Sunday GunDay: 6BR Brothers in Arms — Pair of 6mmBR Rifles

6mm BR light & heavy gun

What’s better than a super-accurate 6BR rifle? Well, two super-accurate 6BRs. This week we feature a pair of tack-drivers owned Forum member Mark Schronce. These “Brothers in Arms” share similar stocks, but otherwise the components are different. Mark’s 17-lb gray laminate Light Gun features a Hall action, HV taper barrel, and muzzle brake. The 21-lb Heavy Gun, in “Desert Camo” laminate, boasts a trick dual-port BAT action, and full-contour 30″ barrel without brake. Both guns shoot tiny groups, track like they’re on rails, and give Mark a serious hardware advantage in club competition.

Mark provides this report: “The Light Gun started as my 22-250 AI varmint gun, with a Hall action and McMillan Hunter Benchrest stock. I wanted to build a proper Egg Shoot gun, so I had Richard Franklin (Richard’s Custom Rifles) chamber a Lilja 12-twist in 6mm BR Norma, with a .262″ neck. Using Fowler 80gr FB bullets, the gun shot great right out of the gate. (See my report, Egg Shoots and 600-yard 6 BR). I was curious about the heavier 6mm bullets, so I had Richard chamber and fit a 1:8″ Krieger in 6BR. But this time we went with a .271″ no-turn neck. The Krieger holds quarter-MOA with the heavy bullets, and, to my surprise, it shot the 80s as well as the 12-twist Lilja did. For the 2005 season, I ordered one of Richard’s latest 008 F-Class stocks. This new design is very comfortable to shoot and it’s much more stable in the bags than my old Hunter stock. That added stability will be a big plus for 600- and 1000-yard benchrest matches.

6mm BR light & heavy gun

A Heavy Gun for 1000-yard BR and “Belly Benchrest” (F-Class)
I’ve been active in 1000-yard Benchrest for a few years, shooting my 6mm BS and 6mm BR Light gun in both Light and Heavy classes. I wanted to build a rifle for the Heavy Gun Class yet stay within the 22-lb F-Class limit. And I wanted it to have the best hardware I could buy. On a BAT ‘MB’ action (with Jewell trigger) we fitted a 30″ 8-twist 3-groove Lilja, 1.250″ diameter, no muzzle brake. Richard cut the chamber for 6mm BR Lapua Brass, .271″ no-turn neck, throated for Sierra 107gr MKs, matching my current Light Gun. The stock is a pillar-bedded Richard’s 008 1000-yd/F-Class model, with 10 coats of auto clearcoat, all work by Richard. Burris Zee rings hold a Leupold 8.5-25×50 LRT mounted on a BAT one-piece Weaver base. The Heavy Gun weighs in at 21 lbs, much lighter than most Heavy Guns (50 to 100 lbs). But with the 6BR’s light recoil, it’ll do just fine for long range, yet still make weight for F-Class.

Why a 6mm BR Chambering in a Heavy Gun?
I toyed with the idea of going with a 6BR Improved for Heavy Gun, but I’m not convinced the Improveds are worth the extra hassle of fire-forming, not to mention the added cost of custom dies. By way of background, I used to have a Rem-actioned rifle chambered in 6BR BS (Bill Shehane), which is very similar to the 6BR Dasher. I found the 6BR BS was only about 100 fps faster than a standard 6BR. For the shooting I do, that extra 100 fps is not critical. If, in the future, I feel I need more speed, I will go to a .243 AI or a 6.5-284. To be honest, I love the 6BR cartridge. Barrels last forever, and the accuracy can’t be beat. Yes a 6BR is a little light for everyday 1000-yard shooting, but on good days it can set world records. I may move up to a 6.5-284 some day, but for now I will stay with the standard 6mm BR. If I ever do want to go to a bigger caliber, the 8.5-inch BAT Machine MB action gives me this option.

