A few days into the late-season cow elk hunt here in Utah in 2018, my buddy Chad and I sat around his kitchen table. Chad’s brother Clint was on the phone, which lay on the table between us.
You’re trying to kill an elk with a .308?” Clint’s voice garbled from the phone.
I nodded, even though he couldn’t see me. “Yeah. Why?”
Clint sighed. “That’s just not enough bullet to kill an elk.”
I glanced at Chad. Between the two brothers, I reckon they’ve harvested north of 80 elk in their forty-odd years of hunting together. If anyone knows elk hunting, it’s Chad and Clint.
“Well what should I shoot?” I asked Clint.
“You can borrow my 7mm Remington Ultra Mag,” Clint said.
I raised my eyebrows at Chad. A 7mm Remington Ultra Mag felt like overkill for a cow elk, especially with how well I’d closed the distance on elk so far. If everything went according to plan, I wouldn’t need to shoot past 300 yards.
A week or so after that conversation with Clint, I shot my cow elk at 400 yards with Chad’s old Ruger .270 Winchester. She dropped with one shot.
Now, as I while away the rest of winter waiting for pre-runoff fly fishing and turkey season, I’ve thought a lot about that conversation with Clint. Was my .308 really not up to snuff for elk? Other friends of mine, elk hunters as avid as Chad and Clint, had recommended the .308. My own research supported the .308’s capability.

Richard Mann wrote the following for Petersen’s Hunting regarding the .308:
“It will work splendidly on whitetails – I’ve done that – and it’s sufficient for moose – I’ve done that, too . . . When properly zeroed it will allow to you hold dead on out to just the other side of 300 yards.”
John B. Snow, the Shooting Editor for Outdoor Life, had this to say on the .308:
“It wasn’t that long ago that a .308 Win. would have been considered on the margins as an acceptable elk round, but with improvements to bullet design and cartridge technology, you have no need to worry.”
Well John, I did worry. I worried a lot that my .308 wouldn’t answer the call for 2019, so I sold it for a Weatherby Vanguard Sporter .270. What’s really interesting, though, is that while I spent hours and hours deciding between a .270 or a .25-06, just about every article I read comparing the two cartridges agreed on at least one thing.
Any reasonable bullet – from the .25-06, 6.5 Creedmoor, .270, and yes, the .308 – will knock down an elk if that bullet hits true through the vitals. Remember, I took my elk last season with one shot from a .270.
That naturally brings up the question hunters have debated for millennia (I’m sure our cavemen ancestors argued over which arrowheads were better for saber-toothed tigers – a sobering thought). Does your cartridge or shot placement matter more when it comes to cleanly killing big game like elk?
Shot placement has the edge in my book – call it 70% shot placement, and 30% cartridge type. The consensus from articles I’ve read and hunters I’ve talked to is that any round using the .30-06 as its parent cartridge (as the .270 and .25-06 do) is a reasonable baseline for adequate elk-killing ammo. The 6.5 Creedmoor was built by modifying a .30 Thompson Center case to handle .264 bullets.
As long as you’re using a bullet with enough foot-pounds of force at 300 yards, the bullet you shoot doesn’t really matter when it comes to killing elk. Shot placement matters far more. A 7mm Remington Ultra Mag will punch through damn near anything, but it’s not likely to kill an elk if you shoot it in the hindquarters instead of the vitals.
Perhaps Bryce Towsley said it best in a 2010 article for American Hunter.
“First off, I know all too well that elk can and have been killed with little cartridges. I also know there are stories of at least one elephant being killed with a .22 Long Rifle, but no sane person will argue that the .22 LR is an adequate elephant cartridge.”
That elephant story sounds like more of a fisherman’s tale to me, but Towsley gets to the heart of the matter here – if you put an appropriate bullet in the right place, you’ll bag your game.

The debate around the “best” elk cartridge, I think, has more to do with where and how you hunt than the round’s actual knockdown power.
Do you agree or disagree? Let me know in the comments.
My 25-06 is the only rifle I hunt "big" game with... I haven't got my elk yet, but my mule deer didn't move at 310 yards. She was quarted away and I managed to hit high in the back of the lungs and tumble the bullet into her spine. I'm confident it'll take an elk.
Shot placement is most important to me, at the same time if you are shooting too small of a caliber there is no room for error. If you double lung an elk with a 243 it is likely to travel farther than if you double lung an elk with a 300, and that could possibly change the outcome of your hunt
I have been hunting and guiding elk since 1985. Most guys that shoot those big magnum cartridges don't shoot them very well. They are afraid of the recoil. Too many hunters do not take their hunt as seriously as I think they should. There is no substitute for practice. I have many hunters ask me what gun they should bring on their elk hunt and I tell them "bring the gun you shoot the best". Shoot the best premium bullet you can shoot and start practicing. I've only been on about 150 elk kills and I am sure not as many as some on this post but the guy that shoot his gun accurately brings home the game. Shot placement is key. Another part of accurate shooting is patience. Patience will put more animals in your freezer. Happy hunting!!
Many Elk were killed with the old 257 Roberts. It is all about shot placement and knowing the capabilities of your rifle. All one needs is an accurate rifle and a little common sense.
I think you help yourself w a magnum cartridge gor elk. Sure smallers will do it but i think you are better served with heavier bullets at higher velocity. I use a 300 RUM. Pretty good performance with a 180 grn bonded bullet.
