Barrel-maker Dan Lilja’s website has an excellent FAQ page that contains a wealth of useful information. On the Lilja FAQ Page as you’ll find informed answers to many commonly-asked questions. For example, Dan’s FAQ addresses the question of barrel life. Dan looks at factors that affect barrel longevity, and provides some predictions for barrel life, based on caliber, chambering, and intended use.
NOTE: This article was very well-received when it was first published last year. We are reprising it for the benefit of readers who missed it the first time.
Dan cautions that “Predicting barrel life is a complicated, highly variable subject — there is not a simple answer. Signs of accurate barrel life on the wane are increased copper fouling, lengthened throat depth, and decreased accuracy.” Dan also notes that barrels can wear prematurely from heat: “Any fast varmint-type cartridge can burn out a barrel in just a few hundred rounds if those rounds are shot one after another without letting the barrel cool between groups.”
Q. What Barrel Life, in number of rounds fired, can I expect from my new barrel?
A: That is a good question, asked often by our customers. But again there is not a simple answer. In my opinion there are two distinct types of barrel life. Accurate barrel life is probably the type most of us are referencing when we ask the question. But there is also absolute barrel life too. That is the point where a barrel will no longer stabilize a bullet and accuracy is wild. The benchrest shooter and to a lesser extent other target shooters are looking at accurate barrel life only when asking this question. To a benchrest shooter firing in matches where group size is the only measure of precision, accuracy is everything. But to a score shooter firing at a target, or bull, that is larger than the potential group size of the rifle, it is less important. And to the varmint hunter shooting prairie dog-size animals, the difference between a .25 MOA rifle or one that has dropped in accuracy to .5 MOA may not be noticeable in the field.
The big enemy to barrel life is heat. A barrel looses most of its accuracy due to erosion of the throat area of the barrel. Although wear on the crown from cleaning can cause problems too. The throat erosion is accelerated by heat. Any fast varmint-type cartridge can burn out a barrel in just a few hundred rounds if those rounds are shot one after another without letting the barrel cool between groups. A cartridge burning less powder will last longer or increasing the bore size for a given powder volume helps too. For example a .243 Winchester and a .308 Winchester both are based on the same case but the .308 will last longer because it has a larger bore.
And stainless steel barrels will last longer than chrome-moly barrels. This is due to the ability of stainless steel to resist heat erosion better than the chrome-moly steel.
Barrel Life Guidelines by Caliber and Cartridge Type
As a very rough rule of thumb I would say that with cartridges of .222 Remington size you could expect an accurate barrel life of 3000-4000 rounds. And varmint-type accuracy should be quite a bit longer than this.
For medium-size cartridges, such as the .308 Winchester, 7×57 and even the 25-06, 2000-3000 rounds of accurate life is reasonable.
Hot .224 caliber-type cartridges will not do as well, and 1000-2500 rounds is to be expected.
Bigger magnum hunting-type rounds will shoot from 1500-3000 accurate rounds. But the bigger 30-378 Weatherby types won’t do as well, being closer to the 1500-round figure.
These numbers are based on the use of stainless steel barrels. For chrome-moly barrels I would reduce these by roughly 20%.
The .17 and .50 calibers are rules unto themselves and I’m pressed to predict a figure.
The best life can be expected from the 22 long rifle (.22 LR) barrels with 5000-10,000 accurate rounds to be expected. We have in our shop one our drop-in Anschutz barrels that has 200,000 rounds through it and the shooter, a competitive small-bore shooter reported that it had just quit shooting.
Remember that predicting barrel life is a complicated, highly variable subject. You are the best judge of this with your particular barrel. Signs of accurate barrel life on the wane are increased copper fouling, lengthened throat depth, and decreased accuracy.
Benchrest Barrel Life — You May Be Surprised
I thought it might be interesting to point out a few exceptional Aggregates that I’ve fired with 6PPC benchrest rifles with barrels that had thousands of rounds through them. I know benchrest shooters that would never fire barrels with over 1500 shots fired in them in registered benchrest matches.
