loads I have ever used. They would flat roll a pheasant out to 60 yards with a modified choke. ... the down side to it all was it was DIRTY with a capital D. Its one of the things I am still pissed off at Smith and Wesson for. I do so miss that powder. I never tried it in handguns though.
Using my never-fail "mystery powder" method, but skipping the first two trials, load a few test shots using BlueDot Start loads. Compare the velocity you get with what BlueDot would have given and adjust your workup loads accordingly.
I fund AL-7 to be close to BD in handguns. I don't load to maximums and stopped at about 90% of the velocity equivalent BD loads would give.
For those who have never seen the several posts I've made on this, you begin with loads at Bullseye charge levels. (I use .38 Special loads fired in a .357 Magnum revolver for added safety.) Compare velocity. If the mystery powder shoots as fast as Bullseye loads at that charge weight, use Bullseye data for that powder. If it is slower, repeat the test with Unique data. Then Blue Dot data and finally 2400 data. You will be able to quickly and safely determine the mystery powder's burn rate compared to a well-known powder.
Thanks rocky.
Clever. Another thanks to Rocky.

Just to be pedantically complete, be sure to use START-level loads at each step. And, to be absolutely sure about the delivered velocity, it's best to have chronographed the same loads with Bullseye, Unique, etc IN THAT GUN.
