Hardest hitting 6.5CM factory round?

I am a long time 30-06 lover. Of all the whitetails I have taken with a rifle, all but one have been with a 30-06 (.308 win was the outlier). Of the 20 or so whitetails I have taken with a rifle, I can only think of 2-3 that didn’t drop in their tracks. (I usually take high shoulder shots because I feel I can ethically take a deer and deliver instant lights out effect)

I just purchased a new Winchester Extreme Weather 6.5. What factory round has delivered similar results for you guys? Can I expect similar results?
 
Here's a little light reading


Edit: I guess shift+enter hits post reply! Meant to add more.

Between myself and a couple buddies we have 6 kills on black bear and mule deer with the 143 ELD-X. It performed well 100 yard to 350 yards or so. Before I had a chrono so no accurate impact velocities to report.

My two bucks it caught spine so DRT. Others ran sub 50 yards. Time to expiration under two minutes on all of them.

Most were before I started taking necropsy photos, but here's last year's buck. Caught against offside hide. Would have appreciated a blood trail for him as he rolled 400' of vert into the canyon. Other animals were no problem to find, some had exits/blood trails.

Check out the thread above for more info on the 140 ELD-M, 147 ELD-M, 130 TMK, Bergers, etc.

Lots of good info there. Thanks for bringing me in the loop. A lot of praise for the 143ELD-X there. I will have to check into factory loadings with that bullet and give them a try for myself. Good place to start.
 
If you’re high shouldering them their dropping in place has nothing to do with the cartridge you’re shooting.

It will probably be more difficult to find a 6.5 load that won’t work than one that will.

My son has used the Hornady 130EldM and 140gr Nosler Solid Base to great effect out of his 260. 129 Winchester Power Points gave great results as well.
 
If you like high shoulder shots, just keep doing the same thing with the 6.5cm. Your shot placement is what is causing the "drt" effect, not your caliber/cartridge/load.

Good to know. I have hunted my whole life, so it feels silly asking a question about rifle shot placement. But never shot a deer with any rifle besides a 30-06, which always felt like a howitzer in my hands. Wasn't sure entirely what to expect with the 6.5. Thanks for the advice.

The good ol' '06 is dang near a howitzer these days, lol. The 6.5cm is a great round for deer, and pretty much anything else you want to hunt. Lots more fun to shoot than a 30-06 also. Tons of info in the 6.5 thread linked above, about bullets, shot placement, and terminal performance. Just pick something in the 130-140 gr range that shoots good out of your rifle, buy a bunch, and kill stuff! Hornady eldm/eldx, sierra tmks, Winchester deer season xp, federal terminal ascent, I'm sure there's more that will also work well.

It’s all good brother.
Here’s a shot placement diagram from my daughters hunters ed class this last summer, both spots drop deer effectively:

I’m partial to the 130gr TMK and ELDM from short 6.5cm barrels. Both will have plenty of juice at any range you might want to hunt at.
 
Give the 147gn eldm a try. It has become my go to round for bears.
The thread Steve attached above showed lots of folks praising the ELD-X and ELD-M offerings. I will be looking into those.

Thanks for everyone’s input. Good to know I should have a really effective hunting rifle on my hands. I wanted to try something new, but it was an uncomfortable thought for me to go after a cartridge with a little less KE than the ‘06. Sounds like I made a fine decision based on everyone’s experience here. Can’t wait to try it out.

You have a great cartridge.

Don’t look at KE alone, because the KE of a solid copper bullet transfers less energy and does less tissue damage than a bonded mushrooming bullet, and significantly less than a highly fragmenting bullet like the SST, ELDm, TMK, Berger.

Search for a thread “.223 for bear, moose, elk” or something like that and look at the thousands of pictures of wound cavities. Then, tell me if you would rather get shot through the shoulder with a cooper bullet that expands little and passes through or with a highly fragmenting bullet.

Summary, bullet construction matters more than KE or bullet diameter/weight.

There are plenty of videos out there showing elk, moose, deer, caribou, and other critters being shot with 6mm and 22 Creedmoor highly fragmenting bullets as well.

There is also a thread on “match bullets” and why they are effective. You can read both sides of the argument but note which side talks about effectively killing vs much of the old myths. Silly myths, especially about “tough rutted up elk shoulders” that are like armor. Hint, they are not— shoulder blades are super thin and living bone is not as hard as the dried bones we see laying around that dry out. A bone is not stopping a rifle bullet. If anything, it usually creates even more shrapnel and damage with bone chunks flying too.

Hit an animal in the vitals, and all that tissue damage results in the fastest blood loss possible and the quickest death —other than a central nervous system shot that is an off switch.

We live in a golden age of manufacturing and technology to see huge sample sizes rather than relying on dudes in deer camp or the gun writers who regurgitate old myths and get paid for promoting stuff.
