KWC: thanks for that link. I shoot competitively and have restricted my trips out of state due to the NJ and NY 'rules' being somewhat vague.
I believe the federal rule for transport is something like: being legal to possess at both ends of your journey, making no unnecessary or prolonged stops, and transporting firearms and ammunition in separate locked compartments not accessible from the drivers seat. I think this is how out of state folks transport their firearms to compete in NJ and NY.
I have letters to the NYSP Commandant and the NJSP Commissioner to clarify the competition issue, but have not received replies [ x3 to NYS since the SAFE Act; and x1 to NJ ] to date.