I shot a late season cow this year with my 300win mag in Montana. Watched it for a long time, showed no sign injury. While butchering i found what i guess to be a 243 bullet in its front shoulder blade. There was no bone breakage at all and only a little damaged/brused meat. Dont leave it to a perfect shot, use enough bullet to do the job. Have respect for the animal.
Hard to take seriously an author who questions whether the .308 is enough of a cartridge, especially when he then tells us that a .270 is. If you compare the ballistics for the 180 grain Trophy Bonded Tip from Federal in .308 with any .270 cartridge (including 130, 140, and 150 grain bullets), the .308 delivers more energy on target at any distance.
I have used my Steyr scout chambered in .308 using a 180-grain Trophy Bonded Tip from Federal for over 20 years, and killed everything including elk, kudu, and tougher animals like zebra, giraffe, etc. etc. We're not talking fancy shooting, just good old heart-lung minute-of-pie-plate accuracy. Any author who questions the ability of a .308 to begin with, and then tells us that a smaller, lighter bullet is perfect, has no credibility.
The primary question is, do you want to be a hunter or a long range animal killer. Game beyond 400 yards has no clue that you are in the same county and all of his natural skills to avoid you are negated. If you are a hunter and are able to stalk in within reasonable killing range, which to me means, well within 400 yards, then you do not need a magnum round in order to cleanly kill.
At age 76, I long ago lost count on deer that I have killed. Elk? Only two bulls. One at just over 300 yards with a 30-06 and the most recent in Dec. 2016, using a 280Rem. at 280 yardsI
Spot the game and get within clean killing range while using a cartridge equal to or more powerful than 270Win. but not a magnum. Less than .277 lacks a wide enough killing channel. If you feel confident to make a neck shot, do it. Otherwise shoot into the heart/lung area. The animal may not fall right away, but he will not go far. Above all, show your love for the game and give them a clean, quick kill. Steven
I believe in shot placement is key to any successfull hunt if you can't hit the vitals out to 300 yards then you need practice calliber is not as inportant as shot placement I hunt with 7mm-08 150 bt works every time.
Shot placement is the main fact on clean and humane kills. I have used .270 and 6.5 CM to kill all my elk with 1shot kills from 60 to 512 yards.
I have not missed an elk season in Colorado in over 40 years. I have guided elk hunters for over 10 years. I own and operate Coulter Lake Outfitters in Rifle, Colorado. Any good caliber rifle, .243 and up will kill elk if the shot placement is right. Be familiar with your gun at all ranges. Know what it will do. My son shot his first elk (6x6 bull) with a .243, well placed one shot. I have seen hunters shoot elk with 300s, 338s, ect. and have to shoot them several times because the shot placement was wrong.
SHOT PLASEMENT IS #1
Be familiar with your gun and what it does.
Stay within your comfortable shooting distance.
I've guided elk hunters for over 25 years and have hunted them longer. In my family, the first gun any of the younger generations were allowed to use was a .243. It was dead on and put meat on the table everytime it was hit right. I've harvested many elk - bulls too - with a variety of calibers including 30-30, 30.06, .270, 7mm Rem Mag, .308, etc. You put the shot on mark and the feeezer is filled. Bad shots with a .308 or a .338 won't produce any more animals for one vs. the other. Sure you might get lucky taking the shoulders out but then again if your shooting for shoulders, you don't like elk meat. My current go to is a 7mm Rem Mag with a 150g BTSP. It's big country with shots typically over 375yds. Shot Placement.
Every hunter/marksman is unique in his own way. If a guy shoots his weapon well and knows his ballistics he can pull off things ethically on big game at long range. The hunter that shoots 20 rounds or less a year out of his hunting rifle needs to accept that he cannot do what the other guy is capable of and to help himself might need some help with larger caliber rounds. Then you talk about being able to handle the recoil of these different calibers. There are those that can and those that flinch easily! Moral, shoot more and know your abilities and your cartidges abilities. Thats an ethical hunter doing his job!
Ft. Lbs. of energy is critical and it can only be transferred with the correct bullet construction. As far as magnum and non magnum goes you need to follow your minute of angle rule. If the best you can shoot with your magnum is 2 in. At 100 yards, you are limited to about 300 yards to stay in a kill zone. If you can shoot a 1/2 in. Group with your non magnum you can stay in the kill zone out to the point your ft. Lbs. of energy drops below the 1200 ft. Lbs. all of this comes down to knowing your equipment. Accuracy,bullet construction or performance range and velocity.
Since most of the biggest bulls are taken with a bow these days, I would say that knocking a bull off it's feet is not a requirement. The problem is that there is a lot of range between the best possible shot and the worst, and shots can be from 10 yards to half a mile (if you believe the talk). Without knowing your load, the .270 will in most cases shoot flatter, but the .308 will carry more energy at distance. The differences are not large, and this is not a question we can answer that precisely, so I argue that in a practical sense, they are the same.
I really think it's the largest cartridge you can shoot accurately. Some might be a .300 RUM some might be a Creedmoor, but placing the shot is king!!
I've seen elk shot with lots of big calibers, and some with smaller caliber. A good bullet with a good ballistic coefficient placed in the correct spot will kill any animal. Knowing your rifle and being able to hit your mark every time is the key to success!
Shot placement is most important, but it can't hurt to have a little knock down power. That's why I use a 300 mag.
