I posted this somewhere else on the forum--I just got a new 270--and even though I hand-load I bought a bunch of off-the-shelf factory stuff just for harvesting brass and seeing what they could do. I almost never buy Winchester factory ammo--except their shotshells--but just for the heck of it I bought a box of their powermax bonded in 270. I was blown away by how well they shot--they pasted every other cartridge I bought including several mentioned here already. It looks like a very well designed bullet the "protected hollow-point" looks like a berger from outward appearances. I haven't hunted with them--at least not yet.

Try looking at these recommended bullet weights: Ideal Bullet Weight (http://shootersnotes.com/ideal-bullet-weight/).

There is a reason the 130 grain bullet has been vastly successful for deer with the .270 Win. If you choose a good premium bullet instead of of the classics, then you are good to go for Elk too! Partitions or all-copper hunting would be a better choice, however, if you are serious about Elk and a 130 grain bullet.
I hunt with a .30-06 with 130gr spire points...if the .270 is anything like it in that weight, I personally would not use it for anything bigger than white tail and/or mule deer Its a devastating load on deer, bullet disintegrates but won't pass through the ribs on the far side at ranges of no more than 150 yards (what i use it for).

Ammoguide.com lists velocities of more than 3300 fps for that bullet. If you load the bullet for a faster muzzle velocity than the 3000 fps seen in classic 270 rounds, then the bullet is going too fast! It will definitely come apart too soon.

Dial your velocity back to 2850 - 2950 fps and you will find the round a lot more pleasant to shoot and you'll get better performance on target. The difference in drop at your stated max range of 150 yards is small enough that a simple zero of an inch or so high at 100 yards will make the load good to go.

This round was worked up by my father and myself...its brought home more than 75 white tails, with at least 50 of those from the 110e it was originally loaded for alone. The max I use it for is 150 yrds, because that's how far you can see not because of the round...it punches a solid quarter-sized 5-shot group at 100 yrds.

I'm not changing a thing...

I only posted because I feel a similar load in a 270 would be too light for anything heavier/denser than deer and that I would give real world results for a similar load.

I haven't hunted the 270 yet--but I wouldn't worry for a second about it's stopping power on Elk--in fact one reason I bought 270 was it's outstanding balance of ballistics, long-range performance and relative heft of projectile. A quick glance at my Hornady manual reveals the vast majority of their offerings in 270 130 gr on up are rated to large game.

A simple 130g sierra prohunter will kill anything most of us will ever encounter,deer,elk goats ect.

(.270 Win 150 NBT vs .270 AI 175 Matrix VLD)

My current accuracy load for .270 Win (fireforming to AI) is 2919 FPS.
My current accuracy load for .270 AI is 2993 FPS with 58 H4831SC BR2 Win brass); exceeded the 3K+ FPS but group opens up. Have a few more powders to test on. :p

Yowza--that's some fast big bullets! Is a common 270 barrel able to stabilize them OK?

Matrix recommends 1:8 for the 175 and 1:9 for the 165 for stabiliztion. However, depending elevation, some end users are claiming 1:10 stabilization.
