It seems the Hornady Interlocks are loved here on the campfire (especially that 100 grain 257 version). So I am testing factory ammo for my 270 winchester and have found the 150 grain interlocks to be very accurate.

Would anyone hesitate to use this combination on elk?

With the 270 WSM I have had great success with the 140 accubonds and elk, but the current rifle doesn't like them as well. Of the other bullets tested the 130 interbonds shoot well, but Hornady stopped loading them in factory ammo so I only have a part of one box left.

By the way - out of interest how does the 270 Weatherby perform with the 150 interlocks?

I have never killed an elk so take what I say with a grain of salt. From my experience using the .270 interlocks on deer and hearing other reviews for them I think they will be a fine elk bullet. Put the bullet in the lungs and start carving out some steaks.

If you have the skill to put the Interlocks in the animal where they belong then...no I wouldn't hesitate to use them.

I killed one big cow a few years ago with the 150 grain Hornady Interlock out of a 270. My load pushed it out of the muzzle at a screaming 2850 fps. the range was a lasered 420 something yards, ( don't remember the last digit).
At the shot, she turned 180 degrees, but didn't take any steps. I shot again, and she slumped to the ground. If I remember correctly, both bullets ended up under the hide.
I have shot a few deer with this load, and in that very limited sample, it seemed to produce quicker kills than a 150 Sirocco out of my 7 Magnum.
I posted on here a few months ago asking if anyone had ever had a failure with an Interlock, and no one related a failure. Next to a Partition, they are my most trusted bullet, and I don't think they give up much to a Partition.
In my rebarrelled model 700, they will shoot into less than 3/4" MOA.
(And, I hope Ingwe doesn't see this post and take note of the fact that my 270 load can be easily equaled by the 7X57)

hell, I've used 130g interlocks in the .270 for elk without issue.

even at short range (under 100yds) they penetrate to the far side, even if they go through the scapula first.

Ssshhhhh!

Well the 130 interlocks shoot almost as well as the 150s. The 150 just seem more like an elk bullet, if you know what I mean.

I have used the 140 gr btsp interlock on elk with great results so I would think that the 150 would do great as well.

I have two 270 Win�s.
One is a Browning and it shoots 130 gr Interlocks and 130 gr Partitions into sub-MOA groups.
The other is a FN from the 1950�s and it shoots 150 gr Interlocks into sub-MOA groups and 150 gr Partitions into MOA groups.

Haven't used the .270 on elk, but have used it on a LOT of deer and hogs (up to 400 pounds). In my experience, the one semi-failing of the .270 Win. is a lack of penetration on really close in shots when using the 130 grain bullets. Just a little too much expansion at times.

Once I stepped up to the 150 grain bullets, that problem disappeared (except for flukes which can occur with ANY round.) To me, the .270 (with 150 grain bullets) performs almost exactly as does the .30-06 with 165-180 grain bullets. THAT round has been an elk killing standard for years......so the .270 with 150 grain Hornady's should be great on any but an extreem angled shot ffrom the rear.

I wouldn't hesitate to use a 150 Interlock on elk at 270 Winchester velocities.

I've shot quite a few deer with the 270 and 130's and a few at 25-50 yards with plain old SPs. All blew right through. If you're not getting penetration with a 130, I'd say it's more of a bullet/placement/shot choice issue rather than a cartridge one.

I counldn't agree more.

130 grainer through the heart/lung area = heart/lung soup.