6mm BR light & heavy gunHall vs. BAT
Light vs. Heavy

Comparing the two actions’ bolt lift, lock-up, fit, and finish, I feel they are equally good. However, the BAT can run stout loads with Federal 205 primers — loads that cratered Fed 205s with the Hall. I don’t know if this is a function of the actions’ engineering, or the barrels. I’ve got a Lilja on the BAT, while the Hall wears a Krieger. I do know the BAT has a tight-fitting firing pin, and that might make a difference.

Both my actions have a built-in recoil lug — a really nice feature when you are changing barrels, and one of the main reasons I favor custom actions over a Remington. I think anyone would be pleased with either the BAT or the Hall.

There is a big difference in shooting a Light Gun vs. a Heavy Gun, as you might expect. The Heavy Gun is more stable and recoils straight back. However, even at 21 pounds, the Heavy Gun actually recoils harder into your shoulder than the muzzle brake-equipped Light Gun. But if you take the Light Gun’s brake off, and put the action back in the old Hunter bench stock, the gun would jump, torque and roll. It’s much better with the 008 stock now, but still not as rock solid as the Heavy Gun. On recoil the 21-pounder just tracks straight back, no jumping, no yaw, no rolling–very impressive.

6BR 6mmbr targetLoad Development and Accuracy Results
Developed last year, my favorite Light Gun load is 30.5 grains Varget, CCI BR4 primers, and 106gr Clinch River VLDs, running 2825 fps. The Light Gun shoots other bullets very well, but the Clinch Rivers performed best, with groups in the 0.1s to the low 0.2s at 100 yds. I use Lapua brass of course.

I began my load development for the Heavy Gun with components I had from last year: Varget, N140, and N540 powders, plus Fed 205, CCI BR4, and CCI 450 primers. I also had a good selection of bullets: 95gr and 105gr Bergers, 105gr Lapua Scenars, 106gr Clinch Rivers, and 107gr Sierra MKs.

The Heavy Gun liked the Bergers right from the start. During break-in and fire-forming (with 95gr Bergers 0.20” into the lands, 30.0gr Varget and CCI 450s), the rifle shot in the low 0.2s at 100 yds, 0.3s at 200 yds, with a 0.182″ small group at 200 yards (see photo). I then moved up to the heavier bullets and again the Bergers stole the show. Best load for the Berger 105s (seated 0.15″ into the lands) was 30.5 grains Varget and Fed 205s at 2850 fps. At 100 yards, this recipe shot in the 0.1s to the low 0.2s with a small group of 0.089″. (By the way, this same load in my Hall Light Gun would crater the Fed 205 primers. I may have to change to CCI BR4 primers for the hot summer days.) After working with the 105s I wanted to see how the Heavy Gun performed with lighter bullets. I tried my favorite Egg Shoot and 600-yard load–80gr Fowlers pushed by 31.5 grains of Vihtavuori N135 with Fed 205 primers. The results were fantastic. The big BAT produced a 100-yard aggregate (five, 5-shot groups) in the 0.2s with an 0.129″ small group. Overall, at 200 yards, both guns could agg five 5-shot groups in the 0.3s and 0.4s. Eggs Beware!


BAT actionBig, Strong, and Versatile
‘MB’ Action by BAT Machine

I looked at all the custom actions, and decided on a BAT model ‘MB’, configured Right Bolt, Left Port, Right Eject. The ‘MB’ action has some pretty unique features, including an integral recoil lug on the underside, and a recessed tenon (i.e. the threads start 1″ from the front of the receiver). The action is 8.5″ long, but with a 7.5″ bolt. The extra inch is added to the front. That provides extra bedding surface and room for a third pillar. The 8.5″ action length gives me the option to go up to a 6.5-284, while the dual ports should help give me the speed I need for the 10-round strings in Heavy Class. Also I can load from either side for F-Class.

