You can still get it in 500gm tubs. Its a large green flake powder and about 6gns half fills a case. double load spills out the top.
Use it with a 200gn rnfp bullet and you have a soft shooting clean burning load.
I moved to CSB5 after the lack of bulk AS and that works well but is a dark colour so not so visible in the case when loading.
Both of these are fast shotgun powders.
Another excellent powder is Vectan BA10 - which was very popular in pistol days and is also brightly coloured and clean burning.
The Vectan AS i used to use was green and PINK flakes. The malachite green stuff was Vectan A1
