Ron Spomer starts his recent podcast episode with the question that never seems to die, the one he calls the “1,000-pound gorilla in the room”: which rifle cartridge has taken the most deer over the last 150 years, not in theory, but in the real world where hunters actually buy rifles, show up in the woods, and fill tags.
Griffin, Ron’s co-host on Ron Spomer Outdoors, frames the mission in plain language: ignore the “new and biggest and best” chatter, and figure out what has actually killed the most deer in history, even if the answer isn’t trendy or exciting.
Right away, Ron and Griffin also set a boundary that matters. Griffin admits there is no master spreadsheet of “deer killed by cartridge,” and the video’s own disclaimer says these rankings are based on long-term usage patterns like hunter surveys, ammunition production, rifle sales, and field performance, not a mythical perfect record.
That’s a refreshing way to do a topic that usually turns into people yelling caliber names like sports teams. Ron’s approach is basically: if you want the truth, you look at what stuck around, what got bought for generations, and what ordinary hunters could shoot well, year after year.
What “Deadliest” Means In The Real World
A big point Ron makes early is that “deadliest” in deer hunting doesn’t mean the most explosive, the fastest, or the one that looks coolest on a ballistics chart.
In his view, the deadliest cartridge is the one that consistently works, gets carried by huge numbers of hunters, and has been doing it long enough that the decades pile up.
Ron stresses two filters that beat marketing every time: how long a cartridge has been around, and how popular it stayed during those years. He even uses modern examples like the 6.5 Creedmoor and 7 PRC as cartridges that are hot right now, but simply haven’t existed long enough to compete with old standbys that have been stacking deer since your great-grandfather’s era.
Griffin agrees that popularity drives outcomes, because a cartridge doesn’t kill deer sitting in a warehouse; it kills deer when it’s in a rifle that people actually own, can afford to feed, and can shoot without flinching.
And that last part—shootability—keeps coming up. Ron repeatedly circles back to recoil, practical bullet weights, and the kinds of rifles a cartridge was chambered in, because those things decide whether a cartridge becomes a “everyone has one” deer round or a niche favorite.
The Top Five Based On Long-Term Use
Before Griffin reveals his researched list, Ron walks through his own “thinking cap” process, and it’s surprisingly grounded. He’s not trying to crown a magic death ray; he’s trying to name the cartridges that lived in the mainstream long enough to rack up staggering totals.
When Griffin finally gives his top five, Ron says all five were on the table in their discussion, and the final order ends up matching the “grandpa’s rifle” logic that so many hunters quietly live by.
Number 5: .243 Winchester.
Griffin says his research puts the .243 at number five, and Ron doesn’t sound shocked at all. Ron notes how the .243 has been a go-to for youth hunters and recoil-sensitive shooters for decades, and Griffin backs that vibe up by saying it’s still “pretty up there” even today.
The hidden strength here is that the .243 doesn’t punish people. Hunters who shoot it well tend to place shots well, and it’s been common enough—since the mid-1950s—that it had time to become a default option in many families.
Number 4: .308 Winchester.
Griffin places the .308 at number four and ties it to the same engine that fueled other mega-popular cartridges: wide rifle availability, lots of ammunition, and a reputation for doing more than one job.
Ron points out the .308’s timeline matters—it’s newer than the early classics—but he also acknowledges it built momentum and became a modern standard, helped along by its military connection and the sheer number of rifles chambered for it.
Number 3: .30-06 Springfield.
Ron calls it “Papa .30-06,” and his explanation is basically a history lesson that doubles as a hunting lesson. He talks about how many soldiers learned to shoot with it, came home, and already trusted it, plus the flood of surplus rifles that made it accessible for regular people who wanted to hunt.
Ron also likes that it wasn’t trapped in a single rifle style; he mentions it being available in multiple actions, which matters because the more formats a cartridge appears in, the more hunters end up using it.
Number 2: .270 Winchester.
Ron makes a strong case for why the .270 has stayed so loved since 1925: it hits a sweet spot where recoil isn’t nasty, performance is dependable, and bullet weights in the 130–150 grain range are more than enough for deer when used correctly.