I fired my smallest 100-yard 5-shot Aggregate ever in 1992 at a registered benchrest match in Lewiston, Idaho. It was a .1558″ aggregate fired in the Heavy Varmint class. And that barrel had about 2100 rounds through it at the time.
Another good aggregate was fired at the 1997 NBRSA Nationals in Phoenix, Arizona during the 200-yard Light Varmint event. I placed second at this yardage with a 6PPC barrel that had over 2700 rounds through it at the time. I retired this barrel after that match because it had started to copper-foul quite a bit. But accuracy was still good.
Wind effects are complex. In trying to access wind speeds and angles, you’ll want to watch multiple indicators — mirage, dust, wind-flags, grass movement, and more. You’ll also need to be concerned about wind cycles. In the video below, Bryan Litz talks about variable wind speed along a bullet’s flight path. A respected ballistics guru, Bryan is the founder of Applied Ballistics and a designer of Berger’s Hybrid Match projectiles. He is also a past F-TR National Champion and a High Master Palma ace.
In this video, Bryan discusses how wind effects can vary in intensity at different points along the bullet’s flight path to the target. Sometimes the firing line is sheltered, and the strongest winds come into effect in the middle of the trajectory. Bryan concludes: “Wind matters everywhere … but the best thing you can do is try to get a handle on the wind [velocity and angle] where you are. That may or may not represent the wind down-range — that’s when you have to look downrange and make a judgment[.]”
Litz Competition Tip: Select your wind shooting strategy carefully. For beginners and veterans, most points are typically lost to wind. Successful shooters put a lot of thought into their approach to wind shooting. Sometimes it’s best to shoot fast and minimize the changes you’ll have to navigate. Other times it’s best to wait out a condition which may take several minutes. Develop a comfortable rest position so you have an easier time waiting when you should be waiting.
More Wind Tips from Wind Wizard Emil Praslick
In these two short videos, Emil Praslick III, former coach of the USAMU and USA National long range teams, explains how to find the wind direction and how to confirm your no-wind zero. Praslick is widely considered to be one of the best wind coaches in the USA.
When Winds Are EXTREME — Near Gale Force at Ben Avery
This video shows INSANE winds at NBRSA 100/200 Benchrest Nationals. This was filmed at the Ben Avery Range in Phoenix, AZ during the recent NBRSA 100/200 yard National Championships. Extreme to say the least. Based on what we’re seeing here, there are 20-25 mph crosswinds, with gusts to 35 mph — near Gale Force. Video by Hall-of-Fame Benchrest competitor Gene Bukys.
Texas gunsmith Mike Bryant reports: “This video shows the Unlimited Class 200 at the Nationals in Phoenix. I had three 10-shot groups in the low 2″ range with a 2.228″ being my big group and was glad they weren’t bigger. Thursday and Friday were the worst of the windy days. Unfortunately those were the days for the UL 200 and it was about as windy through most all of the Sporter 200.”
Excellent Wind Reading Resource
The Wind Book for Rifle Shooters covers techniques and tactics used by expert wind-readers. The authors provide a wind-reading “toolbox” for calculating wind speed, direction, deflection and drift. They explain how to read flags and mirage, record and interpret your observations, and time your shots to compensate for wind. Here are two reviews:
This is a must-have book if you are a long-range sport shooter. I compete in F-Class Open and when read it from cover to cover, it helped me understand wind reading and making accurate scope corrections. Buy this book, read it, put into practice what it tells you, you will not be disappointed. — P. Janzso
If you have one book for wind reading, this should be it. It covers how to get wind speed/direction from flags, mirage, and natural phenomenon. This is the best book for learning to read wind speed and direction. — Muddler
This would be an amazing group at 100 yards. But this 5-shot bughole was shot at TWO HUNDRED yards in competition by Bart Sauter of Bart’s Custom Bullets. And he did it with a borrowed barrel!
