My luckiest gun is a flintlock Tennessee Long Rifle in .50. Every deer I've ever seen while deer hunting has been while carrying that. I've got a Ruger No. 1 in .308 that I've carried for 3 seasons and never seen anything other than tracks, rubs, scat, or scraps. I'm not going to call it unlucky until I get a couple of uninterupted seasons (I'm in grad school so I don't get a lot of hunting time), but sometimes it has me thinking...... :?
On a side note, a few years ago, I came out of the woods from a morning deer hunt (didn't see a thing), put away the 30/30 I'd borrowed, and got out my .22 to meet my dad for a squirrel hunt. Within 20 minutes of the squirrel hunt, 4 does walke passed and stopped in a clear spot 20 yards away and stared at us for 5 minutes. EEEEK! Made me wonder if you could kill a deer with a head shot with a .22. This was not the first time this senario happened with this gun, so I wonder, can you have a "lucky/unlucky" gun that brings out game you can't shoot? :-D
