Agreed boys; Bigger and heavier will give a better edge here for taking Moose. If one is not a BIGGER IS BETTER mentality gun hunter, then getting a big bore will not necessarily solve the problem. There is no shame in favoring the .30 and below calibers because of recoil issues...or just practical financial reasons. I know caliber versatility is a matter of opinion, but a .338win is a serious caliber in anyone's book and other then elk and moose as a steady diet it's alotta gun to tote and shoot for most hunters.
Me...I prefer .30 and bigger to take most anything and may get the .340 wthby next@just cause it's attitude!

Interesting comment about the 165 gr 30-06 being too light for deer. The three elk that I have shot with the 165 gr Sierra boat tail all ended up in the freezer.

Well, my Canadian buddies really get a kick out American hunters and big game animal rifles!
They are VERY PRACTICAL when it comes to hunting; which many use the .303 British with amazing success on wolf to Moose!
Most have the .308 in one form or another, and likewise the 30/06, but many also carry the .270 for the availability of lighter bullets/lesser recoil. With the added power of the .270WSM, I'm with WAM on this one. Using the proper bullet this should take a Moose quite nicely.

The .270 will work with the bullet in the right spot but like Shane said I personally would use a larger caliber just in case old Bullwinkle decides to not stop with one round from the .270. Not absolutely necessary but I know a .338 of any kind will drop them almost immediately with the right bullet in the boiler room.

I have taken 2 black bear, 2 mule deer, and one elk with the 270WSM. None went more than 30 yards. Great cartridge. Would use 160 grain partitions for moose or the 150 grain oryx. Place the shot where it belongs. Impressive caliber. Has become my favorite go to rifle. However, If I were hunting moose I would use my 338-06 with 225 partitions.

I have shot thirteen elk and six moose. Some of them were very big boys. My experience is that .270 is too light. I have found that my 30.06 is in fact almost too light. Moose have much thicker hides (much thicker!) and heavier bones than elk. A high speed lighter bullet will come apart too much going through the heavier hide, especially higher up on the body. Also, longer, narrow bullets (e.g. .270 and 7mm Mag) may tend to tumble when they hit something firm. I have also found that 165 gr 30.06 is too light to do a good job on even deer. Made a mess and poor at knocking em down. I'll stick with 190 or 200 gr boat tail 30.06 for moose or elk. I hunt on foot and often am in the bush hiking seventeen hours a day. Rarely do I get a shot exceeding eighty yards. I'm not inclined to be carrying around some shoulder-busting hefty bazooka if it's not necessary. My favorite gun is a 1952 760 Remington pump 30.06 with detachable 4X Weaver scope. Light weight, comfortable to shoot, versitile, and reliable.

Yes defiantly. I'm a proud owner of a 270 WSM. I reload all my shells with 150 grain bullets and i have taken down SEVERAL elk with one shot at over 400 yards. This round would be deadly for moose as long as you have good a good shot placement.

Well, my hunting buddy's son has killed 3 elk that I have personally seen with one shot from his .270 WSM A-Bolt at ranges of 150 to 300+ yards. To clarify, I saw the elk down with one entry wound and helped recover and hang. He uses a rangefinder and would never lie about the range.

Those were some big Colorado bulls, so I'd say the .270 WSM is certainly adequate for moose if it cleanly takes down big elk.
