favorites are hard to call, just like which child is your favorite - they all have their moments.
However, the Win70 in 270wsm is my most accurate and favorite for long range shooting. (I have hopes the new criterion barrel 6.5x284 betters this however)
45-90 with a puff of smoke is a hoot, and I like the long barrel with peep sight too
shooting 38sp, 357mag, and 357max all at the same sitting is a treat also (I think this will be a great growing gun for my kids in a few years - easy to shoot/practice and can take a deer)
30-06 is usually my deer season barrel (truth be told, all I need)
Both the 25-06 and 35whelen are savage barrels that replaced HR barrels I sold, 243 may soon follow cause I like my 26"flutted barrel by savage more.
Re: 17cal or 204 for that matter, heck a 223 is too small for my taste
I was thinking mostly of my reloading and barrel swapping at first, and left more than a few others off the list, which I better keep incomplete for fear this may make its way to my wife somehow
but I do have the 50cal in muzzleloader.
375 seems to be missing - I dont know why I never got the itch for a 38-55 from HR, and I sure would like a 405win, but would rather it be in a 1895winchester than HR.
