The Ruger No. 1 is one of those rifles that turns a hunt into an occasion. Its sleek single-shot profile, strong action, and classic lines invite careful shooting, but the chambering matters if you want beauty and usefulness in the same package. These seven picks stand out as the ones that still make honest hunting sense today.
.243 Winchester
If you want a Ruger No. 1 that feels light, lively, and easy to place precisely, the .243 Winchester is hard to dismiss. It is one of the friendliest chamberings for newer shooters, but that does not make it a lightweight in the deer woods. With the right bullet, it is perfectly capable on whitetails, pronghorn, and similar game.
In a single-shot rifle, the .243 plays to precision and discipline. It encourages shot placement over brute force, which fits the No. 1 personality beautifully. Recoil stays mild enough for long range sessions, and that usually means better field confidence when the moment of truth arrives.
For open country deer and antelope, this is a very sensible match.
.257 Roberts
The .257 Roberts has always carried a little romance, and in a Ruger No. 1 it feels right at home. This is the kind of chambering that appeals to hunters who appreciate old-school balance, modest recoil, and enough authority for deer-sized game without unnecessary noise and punishment.
What makes the Roberts special is how elegantly it handles common hunting chores. It shoots flat enough for practical distances, hits harder than its gentle manners suggest, and tends to leave shooters smiling after a long day at the range. That combination is not easy to find.
For someone who values tradition as much as effectiveness, this pairing is genuinely charming and still very useful.
6.5 Creedmoor
Some purists may prefer older cartridges in the Ruger No. 1, but the 6.5 Creedmoor earns its place through pure practicality. It is accurate, widely available, easy to load for, and effective on deer, antelope, feral hogs, and similar game. In other words, it brings modern convenience to a very classic rifle.
The round also complements the single-shot format better than critics might expect. Good external ballistics make first-shot precision easier at longer distances, which is exactly where the No. 1 demands discipline. You are not spraying follow-up shots anyway, so a cartridge built around clean, efficient performance makes a lot of sense.
This is the choice for hunters who want classic style without giving up current ballistic advantages.
.270 Winchester
Few cartridges have a stronger claim to all-around hunting utility than the .270 Winchester. In a Ruger No. 1, it becomes a trim, handsome rifle that can handle everything from mule deer and whitetails to sheep, black bear, and elk with proper bullets and sensible distances.
Part of the .270’s long-running appeal is that it simply does many things well. It shoots flat, recoils less than larger .30-caliber options, and has a deep bench of hunting loads behind it. That makes it easy to trust whether you are in hardwoods, farm country, or open mountain terrain.
If you only planned to own one No. 1 for North American hunting, this chambering would deserve a long, serious look.
.30-06 Springfield
There is no mystery to the .30-06 Springfield, and that is exactly the point. It remains one of the most versatile hunting cartridges ever made, and the Ruger No. 1 gives it a little extra character. Together, they create a rifle that feels both deeply traditional and thoroughly capable.
The .30-06 covers an enormous spread of game and bullet weights with ease. From deer and hogs to elk and moose, it offers practical flexibility that few chamberings can match. In a single-shot rifle, that confidence matters, because you want a cartridge that can do serious work when the first shot is the only one that counts.
For hunters who value proven results over trendiness, this is still one of the smartest picks on the rack.
7mm Remington Magnum
The 7mm Remington Magnum gives the Ruger No. 1 a little more reach and authority without crossing into truly punishing territory. For hunters who spend time in canyons, alpine country, or big western basins, that blend of flat trajectory and strong terminal performance is easy to appreciate.
This is not the chambering for everyone, especially if recoil sensitivity shapes your choices. But in a rifle built around deliberate, well-aimed shots, the 7mm magnum shines. It carries energy well, resists wind better than many older favorites, and remains a strong option for deer, elk, and similar game at longer distances.
When the landscape opens up, this pairing starts to look especially compelling.
.375 H&H Magnum
A Ruger No. 1 in .375 H&H Magnum is not an everyday deer rifle, and it does not pretend to be. What it offers is serious big-game credibility in a classic, compact package. For large bears, moose in thick country, or African plains game and heavier pursuits where legal and appropriate, this chambering gives the rifle real gravitas.
The .375 H&H has survived for generations because it works across a surprisingly broad spectrum. It hits hard, penetrates deeply, and still carries a reputation for manageable field performance compared with even larger dangerous-game rounds. In a strong falling-block action, it feels purposeful rather than excessive.
For hunters chasing genuinely big animals, this is where the No. 1 becomes more than elegant. It becomes formidable.