Be amazed. This five-shot group was shot at 200 yards in competition by bullet-maker Bart Sauter. Bart shot this astounding group with his 10.5-lb Light Varmint benchrest rifle at the recent East-West Match in St. Louis, Missouri. Had Bart been shooting an IBS match, this would have been a new IBS World Record, beating the .091″ by David Farrar in 2006. This .088″ group missed the NBRSA 200-yard 5-shot group record by a whisker — .013″ (thirteen thousandths). The listed NBRSA LV 200-yard Group record is 0.075″ shot by Johnnie Stewart a decade ago.
New record or not, this is one remarkably impressive group, shot by one very talented shooter and bullet-maker. Bart tells us he initially “held center” for the first three shots in the group. Then, watching his wind flags he noticed slight increase in the left-to-right condition, so he held 0.200″ to the left on shot 4 and it worked. Before shot 5, Bart detected another slight change, so he held 0.300″ left for the fifth and final shot. He explained: “If I had not held off for those last two shots, this group would have been about a flat four (0.400″).” Well done Bart!
“First three … bang bang bang … all went in one hole. Then I held left on shot 4 and it worked. On the last shot I held a little more, got lucky and it went in.” — Bart Sauter
In our Shooter’s Forum, Bart posted “This is my personal best-ever 5-shot group at 200 yards. I knew it was small, but was shocked to see it was a Zero! This will be a range record and record for the East/West match. Last group of the day! A nice way to end the match!”
Here is the 6PPC LV rifle that shot the .088″ group. Yes that’s a concrete shooting bench inside a pretty nice cabin with hunting trophies on the walls. Bart explained: “We reload and shoot out of the Monkey Hut, especially during the winter. Most of the time we shoot outside at 100/200 from a a three-bench range.
Amazing Group Shot with Borrowed Krieger Barrel!
There’s a very interesting side-note to this story. You see Bart doesn’t even own the Krieger barrel that delivered this amazing .088″ 200-yard group. That’s right this superb barrel was a “loaner” — borrowed from Bart’s buddy Gary Sullivan. [Editor: Oh that we could all be so lucky with borrowed components.] With Sullivan’s blessing, Bart has since loaned the barrel yet again to ace Billy Stevens, who will be using it at the World Benchrest Championship in Canada, July 14-21, 2019.
This photo shots Bart on the right and his good friend Billy Stevens on the left. Bart notes: “Billy is a 2-time Super Shoot Winner and 3-time USA World Benchrest Team member!”

Here is Bart’s target with a bullet removed. Bart was shooting his own 6mm 68gr Avenger bullets, a double-radius ogive design. The Avengers were seated about .004″ away from the lands: “I tried going into the lands and that didn’t seem to work, then I backed it off four thousandths [from contact] and the rifle liked that.” Bart drove those 68gr Avengers with a stout load of Accurate LT30 powder running 3407 FPS.
Bart’s Comments on His Components and Accessories
OPTICS — Bart likes his new 40x45mm IOR-Valdada Benchrest Scope. He says that, so far, it has proved very reliable and holds zero exceptionally well. This new design features a worm drive side-focus, oversized ocular with true +/- diopter adjustment, long eye relief, and fast-focusing reticle. The 40X Valdada also boasts superb HD “double-compressed” Schott glass from Germany.
TUNER — Bart says the Bukys TSI Tuner definitely helps. He notes that once he finds the “sweet spot” for his barrel he can normally leave it alone: “With that type of tuner, I have to be in a very dire straight to move it. Normally I will set it for the lifetime of the barrel.”
REAR BAG — Bart’s rear bag is an unusual Edgewood with softer gray leather. He says this was a special order by Bruno Shooters Supply. Bart likes how the rear bag works with his carbon-stocked 10.5-lb rifle: “With PPCs we ‘ride on the ears’ — this older bag just seems to work really well for that style.”
SUPER FEET — Bart told us he uses Benchsource Super Feet for his front rest: “The bench tops at St Louis are very slick. Before I set up I’ll use a spray bottle with water and wet the bench where the Super feet and rear bag will go. This really helps to keep things from sliding around!”

