Danny,
Welcome to GTA. You won't find a group of friendlier and more knoweledgable men and women (there's a few lurkers here) on any board. Got a question? You'll find at least a few answers here. Every now and then they may agree! LOL
Plus you'll also find some insomniacs from the US that will be on all day and night so you never know who's going to give you an immediate answer (are you about 12 hours ahead?).
Anyway welcome and if you like to tinker give us your questions and show us your work and ideas.
Andy Wong aka larspawn
P.S. are barrels rifled counter clockwise down under?