Why did I choose a BAT? First, BAT quality is second to none. Moreover, BAT will custom-configure your port(s) and bolt for the same price, no added fees. Other action-makers charge extra for anything other than your basic Right Bolt, Right Port. This makes the BAT about the same price as a Stolle or Nesika, if you want a set-up like mine. The right-side ejection port is slightly smaller than the left feed port, but I can still feed 6BR cases from either side if I wish. The MB action is so big, the little BR case runs out of ejector as soon as the case leaves the chamber, so I push the case out to the right as I load the next round from the left. The BAT will eject a loaded 6BR round just fine, but a fired case only ejects sometimes. This action would work great with a longer round, such as a .243 AI or 6.5-284. If you want completely reliable 6BR ejection, you’ll need a smaller BAT action. But then, like my Hall standard action, the port would be too small for a 6.5-284.


Richard’s #008 Stock — How it Handles
The 008 stock is the best design I’ve ever shot off the bench. I like to hold my guns, and the 008’s grip profile gives me the control I like. The trigger is close enough for my short fingers. The underside of the buttstock is flat and completely straight (parallel to the barrel), so the gun tracks straight back. During recoil, the scope stays on target, making for quicker recovery time. In the picture at left, you can see that the underside of the fore-arm is relieved in the middle with raised strips on the left and right. These “rails” make for less surface area contacting the bags, less friction, and more consistent recoil. The high comb on the stock allows better prone shooting. For now, the stock is fine for what prone shooting I do. But if I do get seriously into into F-class I may want to add an adjustable comb or cheekpad. We’ll see.

Plans for Competition — The Lure of Hickory Groundhog Shoot Dollars
Some years ago, after building this pair of accurate 6mmBR rifles, Mark Schronce told us: “I can’t wait to see how this pair perform at long range. I will also take the Light Gun to the big Hickory GroundHog match in April, but I may put the barreled action back in the Hunter stock. This year you have to use bipods or sand bags, no front rest. [Editor: that is no longer the rule.] I don’t know if want to drill into my pretty new 008 stock for a bipod mount. I’ll let you know how it goes, and hopefully I’ll come back with some loot from the Shoot.” NOTE — that year Hickory offered about $8000 worth of prizes.

Sunday GunDay: .22 PPC for 300m Prone Competition

.22 PPC Rifle 300m prone

The 300 Meter .22 PPC — Smaller Caliber for Less Recoil

By GS Arizona
[This article originally appeared in Precision Shooting Magazine many years ago, but we are reprising it because the .22 PPC remains a notable cartridge for many disciplines, from benchrest to silhouette.]

I’ve spent the past few years pursuing the largely solitary pastime of 300 Meter shooting in the US. While it is a hugely popular sport in Europe, with thousands of competitors in each of various countries and overflowing national championships, in the U.S., 300 Meter shooting is simply a forgotten discipline. As an example, consider that the entry at the USA Shooting 300 Meter National Championships held at Fort Benning did not reach 20 competitors in [years past]. For those not familiar with the discipline, the 300 Meter ISSF target has a 100 mm ten ring, 200 mm 9 ring and so forth. That’s a 3.9″ ten ring at 328 yards for those of you who may object to the metric system, electricity and other intrusions upon a well settled universe (which ends at the dragons). [Editor’s Note: GS Arizona was a championship-class prone shooter, in both rimfire and centerfire disciplines, who had a popular online Blog, which has been closed.]

300 Meter Basics
300 Meter matches can be either three-position (prone, standing, kneeling) or all prone. Being of that age at which limbs aren’t limber and the mid-section obscures one’s view of the toes, I shoot prone matches only and leave the 3P to those for whom the term “shooting athlete” doesn’t produce an automatic smirk from the better half.

.22 PPC Rifle 300m prone

Like most 300 Meter shooters, I shoot a 6BR as my main rifle. As used in 300 Meter shooting, the 6BR is loaded with a 105-108gr bullet, with a velocity in the 2850 fps range. There is simply no cartridge out there at this time that delivers the accuracy, low recoil and ease of loading that can be had from the 6BR. That doesn’t mean we shouldn’t embark on a quixotic adventure now and then to find something better. This article is about one such search. So, if you don’t mind spending some time learning about an uphill struggle in a forgotten corner of the shooting world, pour a hot cup of coffee, get a plate of chocolate chip cookies and read on.

