for a caribou you dont need a cannon for sure.

i used for years while guiding a 300 savage with 180 grains due to black bear problems...

but i ve seen enough caribous killed with .270 win that i can recommend to use the bullet your rifle shoot well ...
at home we re using a 270 too that is loaded with 150 grains nosler partition just because we can meet moose and grizzly too ... but i have a 375 ruger for backing up ...

Today I use mostly Nosler partitions and Woodleighs in all my big game calibers 270 and up...

I used a lot of Rem. corelokts and Win. PPs over the years and have no complaints with them.

I still use these two bullets in my Sav. 99,in 150 gr. Win. PP the 180 gr. Rem RN corelokt 308 In my 250-3000 I use the 100 gr. Rem corelokt almost exclusively and on ocassions I use the WW Silvertip.

I like the WW Silvertips in lighter calibers only, as I have had bad luck in the bigger calibers, 30 and up, WW keeps changing them and sometimes they work then they change them again and they don't work so well..WW needs to adopt a policy of "if it ain't broke, don't fix it"

Not the best picture but here is Nosler Ab recovered from Caribou's far-side hide

I have been shooting the 270 for better than a lifetime and am not a fan of the 130 grainers. Not because they didn't kill any quicker but because they had questionable performance. Assume you miss that vital area? Assume you catch bone rather than slip that skinny jacket past the rib cage. I vote for the at least the 140 grainer and would prefer any 150 for the 270. I have never recovered a 150 grain BT because they have all passed through.

Not a fan of he 270, but I witnessed a shot made on a 5x5 bull elk a few years back in western Colorado.

The shooter was using a 270 with 150 grain bullets, don't know what flavor, but the bullet broke both shoulders and clipped the lungs.

Bull made it about 10 yards or so before going down. bullet exoted leaving a fist sized hole, onme of the hunters had a range finder with him and ranged the bull at the shot at a little over 500 yards.

The hunter put the bullet where it needed to be and the bullet did the job it was sent to do.

Caribou are not bigger or tougher than elk, so you should be in good shape if you can shoot accurately.

I have never been able to tell the difference on killing effect on deer,elk,bear or antelope with any bullet from a 130-140-or a 150 grain bullet. And they ALL SHOOT FLAT...

And that includes premium bullets as well as standard cup and core bullets.

But I see some very sound advice on this topic about running into Moose and Bears that might pop up at a very inconvenient time.

SO a premium bullet in the weight of 150 grains would give an extra margin of confidence in my book.
