They start you on a bolt action .22 rimfire and show the basic operation,safety considerations,gun handling,muzzle awareness etc. and talk about safe shots,backstops etc. It's excellent stuff for novices.
On the range you'll get to fire the .22 from different positions,sitting,kneeling etc. and once you are comfortable with that you'll move onto a fullbore probably deer legal calibre like .243 or 6.5 and do the dsc1 shooting test...with the advantage of tuition
.
I think they try to avoid anything bigger than 6.5 at this stage as there's no need to introduce a beginner to being "recoil shy".
