This story features a unique, American-designed rimfire rifle, chambered for the potent .17 HMR round. The current generation Browning T-Bolt has a tang-mounted ambidextrous safety, a choice of barrel contours, lengths, and finishes, and a variety of stock options. What sets the T-Bolt apart from other rimfire rifles is the way the action cycles. There is not a conventional bolt that requires four distinct motions (lift bolt handle up/pull back/move forward/rotate handle down). With the T-Bolt you simply pull the handle straight back to extract a round, then return it forward to chamber a new round from the Double Helix magazine. The cocking effort is divided between back pull and forward movement so the effort is relatively light and easy.
Among current rimfire rifles, the Browning T-Bolt ranks high for fit and finish. The bluing is very nice and the T-Bolt even boasts a gold-plated trigger shoe. Many different stock types have been offered in recent years including some very nice AA Maple stock models as shown below (click to zoom). These T-Bolt rifles exhibit very fine craftmanship. Current models are made in Japan under license to Browning.

T-Bolt Owner Talks about Function and Accuracy
“I have a Browning T-bolt in .17 HMR, but with the maple stock. It is probably my favorite .17 HMR rifle (also the most expensive). The rifle feels smaller than some of my other .17 HMR rifles. I think the length of pull is a little shorter. I do like the light weight and trim handling of the rifle and the straight-pull bolt can be cycled really quickly. Mine is quite accurate and will shoot one-inch groups at 100 yards with both Hornady ammo and the CCI A17 ammo.” — RexRay, Varminter.com Forum member.
Pros and Cons of the Browning T-Bolt
The T-Bolt has a reputation for good accuracy, provided you have a good lot of .17 HMR ammo (we recommend checking for bullet run-out before you shoot for groups). The straight-pull action works as advertised — it is fast, smooth, and easy-to-operate. The Double Helix magazine (covered below) is excellent. It is very compact yet ultra-reliable. Another plus is that the T-Bolt has been produced in many different versions, with a variety of stocks, and even a stainless action version.
What are the negatives? Some of the stocks have a somewhat short length-of-pull, but this is easily solved with spacers. The main complaint is the factory trigger — some owners say it is too heavy at about 4 pounds, though the break is clean. For varmint work, we could live with the stock trigger and put money saved into optics.
If you prefer a very light trigger, JARD makes a T-Bolt replacement trigger. Featuring an aluminum housing, the JARD T-Bolt trigger can be ordered with 12-, 16-, or 20-ounce pull weights. The JARD trigger offers a crisp, clean break significantly lighter than stock. But at $254.95 the JARD trigger is fairly expensive. Additionally there have been a couple complaints about slam fires at the lowest weights so we recommend the 20-ounce. Here is one owner review, from a Rimfire Central thread: “The new Browning T-Bolt is a great rifle in all aspects except for the trigger. In my case when I received my JARD trigger it was an almost drop-in installation with very little adjusting or fooling around. For me it made a decent little rifle a great little rifle.”
Browning Double Helix 10-Round Magazine
The T-Bolt’s patented 10-round rotary Double Helix™ magazine is a unique design that feeds very reliably and is easy to load. The Double Helix magazine uses a torsion drive spring and interlocking gear design to maintain correct timing and exact cartridge alignment for smooth, reliable feeding. The translucent gray body allows for easy verification of the number of remaining cartridges. We like the fact that the Double Helix provides TEN-round capacity while fitting nearly flush with the bottom of the action.
The Browning Double Helix rotary box magazine system is easy to load, easy to carry, and easy to use. The smooth, rounded exterior contours of the Double Helix, along with twin gripping grooves, tapered shape and a slightly extended baseplate design make insertion positive, while the spring-assisted drop-free magazine ejection feature allows for rapid magazine changes. T-bolt owners confirm that feeding and reliability is excellent — the magazine design puts cartridges in perfect alignment with the chamber.
Other Browning T-Bolt Variants
In recent years, Browning has produced T-Bolt rifles in a variety of models, with many different stock types and various barrel lengths/contours. Most of the photos above showcase the AA Maple Sporter T-Bolt, which is currently out of production, though still available from some dealers (if you search). We like the looks of the AA Maple T-Bolt, but there many other stock options including dark brown, Black, Green, and various camouflage finishes. Use the links below to see other T-Bolt configurations.