Getting Started–The Concept Behind the Project
The premise for building a .22 PPC was simple — less is more. Less recoil, that is, while retaining good ballistics and accuracy, should allow for higher scores. The hard part is meeting the ballistic and accuracy standards set by the 6BR. If pressed I might also admit to a desire to do something different. I made a decision early on in the project to stick to 80-grain bullets. I believe the 80 is pushing the envelope for safe and sane pressure in a case the size of the PPC; additionally, there are a number of manufacturers of 80-grain .224″ bullets so selection and testing can be more meaningful. Barrels are another consideration and all of the better barrel makers offer a 1:8″ twist .224 barrel (unlike the limited selection of 1:6.5″ twist required for 90 grain .224″ bullets).

With the basic parameters of a full-length .22 PPC case (reformed Lapua .220 Russian to be exact) and an 80-grain bullet established, a few other details needed attention. The first of these was specifying certain dimensions for the reamer maker. I chose not to change any of the essential dimensions of the .22 PPC such as headspace, shoulder angle or body taper, but there were a couple of areas that I felt needed to be different from the typical Benchrest PPC. These were neck diameter and throat length. With the outstanding quality of the Lapua brass, I elected to go with a 0.255″ neck diameter which would allow the use of unturned brass and still leave 0.002″ clearance around the neck of a loaded cartridge. The throat was specified longer than a standard PPC to allow for the length of the 80-grain bullets and avoid having the bullet go past the neck/shoulder junction.

Detours Along the Way
Like Quixote stumbling his way to his dreams, I’ve made a few mistakes. That 0.255″ neck diameter turned out to be the first. Turning brass isn’t a problem, but I was so captivated by the quality of the .220 Russian brass that I planned to skip turning or just take a light (0.001″) clean-up cut. Well, that’s fine, but as it turns out, PPC die makers assume you have turned necks and using unturned brass causes problems. The Redding Competition Seater, for instance, wanted to crimp the entire length of the neck onto the bullet. Turns out it was 0.250″ in the neck diameter of the sliding sleeve. This required reaming the sleeve which wasn’t too hard as the sleeve is made of relatively soft steel. Hand turning the chambering reamer with lots of care and oil took care of that problem. This opened up the neck to 0.255″ which might be 0.001″ more than ideal but I’ll live with it.

.22 PPC Rifle 300m proneSizing dies were another problem altogether. Forget using a non-bushing die with unturned brass–you’ll just overwork the neck to death. The Redding bushing dies worked well, though. Fired brass ends up at 0.254″ and is sized to 0.250″ in two steps (0.252″ and 0.250″) to maintain better concentricity.

I also got the throat length wrong as the base of the bullet (above the boat tail) is halfway up the neck and I want it just above the shoulder. I don’t know how I missed on that spec, but that’s what happened. As it turns out, the extra throat length hasn’t caused any problems with the Nosler 80, but it might with shorter or pointier bullets. Powder and primer choices became additional areas for demonstrating my inability to make good choices. You might think that adding a heavier bullet to an existing cartridge would be simple but it really turned into a full scale adventure.

Choice of Components and Smiths — Only the Best
Based on my previous favorable experience and that of a few friends, I ordered a Broughton barrel for the PPC, a .224″ bore 1:8″ twist, long enough to finish at 30 inches in what is generally referred to as a medium Palma taper. I haven’t been disappointed by the barrel: like all of those made by Tim North of Broughton Barrels, it is top notch. With the barrel and reamer in hand, they and the RPA Quadlite action were sent to Al Warner for barreling and then on to Alex Sitman for the stock. I can’t say enough good things about Alan’s metal work and Alex’s stock work. They have barreled and stocked many rifles for me over the years, all flawless. Alex’s Highpower Prone stock fits me like a comfortable moccasin. The trigger is a Jewell set at 4 oz., the rear sight is a Warner #1 and the front sight is a Scott Riles with a Centra aperture.

