RE: 25-06 or 270 question
 

I would be perfectly happy hunting any one of the deer species we have with a .270 up to and including Alaskan moose. .270, .280, 30-06 etc... flip a coin IMHO.

But since you added things like polar bears to the list I would not hunt them with anything less than a 338 Win mag.

If I were doing what you are doing I would have a .22 center fire, either a .270 or 30-06, a 338 mag of some kind, and a big bore like a 416 or 458. Four cartridges and you could hunt anything in the world.

back in the day the world record polar bear was taken with a 270 win. that particular bear has been surpassed, but it wasthe record at that time.i have taken several moose with a 270 win and it works fine if the shooter does his/her part. that said, i'd suggest the 30-06. it's killed every animal you listed and all the rest you didn't mention, and is quite sufficient for anything in north america (again, if the shooter does his/her part).

I would cry if I sold all my rifles and reloading equipment. I agree with the other fellers i would stick with and 06 min.

RE: 25-06 or 270 question
 

If you are keeping a .30-06, I would get rid of the .270 and keep the .25-06. On the other hand, why reduce your battery at all? You won't get full value for them when you sell them.

RE: 25-06 or 270 question
 

i would suggest a 257 weatherby mag up to elk sized game...maybea 280 rem....but for the biters i dont think i would chance it with anything under a mid-big 30 cal..its kinda funny that in all the years of gun making no has ever hit upon that magic rifle caliber..one gun to rule them all....

RE: 25-06 or 270 question
 

Close to half of the hunters in the group I moose hunt with use either a 270Win or 270WSM.The rest are a mix of 30-06,300 win mag or 338.Much the same as many other big game hunts people should worry less about choice of caliber and more about shot placement,type of bullet and being consistently accurate with whatever rifle they are carrying.Make your first shot count!
Good hunting guys

RE: 25-06 or 270 question
 

Ive been on a few hunts in Canada and most of the require a 30 cal minimum and a few have required a 300 Mag or larger. Just to keep that in mind when deciding on one rifle.

RE: 25-06 or 270 question
 

I have the Marlin .450 and you are right you can hunt anything that walks with it. Though I have to shoot it left handed now because I shattered my right wrist right after I got it in an accident. Though a .45/70 is hard to beat for a single gun to do everything so is a .30/06.

RE: 25-06 or 270 question
 

For North America the 270win is great it kills deer elk and moose just fine. For the big bears the 30-06 has killed more bears than any other cartridge and it most likely will continue to do so for a long time. I would prefer the 35whelen loaded with 250gr partitions over the 30-06. Remember the 222rem has killed a slew of polar bears! In a sako it was the prefered native polar bear cartridge.

I this world of new and newer guns Anyone with a 222rem, 270win, and a 35whelen can be very well fitted for any North American game. Through in a 22lr and a 12ga and you pretty much complete.

RE: 25-06 or 270 question
 

Neither of those calibers is ideal for SOME of the game you mention. BUT, of the two, the 270 is by far the best because you can shoot the Nosler Partition 150 or 160-grain bullet from it. The 270 is adequate for all North American game, if you use either of the two bullets I listed and are a good shot. It also helps to know bear anatomy!!

When I lived in Alaska, I used a 270 carbine with the 150-grain Nosler Partition bullets for everything in the state. BUT, I never tried it on big bears!! However, there was a doctor's wife in Fairbanks who used her 270 on Polar bears with good results. Her load was the 150 Nosler at 2900 FPS MV....

For lion & tiger (if there is anyplace left on earth where you can shoot tigers!!), I would use nothing smaller than a .375 or a .416 Rigby!!