Current production T-Bolts are offered in four rimfire chamberings: .17 HMR, .22 LR, .22 Magnum, and .22 WMR. Barrel contours and lengths (from 2″ to 22″) vary from model to model. Shown below is the New-for-2024 T-Bolt Target SR (Suppressor Ready) and two other current models. Then we feature five notable discontinued T-Bolt rifle models. CLICK HERE to see all discontinued T-Bolt variants — many of which are still available if you search gun vendors.
.17 HMR Cartridge — Fast and Deadly on Small Varmints
We are big fans of the .17 HMR round. It’s just about perfect for ground squirrels, and is effective on prairie dogs out to about 200 yards. The three main .17 HMR producers have been CCI, Federal, and Hornady, but you will also see Browning and Remington .17 HMR ammo. Choose from 17gr or 20gr bullets — both work well in the varmint fields. A good source for all types of .17 HMR ammo is TargetSports USA.
Here is a Comparison Test of Multiple Types of .17 HMR Ammo
CCI .17 HMR TNT offers 2650 FPS Velocity
For varmint work we like CCI’s modern .17 HMR VNT ammo. This boasts class-leading 2650 FPS muzzle velocity. Engineered to combine good accuracy with high impact energy, this CCI TNT ammo features a 17gr polymer-tipped bullet designed for rapid expansion. We also like the Hornady .17 HMR Varmint Xpress ammo, rated at 2550 FPS with 17gr V-Max bullets.
SUMMARY: Powder can have a very long shelf life. You need to watch for changes in smell and color. A reddish tinge, almost like rust on the powder, is a bad sign, as is a foul odor, not to be confused with a normal chemical smell. Either of these signs indicate it is time to dispose of your powder by means other than shooting.
Ever wondered about the stability of the propellants in your reloading room? There are some important things you should know about powder storage, to ensure consistent powder performance and safety. Western Powders (which has been acquired by Hodgdon) published an informative Q & A series entitled Dear Labby: Questions for our Ballistics Lab . Here are some excerpts that pertain to powder storage and shelf life. Worried that your powder may be too old? Western’s experts explain how to check your propellants for warning signs.
Proper Powder Storage
Q: I live in southern Arizona where it is very hot. I am told powders will become unstable if stored in an area not air-conditioned. My wife says no powder or primers in the house. Can powder be stored in a refrigerator? What about using a fireproof safe? I would appreciate your ideas. — M.C.
Lab Answer: SAAMI guidelines are pretty clear on issues of storage. They recommend storing smokeless powder in containers that will not allow pressure to build if the powder is ignited — ruling out gun safes and refrigerators.
In their original containers, the lifespan of smokeless powders is quite long, even in hot, arid climates. In fact the lifespan is typically longer than the average handloader would need to store them. Stored safely in a garage or outbuilding, your powder should last years. If you see the powder developing a reddish tint, or giving off a foul odor, it is time to discard it.
Clumps in Powder Container
Q: I ordered some of your Accurate 1680 powder back about in December. I just now opened it … and it is full of clumps. My knowledge tells me that means moisture. Am I wrong? I just now broke the seal and it has been stored in a ammo can with desiccant packs around it and a dehumidifier running 14-16 hours a day. I can’t imagine this being my fault, if this does indicate moisture. I don’t know if the pink part on the label is suppose to be red or not, but it is definitely pink, so if it was red I am wondering if I was shipped an old container? I hope that this isn’t bad and I am stuck with it…
Lab Answer: All powder contains a certain amount of moisture. When the powder is stored or during shipping, it can go through temperature cycles. During the cycling, the moisture can be pulled to the surface and cause clumping. Clumping can also be caused by static electricity if too dry or the powder has limited graphite content. You can break up the clumps before metering and they shouldn’t be a problem. This will not affect the powder performance, so your product is fine. Accurate 1680 labels are designed in Pink. As a side note, specification for testing powder is at 70° F and 60% humidity.
Shelf Life and Packaging Dates
Q: Does powder ever get to old to use and what identifying marks does your company put on the canister for when it is made, You have helped me out a while ago when I asked about keeping my cowboy shooting under 950 fps and it works great less stress on the hand and the recoil is very minimum. — R.B.
Lab Answer: On one pound bottles, the number is on the corner in a silver box. If the powder was poured today, it would read 012815 followed by a lot number. The whole number would look something like 012815749. Eight pound bottles have a sticker on the bottom with an obvious date code. The lot number appears above the date.
