I hope 22lr counts, because it easily tops the list.
#1 Win 94-22, my birthday present when I was 10 years old. I don't know how many 10's of thousands of rounds I've shot out of that old rifle. It was my dependable companion during my formative years.
#2 Original Rem 700 BDL 7mm Rem mag (I grew up with this rifle), from 14 yrs old until now, it's been on nearly every big game hunt I've taken. It has somewhere around 40 biggame animals to its credit. It's on it's second barrel, 4th scope and second stock. It's not much to look at, but it is an honest .5moa rifle. With bipod, scope and shells, it weighs almost exactly 8lbs. It shoots WAY too good to be sooo light. (largest mule deer taken with this rifle is 34.5" spread, shot one time in the heart at 780 yds).
#3 338AM from Kirby's shop. It's just too perfect to be any further down the list. Only has 2 elk to it's credit so far, but only 2 shots at biggame, so the average is right there. (average distance 514yds)
#4 Remington 700 ADL 243Winchester. It's an old (5 digit serial number) beat up ADL that an older lady hunted with out west. It shoots too good to mess with. I intended to shoot out the barrel and use the action as a build platform, but everything I shot in it is sub 1" and I suspect it had less than 200 rounds down the tube when I bought it, so it is staying a .243 for the time being. The stock was cut down for the original owner and I use this rifle when the weather is really cold, because with the added layers of clothing, this rifle fits me perfectly. It's also a great rifle for the kids.
#5 My dads Remington 700 BDL 7 Rem Mag. I shot my first Muley with this rifle and have watched my dad shoot a ton of animals with it.