Eventually, the UPS man — purveyor of all things worth having — arrived with a long package and the real work began. Load testing and shooting can be a lot more frustrating than planning and talking to gunsmiths, but hopefully the eventual results make it worthwhile. I had a good supply of Nosler 80-grain bullets and some preconceived notions about powder and primers. Off to the loading bench.

Load Development + Accuracy Testing
Fire-forming the .220 Russian cases to the PPC chamber was a breeze: run an expander into the neck to get them to .224″, bump the shoulder 0.002″, load a caseful of IMR 4895 (about 23 grains) and insert a Nosler 77 (leftover from another project) and fire. I shot these at 100 yards while zeroing the rifle and was very impressed with the accuracy. Fouling was minimal, off to a promising start.

Once formed, I loaded the brass with Varget and the 80-grain bullets. Since Varget has given such good results in the 6BR, it was a natural starting point for this project. However, it quickly became evident that it might be too slow. While accuracy was excellent, powder fouling in the barrel was very heavy even at the highest charge tried (28.5 grains) and there was soot all the way down the shoulders of the cases. Cleaning the bore felt like patching a rusty water pipe after just 20 shots. I knew I’d never make it through a 60-shot match (about 70 shots with sighters) without cleaning[.]

Putting the .22 PPC to the Test in Competition
At this point, I took the PPC to a 300 Meter match with the Varget load. While it might not look perfect, I needed to try it. The first string was a 198 and I was able to clean the rifle immediately after firing. The second string was also a 198 but I had to fire the third string without cleaning. The effects of the fouling were evident in the last score, a 194.

While a 590 total isn’t bad for 300M, it was a bit below my average with the 6BR at this range – my home range that I knew well. More importantly, the score dropped as the group opened up in the third string when I wasn’t able to clean. At the Nationals all 60 shots are fired without a break for cleaning or additional sighters; therefore, Varget, while promising, wouldn’t work in the long run.

The next faster powder on my shelf was IMR 4895. I’d used it in the fire forming loads and if I had a lick of sense I would have tried it right away since the fire forming loads shot so well. However, stubbornly clinging to the preconceived notion that Varget was going to be a great powder for this combo cost me a month or so fooling with it. I then worked up loads with 4895 from 26.8 to 28.6 and saw that while 4895 was better suited to the case than Varget, it was still slow. The powder fouling was still occurring, though to a lesser degree. The shoulders still showed some soot, but less. I settled on 27.8 grains as a useful load and loaded 70 cases.

New Load for a New Home
At this point, I moved from Florida to Arizona causing a delay of several months in testing. The move also had an effect on the load as the hotter and drier climate in Arizona turned out to be much more suitable for 4895. Of course, I still had those 70 rounds loaded with 27.8 so I shot them in practice. Everything seemed OK but one primer (Federal 205M) pierced at the edge. I didn’t pay much attention to that as there were no other pressure signs and it was the first primer failure of any sort so far in this project. Extraction was fine, primer edges were nicely radiused and base growth was under two tenths. There was an opportunity to shoot a 500-yard prone match the following day so I reloaded the cases with the same load. At the match I pierced two more primers, this time right at the edge of the firing pin, causing two craters running into the firing pin hole. As you might imagine, all subsequent shots cratered into that area, although no more pierced.

I was contemplating a switch to Hodgdon Benchmark (slightly faster than H4895) until this point. Now, repairing the bolt face and switching to a tougher primer took priority. I loaded 25 rounds with CCI BR4 primers and 25 with Remington 7.5 primers. Both of these are well known for their tougher cups which I hoped would eliminate the piercing. I like the mild flash from the Federal 205 and believe it contributes to good accuracy, but I needed a primer that holds together more than I need to cut another tenth MOA. Bearing in mind that the powder charge itself might need reworking, I took those 50 rounds to the range to test them with the 27.8 gr. IMR 4895 load as it remains best to only change one thing at a time. Temperatures were in the 100 to 110 degree range during testing as they are for a good portion of the year here in Phoenix. If the load won’t work in hot temperatures, it just won’t work at all for me.