He also points out that it wasn’t just a “wide-open West” mule deer round. Ron argues it worked in the East too, especially because it was offered in not just bolt guns, but also pump actions and autoloaders, which were popular in heavily wooded states.
Number 1: .30-30 Winchester.
Griffin’s list lands on the answer many hunters expect, and Ron basically nods like, “Yep, that tracks.” Ron says the .30-30’s biggest advantage is time—dating back to the 1890s—and the way it rode the wave of lever-action popularity for decades when deer hunting was exploding across America.
Ron explains how the .30-30 became “grandpa’s gun” early, and once a cartridge becomes the default in family rifles, it can dominate for generations even as “better” options come along. The .30-30 didn’t need to win every argument; it just needed to keep showing up in the woods, year after year, in the hands of millions.
The Uncomfortable Twist Ron Wouldn’t Ignore
Even after crowning the .30-30 as the sporting-world champion, Ron throws a curveball that Griffin immediately understands: Ron suspects the cartridge that has killed the greatest number of deer overall might be the .22 Long Rifle, not because it’s a good deer cartridge, but because it has been used illegally by poachers in ways that rarely get recorded.
Ron is careful to label it as “slightly illegal,” and he and Griffin make the point that poaching is difficult to quantify because so much of it goes unreported and unsolved, especially when wildlife officers have massive areas to patrol with limited staffing.
It’s worth saying plainly, though: even discussing that reality should never be taken as encouragement. Ron’s point is about numbers and hidden behavior, not ethics or technique, and the ethical line in hunting is supposed to be bright for a reason—fair chase and humane practices are the whole foundation of the tradition.
What makes this section valuable is that Ron is honest about how messy reality can be while still steering the conversation back to legitimate hunting cartridges, which is where the list belongs.
The Rounds Climbing The Modern Rankings
Ron and Griffin don’t treat the top five like a museum exhibit. They talk about what might change if you only counted the last 20 years, and Ron says the .30-30 has likely “lost a lot of ground” with younger hunters who are drawn to newer cartridges and modern rifle platforms.
Ron highlights the 6.5 Creedmoor as a perfect example of a cartridge that became wildly popular fast, almost like everyone decided it was “magical,” even though Ron argues plenty of cartridges have been doing similar work for a long time. Still, he doesn’t root against it; he just questions whether it’s a lasting standard or a fading trend.
Griffin also brings up the influence of AR-style rifles, and that’s where Ron starts talking about the .223 Remington as a cartridge “worth watching,” because it’s easy to shoot, low recoil, and increasingly used in certain places where it’s legal and practical.
He also connects it back to the “cheap ammo and tons of rifles” effect that helped cartridges like the .30-06 and .308 spread.
This is the part that feels most like a real-world forecast: the future “most-used” deer cartridge might not be the most powerful, but the one that fits the rifles people are buying now, and the one they can afford to practice with.
Ron And Griffin’s Bottom Line: It’s The Bullet And The Shot
Ron wraps the whole debate with a statement that cuts through caliber tribalism: it’s about the bullet and where you put it. He tells viewers that most centerfire cartridges can work on deer with the right bullet and good placement, and Griffin echoes that idea without trying to overcomplicate it.
That’s the most important “anti-hype” message in the entire episode, because it forces the conversation back to responsibility. The deadliest deer cartridge, in practice, is the one a hunter can shoot accurately under pressure, the one they’ve practiced with, and the one loaded with a bullet that performs well in the real world.
And honestly, that’s why Ron and Griffin’s top five makes sense even if it isn’t flashy. The .30-30, .270, .30-06, .308, and .243 aren’t just cartridges; they’re habits, hand-me-down rifles, familiar recoil levels, and decades of hunters choosing what works instead of what’s trending.
When you strip away the ads, the bragging, and the online arguments, Ron Spomer Outdoors ends up delivering a pretty grounded verdict: history, practicality, and shot placement have killed more deer than hype ever will.
