In a recent video on Ron Spomer Outdoors, veteran gun writer Ron Spomer and his editor Griffin sat down to talk about cartridges almost nobody talks about anymore.
Not the hot new 6.5 something, not the latest “Creedmoor of the month,” but five quiet workhorse rounds that just keep killing game cleanly without hype or social media buzz.
Their list came from a funny place too.
Griffin told viewers he actually asked AI what the most underrated hunting cartridges were, then handed that list to Ron to react to. Shockingly, Ron said he didn’t just tolerate the list – he agreed with most of it.
Why Great Cartridges Get Ignored
Throughout the conversation, Ron and Griffin keep coming back to one theme: marketing and fashion push cartridges up and down, but performance in the field really hasn’t changed much.
Ron reminds viewers that a cartridge is just a container for powder and a bullet. Shape and name don’t magically kill animals. Velocity, bullet construction, and where you place the shot do.
Griffin adds that a lot of hunters simply overthink everything.
They chase numbers, trends, and buzzwords, while ignoring older rounds that do the same job with less recoil, less blast, and more history behind them.
That’s where this list lives – cartridges that aren’t new or flashy, but still absolutely deadly on deer, elk, moose, and even big bears when loaded right.
Short-Action Sleepers: .338 Federal And 7mm-08 Remington
At number five on the AI list, Griffin reveals the .338 Federal.
Ron lights up immediately. He says he’s “long been kind of peeved” that people don’t appreciate how good this round really is.
As Ron explains, the .338 Federal is just the .308 Winchester case necked up to take a .338 bullet. Same efficient short-action case, just a wider projectile.
He points out that it pushes heavy bullets at velocities comparable to the .30-06, and he’s personally taken a branch-antler bull elk and a big interior Alaskan grizzly with it using stout 185–225 grain bullets.
Close- to medium-range, especially in timber, Ron says it hits like a hammer without the recoil of a magnum.
Griffin notes that AI described it as “heavy bullet performance in a short-action package,” and “perfect for close to medium range hunting, especially in thick timber, but rarely talked about.” Ron agrees completely.
Then Griffin goes to number four: 7mm-08 Remington.
Again, Ron is all-in. He calls it “just about the epitome of the perfect whitetail rifle” for hunters who want less recoil and flatter trajectory than the big thirties.
The 7mm-08 is another .308 case, this time necked down to 7mm. Ron notes you can run bullets from around 100 grains all the way up to around 175, but for most deer hunters, the sweet spot is 140–150 grains.
Griffin shares his own experience: he took his first big game animal, a doe pronghorn, with a handloaded 7mm-08 using a light Hornady SST, and later shot the biggest buck of his life with the same chambering.
AI’s summary, Griffin says, was that 7mm-08 is excellent for deer and elk, has light recoil and great efficiency, but gets overshadowed by newer, flashier rounds in the same 7mm family.
From a practical standpoint, both of these short-action rounds are almost perfect for real-world hunting.
They fit in light, handy rifles, kick less than magnums, and will never notice the difference between “modern hype” and old-school performance when a deer steps out at 200 yards.
35 Whelen: The Overlooked Heavy Hitter
At number three, Griffin reads out AI’s next pick: .35 Whelen (the transcript mangles the name, but Ron is clearly talking about the classic .35).
Here, Ron explains that you start with the .30-06 case again, but this time you neck it up to .358 caliber. That gives you the same powder capacity, just a wider, heavier bullet.
He describes the .35 Whelen as living in the same ballpark as the .338 Federal, but with even heavier bullet options. You can run 225–250 grain bullets comfortably, and there are 300-grain bullets out there for those who really want penetration.
Ron says it has become a sort of “sleeper” choice for moose, elk, bears, and even big brown or grizzly bears, especially for hunters who want serious punch without the recoil and blast of something like a .375 H&H.
AI, according to Griffin, called it a “powerhouse for moose, elk, and bears” that still fits a standard .30-06-length action and is “overshadowed by magnums but very versatile.”
Ron adds some history too.
He notes that the concept dates back to the early 1920s, often credited to Colonel Whelen and his circle, and that it stayed a wildcat for decades before finally being standardized in the late 1980s.
From a commentary angle, the .35 Whelen really represents the kind of round a lot of modern hunters are quietly rediscovering.