Do you compete in rimfire benchrest, silhouette, or NRL22 matches? Then you’ll want to check out the Shooting Sports USA .22 LR Ammo Roundup on the SSUSA.org website. That article covers .22 LR ammunition from Lapua, ELEY, SK, RWS, Norma, Wolf, and Aquila. Notably there’s a detailed discussion of Lapua’s new Long Range and Super Long Range ammo. In addition, SSUSA confirms that SK ammo (made in Germany by Nammo, parent of Lapua) and Wolf Match Target ammo (made by ELEY) both offer quite good performance for a moderate price.
The article notes that there is a much wider range of .22 LR ammo types available now than a few years ago. It’s not just a choice between cheap products and high-end match ammo. As SSUSA explains: “It used to be that .22 LR was either quite expensive match grade ammo, or it was cheap plinking or hunting ammo. Today, competitors have choices in grades of .22 LR match ammunition to suit their pocketbook or firearms.” We’ve seen good results with relatively inexpensive Norma Tac-22, and the SSUSA article says that SK performs well above its price level.
Seven Brands of .22 LR MATCH AMMUNITION
Lapua Super Long Range and Long Range .22 LR
Lapua Super Long Range and Long Range ammunition comes from Finland, and is designed for the growing long-range rimfire disciplines with targets at 100-300 yards. Lapua says this ammo delivers very low ES and SD numbers. Our friend F-Class John has tested this ammo and confirmed it performs very well (SEE video above). “Each production lot of Lapua’s new rimfire products are test-fired in 50-round groups for dispersion”, Capstone’s Marketing Director, Geoff Esterline, said. “The results determine whether it makes Super Long Range or Long Range packaging.”
ELEY .22 LR Ammunition
ELEY has long been a top choice for .22 LR competition — both position shooting and benchrest. ELEY now offers 11 different varieties of .22 LR match ammunition, ranging in price from $7 (Benchrest Outlaw) to $20 (ELEY Tenex). If you compete in the rimfire benchrest, you should definitely try some ELEY ammo.
SK .22 LR Ammunition
Numerous .22 LR ammunition types are offered by SK, suitable for a variety of disciplines — from NRL22 to Biathlon. Generally cheaper than ELEY Match ammo, SK offers good “bang for the buck”. F-Class John says it performs great considering the price. The SSUSA article notes that: “German manufacturer SK has eight match-grade .22 LR offerings, including two for pistols, one for semi-automatic rifles, and one for frigid, wintertime conditions.”
RWS .22 LR Ammunition
Sometimes hard to locate at vendors in the USA, RWS is popular among European competition shooters. The top-tier RWS ammo is a choice of many competitive shooters. RWS currently offers nine Premium Line .22 LR varieties and three Professional Line offerings. The SSUSA tester noted that RWS Rifle Match ammo shot great in his Bergara BMR, shooting one-ragged-hole groups at 50 yards and about one MOA at 100 yards. That’s great performance for $10/box ammo.
Norma .22 LR Ammunition
Norma recently introduced XTREME LR-22, a new type of competition rimfire ammo with a radical new bullet. This unique, patented bullet design has a special base with a cone (see diagram). Norma claims that this “rocket tail” design reduces drag by creating less negative pressure at the back end of the bullet. It will be interesting to see how this new bullet design works in rimfire ELR competition.
Wolf .22 LR Ammunition
SSUSA says that Wolf Match Target is a top performer in the under-$10 per box category. This is because, according to SSUSA: “It is manufactured by ELEY in England (and loaded with Vihtavuori powder) and re-branded, if online information is correct.” Wolf Match Target is available from Target Sports USA for $74.99 per thousand ($0.15 per round).
Aguila .22 LR Ammunition
Made in Mexico, Aguila .22 LR rimfire ammo is the bargain item among the seven ammo-makers featured by SSUSA. It is widely available at very affordable prices.
We wouldn’t choose Aguila for a benchrest or three-position match, but it could be more than adequate for a local NRL-22 match or a steel-target competition at relatively short range. Aguila .22 LR ammunition starts at under $3.00 per box. And right now Midsouth offers a 2000-round Case of Aguila for just $114.99. That works out to just $2.87/box or six cents per round.

This story first ran in 2010. But to mark our long-standing friendships with shooter Joe Friedrich and chassis builder Gary Eliseo, we wanted to reprise the article for the new year, with 2024 just hours away. Joe’s Eliseo-chassis 6mmBR rifle delivered some of the most amazing accuracy with factory ammo we’ve ever seen, in any rifle, in any caliber.
