Only ones of merit. I am not a believer in luck but I've carried some guns day after day deer hunting and never saw a deer. I named those the same, gone.
I have my Dad's old 1952 Win model 70 in 270 Win, it was named by his hunting buddies, "Old Nutts". It always brought home a nice buck.
I have one old pre 64 M 70 in 270, I call her Miss lucky, take her to the woods and stuff comes running at you to die. My wife used Miss Lucky for years and caller her big thunder.
Some years ago my wife complained about the weight of Miss Lucky with whom she had bagged many deer. I bought her a Kimber M84 in 7mm-08. The first year with it she killed a big wall hanger. She now calls it Little Thunder.
Most are tagged with names like, Dad's Ruger SS, Uncle John's high standard, Gramps 45-70 trapdoor. So I guess these are family names.
My first Python was a NIB 4" Nickle. It was my carry LE gun, I shot it lots and lots, mostly m8 38 Special wadcutters. I squirrel hunted with it, killed 2 large cotton mouth snakes that were too close to my kids with head shots and a few more vipers around the house. I knew the gun was a she, She did not want to disappoint me, she never missed, I called her little Miss serious. Of all my foolish trades that is the one I most regret. She's laying out there with some ham handed dolt getting more ticked at me by the minute for dumping her. The 5 or 6 Pythons that followed were nothing but a gun. No attachment at all. Just pretty bimbos that were sent on their way.
I had an early Weatherby 270 WBY on a FN action, very low SN. She had a built in wire guidance system. She did not miss. I once shot a buck from one farm, across a wide creek, across a gravel road, no traffic if you;re thinking about it, and 400 yards into the next farm.
Folded that boy like a wet napkin. The folks hunting the next farm on the farther left end came down to see it, they were watching the buck cross the farm, heard the shot and saw it fall. They came down to see where I had shot it from. The guy who owned the farm we were hunting on had the OK to hunt that farm. He kept saying he shot it from here all the way to over there. His jaw spent time laying on his chest. Mrs Model70 was hunting with me. The guy said was that luck or what? She said no luck involved. He's done this before, never saw him miss. What a good wife, but this is not about me and that one shot, it is about me trading off that gun to make myself use Old Nutts that Dad gave me.
Old Nutts has it's history with Dad and now lots with me. I use 270 Win loads that mimic the 270 WBY load. It is old stock 270 Win ammo by Weatherby. I found some and bought a case. It shoots 200 FPS faster than the 270 Win. I call that ammo wicked.