If you don’t care about shooting 600 yards and just want deep, reliable penetration in thick country, it makes a lot more sense than chasing ultra-high BC bullets and giant muzzle brakes.
280 Remington: Better Than Its Reputation
Number two on the list is .280 Remington, another cartridge Ron has championed for years.
He explains that it’s simply the .30-06 case necked down to 7mm (.284), giving you higher sectional density and more bullet weight range than the .270 Winchester.
The problem, as Ron tells it, is timing. The .270 Winchester showed up first and became a legend. The .280 arrived in the late 1950s as Remington’s attempt to compete, and it never really shook the “me too” label.
Ballistically, Ron argues, you can make a solid case that the .280 is actually superior to the .270.
You can run heavier bullets up to 175 grains, still have flat trajectory, and enjoy moderate recoil in a standard-action rifle.
Griffin points out that AI described the .280 as “ballistically fantastic,” bridging the gap between the .270 and .30-06, and noted that the .280 Ackley Improved version can get near-magnum performance with only a bit more velocity and pressure.
Griffin owns a .280 Ackley himself and says he “loves it to death,” using it for all sorts of game.
He also mentions that one neat perk is you can fire standard .280 Remington factory ammo in a properly cut .280 Ackley chamber, getting usable performance while also fire-forming brass.
In practical terms, the .280 sits in that sweet spot so many hunters say they want: flat-shooting, enough bullet weight for elk, and recoil most people can manage without flinching.
The only real reason it’s not more popular is simple – it isn’t new, and it doesn’t have a heavy marketing push behind it.
257 Roberts: The Gentle Deer Killer That Won’t Die
Finally, Griffin unveils AI’s number one underrated hunting cartridge: .257 Roberts.
Ron laughs and says many hunters will not only be surprised, they’ll be confused: “What is that?”
He explains that the .257 Roberts is based on the 7×57 Mauser case necked down to .25 caliber. It came along after the .250-3000 Savage and was considered a fast, efficient, dual-purpose round for both varmints and deer.
Ron notes that with 100-grain bullets it could hit around 3,000 feet per second for its day, and it built a strong reputation with whitetail hunters who also wanted to shoot coyotes, rock chucks, and groundhogs.
Griffin shares a family story: his dad once shot what he called the biggest buck of his life “square in the chest” with a .257 Roberts and claims the deer ran off, leading him to sell the rifle.
Ron gently suggests that was probably more of a bullet-choice or shot-placement issue than a cartridge failure.
He points out that plenty of game has been taken cleanly with even smaller rounds like the .243 Winchester, and there’s no reason a good 100–120 grain .25-caliber bullet can’t do the job on deer.
According to Griffin, AI described the .257 Roberts as “soft shooting, flat trajectory, excellent for deer and pronghorn, but overlooked due to age and lack of marketing.”
Ron jokes that this description sounds a lot like him: older, effective, but not exactly hyped anymore.
From today’s perspective, the .257 Roberts is a perfect example of what gets lost when the industry chases the next big thing.
For a recoil-shy hunter, or someone introducing a new shooter to centerfire rifles, it’s almost ideal – gentle on the shoulder, deadly on deer-sized game, and a lot more interesting than just copying whatever everyone else is buying.
It’s Not The Name On The Barrel – It’s What You Do With It
By the end of the video, Ron and Griffin both emphasize that all of this is opinion and context.
There are no “loser cartridges,” only mismatched expectations, bad bullets, or bad shooting.
Ron stresses that if two cartridges launch bullets with the same ballistic coefficient at the same muzzle velocity, their trajectory will be essentially identical, regardless of the name stamped on the case.
You might get more energy from a heavier bullet, but gravity and wind don’t care about marketing.
Griffin adds that too many hunters obsess about the headstamp instead of asking honest questions: what ranges do I really shoot? What animals am I really hunting? How much recoil do I actually want to deal with?
The five rounds highlighted in Ron Spomer Outdoors — .338 Federal, 7mm-08 Remington, .35 Whelen, .280 Remington, and .257 Roberts — all answer those questions in very practical ways.
They aren’t trendy.
They just work.
And as Ron and Griffin both hint, once you actually hunt with some of these “underrated” cartridges, you may find yourself wondering why you ever bothered with anything else.
