Except for the .270 Win,
None of the other 5 calibers I have used to hunt with (not always successfully) or will use this year are on your list:
2. .243 Win
3. .25-'06 Rem
4. .45-70 gov't, and
5. 6.5x55mm swede
(and .50 cal inline muzzleloader)
so I don't know whether to vote none of the above or .270. Can you modify your poll to include more choices?? The two most commonly used (to be used this year) will be .243 and .45-70, but I plan to add a really good 6.5x55 as my primary deer rifle when I get the fundage (probably a CZ 550). I consider my .308 win, my 7mm rem mag, and perhaps the 7.5x55mm swiss to be my elk rifles, along with the .45-70 as well (though never actually been elk hunting yet). I also have a 10mm carbine, .454 casull revolver, a .223 rem, and a 7.62x39mm which I *in theory* may try and use at some point on whitetails. Also want to add a .35 rem marlin 336 for a brush gun at some point. Oh, I did hunt 2 days last year with a .44 mag revolver...no deer seen.