Amazing Accuracy from 6mmBR Tubegun
What kind of accuracy do you think a tubegun can deliver with factory ammo — during barrel break-in? Perhaps 0.6″ at 100 yards, half-MOA if the conditions are perfect? Well you may want to change your preconceptions about tubeguns — and factory ammo. This Eliseo R5 repeater, smithed by John Pierce with a Pierce CM action and Broughton 5C barrel, shot the Lapua 90gr factory ammo into flat ONEs during the break-in session. A day later, in tricky 8-14 mph winds, the gun nailed a witnessed and software-measured 0.174″ 5-shot group using the 105gr factory ammo. That would be impressive for a “full-race” benchgun with precision handloads. For an across-the-course rifle shooting factory ammo, it’s pretty amazing.
Eliseo Tubegun Shoots in the Ones
This accurate rifle belongs to our friend (and designated expert trigger-puller) Joe Friedrich. During the initial break-in session, since his reloading dies had not yet arrived, Joe decided to start with some Lapua factory-loaded 6BR ammo he had on hand. After doing a few two-shot-and-clean cycles (with patches and nylon brush), Joe decided to try a 3-round group just to see if the Broughton barrel had some potential. To his astonishment, the Eliseo R5 put three rounds in 0.100″ (photo below left). Joe then cleaned the barrel again, shot a couple foulers and tried a 4-shot group. The results were just as stunning — 4 shots in a mere 0.104″ but three in virtually one hole (photo below right).
You Can’t Believe How This Gun Shoots
Joe called your Editor and said “You can’t believe how this gun shoots with factory ammo!”. So we arranged a photo session for the next afternoon, where I could verify the rifle’s accuracy. Well it turned out the conditions were way more challenging than when Joe broke in the barrel the day before. Winds were running 8-14 mph and were swinging through 180 degrees half-way down the range. Joe fired a few 90s through the Oehler chronograph at my request, then opened a box of Lapua 105gr factory ammo. It took about four rounds for the barrel to settle in after being cleaned the night before. Then Joe got serious, and with your Editor looking over his shoulder, he drilled a 0.174″ five-shot group in switching winds, doping every shot. Joe felt the gun could have shot tighter but he missed one wind call.
Serious Accuracy with a Multi-Purpose Rifle
So there you have it — a tubegun that shoots in the ones with factory ammo. Joe says that, at least with the 90s, the Elesio R5 shoots as well as his 6 PPC. Joe stressed that “steering the tubegun is hard work. You really have to concentrate compared to a purpose-built bench gun like my PPC. With the tubegun, everything has to be perfect on every shot — hand position, cheek position, stock position in the bag. If you’re off just a little bit, it’s easy to steer the gun the wrong way and send a shot out of the group.”
Accuracy Great But Fouling Heavy and ES Could Be Better
Have there been any negatives to Joe’s 6BR tubegun experiment so far? Well, the Broughton 5C barrel, while phenomenally accurate, shows signs of being a bad fouler. Copper built up pretty quickly over the first 25 rounds or so. We saw best accuracy with a recently-cleaned barrel. Hopefully the fouling will lessen as the barrel polishes in with use. And the canted land barrel is slower than average with the factory ammo. Lapua rates its 90gr naked-bullet ammo at 2950 fps with a 26″ tube. In Joe’s 27.5″ barrel we only averaged 2901 fps. With the 105gr factory ammo, which is rated at 2790 fps, we averaged just 2694 fps. That’s quite disappointing. Also the ES on the factory ammo, slightly over 50 fps for both bullet types, wasn’t particularly good. Still, the overall results were stunning. This gun shoots better than many long-range benchrest rifles running carefully-developed handloads — and it does that with factory ammo, right out of the box.
Joe Friedrich is a superb benchrest shooter, who has won many matches and set National Records in ARA rimfire benchrest competition. Here is Joe with “Sweet Pea”, his favorite .22 LR rimfire rig. With over 100,000 rounds through the Benchmark barrel, this well-worn rifle set an ARA 4-target Aggregate record! READ about Sweat Pea Record HERE.
NRA Media offers a series of informative videos about the Science of Shooting, covering a wide range of topics, from eye dominance to long-range ballistics. These videos feature high production values, with super-slow motion segments, as well as helpful computer graphics to illustrate the principles covered.
The videos are narrated by Jessie Harrison, a top action pistol shooter (and the first women ever to achieve USPSA Grand Master status). Jessie is assisted by talented shooters such as Top Shot Season 4 Champion Chris Cheng. There are 40 videos in the Firearm Science Video Series. Here are seven good NRA science videos, with links to others below.
