I looked pretty hard at the 25-06 before I bought my 243 for deer (was looking for a 24/25 cal, not to hard of a kicker to dedicate to Bambi hunting).
It is probably the flattest shooting non-magnum (common) caliber out there. And yes, if you look at the ballistics feeding each respective caliber with a "typical" hunting round, the 25-06 is flatter than the 270 Win, 7mm Rem Mag and even a 300 Win Mag out to 500 yards.
If I lived out West and had to shoot longer distances for deer/other critters, the 06 would have been the better choice. At 200 yards or less it has no real advantage over a number of other calibers that have ammo available "on the shelf" in Bubba's corner store.
I see you have your location listed as Waterloo, On.
To make my point about "bubba's", 25-06 ammo has been on "standing order" for about 18 months now where I work (7mm-08 as well for that matter) - I haven't seen a box since sometime in 2013.
Can sell you all the 243/270/308/30.06/7mmRM/300RM and even 270/300 Win Short that you want.
If you reload, maybe not an issue, but if you reload then why not go with a 257 Wby which shoots the same bullets as the 06 but kicks the snot out of it any way you want to measure...
And besides deer I "might" consider using a 25-06 on Moose sub-100 yards - I would definitely use the 257 Wby for Bullwinkle.