What components do world-class, short-range group benchrest shooters use? BAT actions, Krieger barrels, and Bix’n Andy triggers (and Jewells) are the components of choice. And barrel tuners are now widely used by the top shooters. As for powder, Vitavuori N133 is still the choice of virtually all top competitors. And yes the 6PPC definitely rules the roost. Every Top 20 shooter at the 2019 Super Shoot shot a 6PPC. Every one. Read on to learn more about the Top 20 Equipment used at this year’s Super Shoot.
We recently reviewed the Top 20 Equipment List for the 2019 Super Shoot at the Kelbly’s Range in Ohio. This Top 20 List reveals the gear choices for the 13.5-lb Heavy Varmint Class and the 10.5-lb Light Varmint/Sporter Class (20 entries for each division). Here are notable gear choices for Top 20 Competitors (both divisions) at the 2019 Super Shoot:
Actions: 14 of 20 HV and 16 of 20 LV/SP shooters used BAT actions. So there were 75% BATs for both classes combined. Barrels: 10 of 13 listed HV barrels and 9 of 12 listed LV/SP barrels were Kriegers. Overall, of the barrels identified in the Top 20 Equipment lists, 76% were Krieger. That’s dominance! [Note: We have been informed that entries with no barrel-maker listed may have been Bartlein barrels.] Triggers: Notably 10 of 20 HV triggers were Bix’n Andy — 50%. For the other class, 7 of 19 listed triggers were Bix ‘N Andy. All others were Jewells. Tuners: In HV Class, 12 of 20 shooters used tuners, mostly Bukys. 11 of 20 LV/SP shooters had tuners. Overall that is 57.5% tuner usage for both classes combined.
Cartridge: For both classes, every single Top 20 competitor shot the 6PPC. ‘Nuf said. Powders: 19 of 20 HV Shooters used Vihtavuori N133. Likewise 19 of 20 LV/SP shooters used VV N133, with one not reporting. That is total dominance for N133.
Bullets: There was a wide selection of bullets used in both classes. Custom bullets by “boutique” bullet makers were certainly favored by Top 20 shooters. Sta Moy 65s were popular, as were Hottenstein 68s and Bart’s bullets among others.
One of our Forum members, Jason Peterson, pulled off a remarkable accomplishment at an NBRSA 600-yard match last fall. Last October, at the Rogue Valley SSA range in Oregon, Jason set no less than FOUR new NBSRA Score Records: Light Gun 6-Target Score (30 shots), Heavy Gun 6-Target Score (60 shots), Two-Gun 6-Target Score (45 shots), and Two-Gun 12-Target Score (90 shots).
Jason was shooting a 6 BRA (6mmBR Ackley) Light Gun with Borden BRM action, LBR stock, and 1:8″-twist Krieger barrel. Bedding was done by Alex Wheeler. Notably, Jason’s father chambered the Krieger barrel — Thanks Dad! The load consisted of 108gr Bergers pushed by Hodgdon H4895. Writing in the NBRSA Magazine, Bill Johnston observed: “If my memory serve me right, this is the first time in Long Range History that 4 records were set at one match by the same shooter.”
AccurateShooter.com offers dozens of FREE, printable targets for target practice, load development, and fun shooting. We also offer a few of the most popular NRA Bullseye targets. One or more of these printable targets should work for most training purposes. However, some readers have asked: “Where can we get the real targets… exactly like the ones used in NRA, IBS, and NBRSA shooting matches?”
All these vendors carry nearly all the NRA High Power and Smallbore targets, including the new, smaller F-Class targets. Germany’s Kruger Targets sells all the important NRA targets, and international (ISSF) air rifle and smallbore targets too.
Orrville Printing currently sells IBS targets for rimfire (50 yard) benchrest, short-range centerfire Benchrest (100, 200, 300 yards), Hunter BR Rifle (100, 200, 300 yards), plus the official 600-yard and 1000-yard IBS targets.

.009″ — The Record That Stood for 40 Years.