Olympic Gold Medalist Jamie Gray demonstrates the four positions used by competition shooters: Prone, Standing, Sitting, and Kneeling. Helpful overlay graphics show how the human skeleton aligns in each of these positions. This video should help hunters as well as competitive position shooters. If you shoot silhouette, definitely watch this video!
BULLET TRAJECTORY — Factors at Play and Zeroing Strategies
Host Jessie Harrison (formerly Jessie Duff) and Veteran Air Force Sniper and Long Range Expert George Reinas help us understand the factors behind bullet trajectory. NOTE: There are some exaggerations in the graphics in the videos, and inconsistent terminology use, but it’s still a helpful basic primer on the subject of trajectories. This popular video has over 1 million YouTube views.
INTERNAL Ballistics — Cartridge Ignition and Bullet in Barrel
What happens inside the barrel of your gun when you pull the trigger? In this edition of Firearm Science, Jessie Harrison goes over internal ballistics, which studies the combustion of propellant, the pressure developed, and the motion of the bullet along the bore of the barrel. There are some good 3D animations showing how the powder charge ignites and the bullet moves through the barrel.
CHOKE TUBES and Shot Patterns — Shotgun Science
With over 2.2 million YouTube views, this shotgun-centric video is the most popular of all the NRA Firearms Science series videos. Here Olympic trap shooter Corey Cogdell explains how choke tubes affect a shotgun’s shot pattern in this edition of Firearm Science. We recommend that all Shotgun hunters watch this video — it explains the effect of choke tubes very well.
ZEROING RIFLES for Long Range — Tech Tips
The process of zeroing rifles for long range is covered in this Firearm Science video featuring George Reinas, a veteran Air Force sniper. George demonstrates how to adjust his scope to compensate for bullet drop at long range. Our friend Dennis Santiago was involved in the making of this video, which was filmed at the Burbank Rifle & Revolver Club in Southern California.
EYE DOMINANCE — How to Determine Which Eye is Dominant
Host Jessie Duff and longtime shooter Krystie Messenger demonstrate how eye dominance affects aim and teach you how to determine your dominant eye in this edition of Firearm Science. There are very simple tests you can do to determine your eye dominance. This Editor is right-handed but left-eye dominant. All competitive shooters should check for eye dominance. If you are cross-dominant, you can alter your head position or put a paper patch on one frame of your shooting glasses.
NOTE: There are ten (10) shots in the group, but for simplicity we are only displaying five (5) shot circles. Adding more circles won’t change the measurement because the two most distant shots, which determine group size, ARE included.
What kind of 200-yard accuracy can you get in an enclosed, underground test range? Would you believe 0.162 MOA at 200 yards with a .338? Have a look at these test targets from Sierra Bullets. Like most bullet manufacturers, Sierra does live-fire bullet testing to ensure that Sierra projectiles perform as promised, with repeatable accuracy. Sierra tests bullets in its own underground test complex. Sierra’s 300-meter test range is the longest, privately-owned underground bullet test facility in the Western Hemisphere.*
Day in and day out, various bullet types are tested using a big collection of barreled actions. These barreled actions are clamped in stout, return-to-battery test fixtures. These big, heavy test fixtures provide near-perfect repeatability (with no human-induced holding or aiming errors).
Sierra Bullets 10-Shot Groups at 200 yards
Check out these 10-shot test groups shot at the Sierra Test Range at 200 yards. Note that the numbers listed on each sample are actual measurements in inches. To convert to MOA, cut those numbers in half (to be more precise, divide by 2.094, which is 1 MOA at 200 yards). For example, the 0.340″ middle group works out to 0.162 MOA at 200 yards.
Scan-Verified 0.162 MOA Accuracy at 200 Yards
To verify the accuracy of Sierra’s measurements, we measured the middle (.338 caliber) 10-shot group with our On-Target Group Measurement software. We registered a group size reading of 0.339″ — within one-thousandth of the Sierra measurement. The calculated group size in MOA (Minute of Angle) is 0.162.
That’s amazingly good for ten rounds of big .338 caliber bullets. A FIVE-shot 0.162 MOA group at 200 would be considered excellent at any benchrest match. But remember this target has TEN shots. The current, one-target IBS world record for ten shots at 200 yards is 0.245″, set by Ed Watson in 1999.
Bevy of Barreled Actions for Bullet Testing
Sierra Bullets uses dozens of barreled actions for testing bullets in its enclosed, 200-yard test range. Each barrel has its own logbook to track the barrel’s usage.

*Even Longer Test Tunnels Exist in Europe: At Stadeln in Germany, RWS (now part of RUAG) owns a 500 meter tunnel (above ground level) which has existed for decades. In Thun, Switzerland, RUAG has a fully-instrumented 500 meter underground tunnel. Near Ulm, Germany, there is a 5-lane 300 meter underground shooting range that is open to the public.
In 2019 CCI introduced a new type of .22 LR rimfire ammunition. CCI’s innovative Clean-22 Ammo features polymer-coated bullets. This is actually a pretty important development. The bullet coating on CCI’s Clean-22 ammo provides three main benefits:
1. Copper fouling in the barrel is greatly reduced.
2. Lead fouling in the barrel is greatly reduced.
3. Lead build-up in suppressors is reduced by 60-80%.
CCI has produced four versions of Clean-22 rimfire ammunition: Hyper Velocity (#954CC, 31gr, 1550 FPS MV), High Velocity (#944CC, 40gr, 1235 FPS MV), Subsonic (#934CC, 40gr, 1070 FPS MV), and Suppressor (#980CC, 45gr, 1000 FPS). These all feature lead bullets with polymer coatings. The Hyper Velocity ammo has purple-coated bullets, High Velocity ammo has red-coated bullets, Subsonic has blue-coated bullets, and the Suppressor version has black-coasted bullets. There was also a special 400rd Christmas pack of Clean-22 Hi-Vel ammo with Red and GREEN coated bullets, item #946XMAS.
Clean-22 Ammo with Polymer-Coated Bullets

Make Your Own Length-to-Lands Gauge to Check Bullet Position
Here’s a tip we feature every year or so, because it is something that costs nothing, yet can be very useful in the reloading process. With a simple, easy modification to a fired case, you can determine the length to lands in your rifle barrel. As long as you set the tension right, the measurements should be repeatable, and you’ve just saved yourself $43.93 — the combined cost of a Hornady C-1000 commercial OAL gauge ($37.99) and Modified Case ($5.94).
To achieve best accuracy with a rifle, you must control bullet seating depth very precisely, so all bullets end up in the same place relative to the entrance of the lands, every time. There may be multiple cartridge OALs which prove accurate. However, with each, you first need to determine a “zero” point — a reliable, and repeatable OAL where the bullet is “just touching” the lands.
There are tools, such as the Hornady (formerly Stoney Point) OAL Gauge, that will help you find a seating OAL just touching the lands. However, the tool requires that you use a special modified case for each cartridge you shoot. And, while we find that the Hornady OAL Gauge is repeatable, it does take some practice to get in right.
Make Your Own Length-to-Lands Gauge with a Dremel
Here’s an inexpensive alternative to the Hornady OAL tool — a slotted case. Forum member Andris Silins explais how to create a slotted case to measure length to the lands in your rifle:
“Here’s what I did to find length to lands for seating my bullets. I made four cuts into the neck of fire-formed brass. Then I pressed the bullet in lightly and chambered the entire gauge. As the cartridge chambers, the bullet slides back into the case to give you length to lands. It took less than five minutes to get it cut and working. A little light oil in the barrel just past the chamber helps ensure the bullet does not get stuck in the lands. It works great and is very accurate.
How to Adjust Tension — Length and Number of Neck Cuts
I made the cuts using a Dremel with a cut-off wheel. You can adjust tension two ways. First, you can make the cuts longer or shorter. Longer cuts = less tension. If you used only three cuts instead of four you would get more tension. The trick is to be gentle when you open and close the bolt. If you ram the bolt closed you may wedge the bullet into the lands. When you open the bolt it helps to keep a finger or two near by to guide the case out straight because the ejector wants to push it sideways.”
What are the negatives? Some of the stocks have a somewhat short length-of-pull, but this is easily solved with spacers. The main complaint is the factory trigger — some owners say it is too heavy at about 4 pounds, though the break is clean. For varmint work, we could live with the stock trigger and put money saved into optics.
In recent years, Browning has produced T-Bolt rifles in a variety of models, with many different stock types and various barrel lengths/contours. Most of the photos above showcase the AA Maple Sporter T-Bolt, which is currently out of production, though still available from some dealers (if you search). We like the looks of the AA Maple T-Bolt, but there many other stock options including dark brown, Black, Green, and various camouflage finishes.
