I got a couple 'comments' during my test. I aced the test, and the guy had a couple 'huh, good idea' things. The guy goes to hand you the rifle, you tell him to open it first - every time. Once he checks it, remove the bolt and check the barrel for obstructions (every time) using a ceiling light - there is a tool in the room to check a rifle without a removable bolt (better yet, bring it yourself. When the tester says... 'I'm a CO and I've asked to inspect your firearm' - ask permission to open the action first, then offer to show him your PAL. As I'm sure you know -they like consistency. simple stuff.
Sometimes they don't get consistency! I was coming out of the bush from a few days of spring grizzly hunting when stopped by a C O. He looked a my licence and tag, then said he wanted to see my limited entry authorization. I said, "Oh dear," then explained it was in the box on the rear of my quad, my quad was backed into the canopy on my truck and impossible to get out, unless I unloaded the quad, but first I would have to unhitch the trailer. He made no indication of relenting, so I told him, "You have a list of all fourteen permits in your area, just look at it and see my name." He went to his vehicle, got it out and checked my name.
I was alone in my truck, with my 30-06 rifle beside me with the bolt closed. He said, "Is that rifle loaded?" I took it out, being very careful where it was pointing. I pointed it up, and with a bit of fanfare, very sharply flung the bolt open! I looked in it, as he was doing, I stuck my little finger up the chamber, then said, "Huh, not a darn thing came out!"
An old logger then came along and the three of us sat around for about a half hour, having an excellent BS session.
This was the first time I had ever seen this C O, but in years past I have been on many hunts with game wardens.
