Have any of you guys ever seen the meateater episode where Steven Rinella and Ryan Callaghan get false charged by a grizz with 3 clubs in british columbia? The false charge is on youtube if you haven't. They see that bear from a long ways away and know she is there as she works her way closer and have a lot of warning when she charges, but if it had been a real charge I still don't think Steven Rinella would have got a shot off because he had his gun on an empty chamber. Ryan Callaghan was a little quicker on the draw and does get a shot off in front of the grizz that helps turn her, but I can't help but think that if they didn't know that bear was there and got charged for real they'd both have been mauled right then and there. If I'm in grizz country, whatever firearm I am packing has one in the chamber without a doubt.
I have carried one in the chamber rifle hunting most of my hunting life and never once have I found my safety not in the on position unless I was taking it off. I hunt thick crap too, but I guess maybe I just watch my rifle more than some. Sometimes if I'm climbing something especially steep and slippery where I'm likely to fall I will put it on an empty chamber, but that's about it. I have shot two bucks that I jumped where I didn't expect to find them that I'm not sure I get if I have to take a second or two more to rack the bolt. If it makes you feel better to carry empty, go for it, but if you observe basic gun handling principles I don't think there is anything wrong with carrying one in the chamber. It also means one more bullet before you have to completely reload. Not that its always important, but anything that can avoid having to dig for shells is a plus.
