The Shamal was AA's first pcp rifle first seen around 1987 in prototype then production from early 1998.
They were indeed used for FT and could be considered the rifle that really kick started the shift to pcp in the sport.
They were offered in two stock styles - a sporter available in beech or walnut:

and a target style stock with adjustable cheekpiece and butt pad:

Nick Jenkinson's involvement with the rifle came through his winning one then going on to win just about everything he turned up to.
They were indeed designed to be full power, I have not heard of a 10m target version, but that isn't to say one wasn't converted for that use.
Example of a custom Shamal with shortened action, regulated and custom FT stock, believed to be from Dave Welham Airmasters88:
