I was told by a fella in the Vic licensing branch that SA had banned the 338 Lapua. Sad that you confirm this.
I always had the impression that when it comes to loony laws Victoria led the way.
I did hear that some ranges don't have the correct "safety template" and I know there are only two ranges in Victoria where a 50Cal can be used (for that reason).

Did the folks at the meetings tell you what the justification for the proposal was ?

I only ordered my 338 Lapua when I heard about SA - I figured this would be my last chance. The Vic licensing branch told me that club members would have no problems. I know its the Thin end of the wedge etc but I see nothing to do but carry on and hope for common sense.