In 1973 Mac McMillan shot an amazing 100-yard, .009″ five-shot group in a benchrest match. The .009″ group was measured with a 60x microscope for verification. Mac McMillan shot the group using a handbuilt prototype McMillan rifle with an early McMillan stock.
Mac’s .009″ group was the “Holy Grail” of rifle accuracy. This .009″ record was considered by many to be unbreakable, a record that would “stand for all time”. Well, it took 40 years, but someone finally broke Mac’s record with an even smaller group. In 2013, Mike Stinnett shot a .0077″ five-shot group using a 30 Stewart, a .30 caliber wildcat based on the 6.5 Grendel. Stinnett’s .0077″ group now stands as the smallest 100-yard group ever shot in registered benchrest competition.* Read About .0077″ group HERE.
Stinnett’s success doesn’t diminish the significance of Mac McMillan’s .009″ group in the history of benchrest competition. For four decades Mac’s group stood as the ultimate standard of rifle accuracy*. For those of you who have never seen Mac McMillan’s .009″ group, here it is, along with the NBRSA World Record certificate. The target now hangs in the McMillan Family Museum.
*Somebody else might claim a smaller group, but unless moving backers or electronic targets were used, it cannot be verified. Moving target backers are used at registered benchrest matches to ensure that five (5) shots are actually fired in each group. That eliminates any doubt.
We first ran this story in 2014, when Angelina was just ten years old. A Forum member recently asked if she was still shooting benchrest, and we can say the answer is yes — under the guidance of her grandfather Lou Murdica. So we are repeating the story today, to inspire all the other granddads who might encourage a little lady to take up the sport…
You have to love this story, supplied by our friend Lou Murdica. It seems that a petite little 10-year-old school girl finished fourth in a 100-Yard Benchrest match in Phoenix, beating some of the best in the business, including many Benchrest Hall of Famers. That’s right, shooting a remarkable 0.1612 Aggregate, little Angelina G. put a whupping on some very big names in the Benchrest game, including Lou Murdica himself. Angelina finished just .008 behind Hall of Famer Gary Ocock, beating other Benchrest superstars such as Bob Brackney, Lester Bruno, and Tom Libby. Angelina also beat legendary bullet-maker Walt Berger, but we’ll cut Walt some slack. Now in his 80s, Walt deserves praise for doing so well at the opposite end of the age spectrum.
Congratulations to Angelina on some great shooting in the Unlimited Class. Her five groups measured: 0.186, 0.172, 0.173, 0.121, 0.155. That’s impressive consistency. You go girl!
Point to ponder: If Angelina was shooting a Rail Gun, her rifle probably weighed more than she did.
Check out the big names who finished behind little Angelina.
Take a look at that group. That would be pretty nice for 200 yards. But this group was shot at 600 yards in competition by Fred Dobson at a recent NBRSA match in Oregon. The X-Ring is 1.2″ in diameter. Perfectly centered for a 50-5X, this Light Gun target should be a new NBRSA Score record, pending approval. The previous Score record was Ken Schroeder’s 50-4X.
Fred’s 600-yard group is also amazingly small. Using On-Target Software, we measured Fred’s five-shot group at 0.738″, which is a tiny 0.118 MOA at 600 yards.
NOTE: This is NOT an official measurement. The actual 5-shot group size might be larger or smaller, though it won’t be an NBRSA GROUP record. The current NBRSA 600-yard Light Gun group size record is 0.5823″ set by Robert Hoppe way back in 2008. But Fred’s 50-5X target should, indeed, be a new SCORE record.
Forum member “Jet” reports: “The Tri-County Gun Club just south of Portland, Oregon hosted its second NBRSA 600-guard match 11/18/2017. Twenty-one shooters brought rifles to the line. Fred Dobson shot the 50-5X target shown here.”
Congrats to Fred. Forum member KVD posted: “That’s truly fine shooting — something to be proud of. Seems like the bar gets boosted higher and higher every time there is a sanctioned match.”