The primer testing at 200 yards showed the CCI BR4 primers to be better suited to this load than the Remington 7.5 primers. While no primer failed out of the 50 fired, the CCI BR4 primers gave distinctly better accuracy. I fired two ten-shot groups prone (scoped) with each, the Remington-primed groups averaged just over 1 MOA and the CCI-primed groups averaged 1/2 MOA. The difference between the two was principally in the amount of elevation in the groups. Given that result, as well as previous good experience with the CCI primers in the 6BR, I settled on the CCI BR4 primers for the PPC.

Final Testing at 500 Yards–It all Comes Together
While the purpose of the 80-grain PPC is 300 Meter shooting, those matches are somewhat hard to find so I’ve done most of my testing at 200 yards on the local public range (Ben Avery Shooting Facility in Phoenix) and at 500 yards in some of the local prone matches. With the primer issue potentially resolved, I went back to the 500-yard range to make sure the load held good elevation at that distance.

Final testing at 500 yards was a complete success. I fired one group of 24 shots from the prone position. Elevation for the bulk of the group was right at 3″ (0.6 MOA), the horizontal spread was somewhat larger as the group was fired in gusty, fast-switching conditions. The CCI BR4 primers functioned flawlessly, with no sign of pressure despite ambient temperatures over 100° F. None of this should be taken as a general statement of inadequacy of Federal primers. I have used (and continue to use) the very same lot of Federal 205M primers in my 6BR and have not experienced any problems at all. Simply stated, the 80-grain .22 PPC is an odd duck and has special requirements when fired under the conditions that prevail in my area.

At this point, I’ve determined that the basic premise of a .22 PPC for 300 Meter matches is perfectly viable, even if it is quite a bit more complex an undertaking than the 6BR. Recoil reduction over the 6BR was minimal, bordering on unnoticeable, but accuracy is on a par with the 6BR, perhaps slightly better. As a nice bonus, the PPC has proven to be quite useful for the 500-yard prone matches that are a regular part of the Phoenix shooting scene and it never fails to spark a good conversation with a new friend when I’m practicing or testing at the range. Future plans include testing Berger and Hornady 75 and 80-grain bullets and Hodgdon Benchmark powder. And, after conferring with your moderator, who ran some simulations in QuickLOAD, I’ll be trying Reloder 15 soon (QuickLOAD predicts RL15 allows 100% load density with good velocity). At some point I’ll also have the reamer reground for a shorter throat and tighter neck, but probably not until time comes to rebarrel.

6mmBR Norma versus .22 PPC

For the shooter who wants a superbly accurate, easy to load cartridge for 300 Meters to 600 yards, you simply can’t beat the 6BR. Everything you need, including brass, dies, reamers and knowledge are just a phone call away. The .22 PPC, by contrast, is an uphill struggle. The chambering reamer was custom ground to my specifications to allow unturned brass, as well as a longer freebore for the 75- and 80-grain bullets that are the heart of the project. The no-turn necks also meant that the Redding Competition Seater (an excellent unit) had to be reworked to allow for the thicker neck diameter. Once those hurdles were overcome I struggled to find the best powder for this combination–and I’m still searching. Unlike the 6BR where any of a half dozen or more powders will do the job (Varget, Reloder 15, N140, N540, IMR 4895, Norma 203B, etc.) the .22 PPC with heavy bullets has proven finicky with even the most accurate powders leaving fairly heavy carbon fouling.

Despite the problems, the .22 PPC offers a bit more pure accuracy than the 6BR and also a tiny bit less recoil. Both of these things can contribute to slightly higher scores in prone matches. However, to get the most out of the PPC, one must find the time to clean between 20 shot strings–a not inconsiderable effort sometimes in the mad rush of pit changes, scoring, shooting and just plain being tired.

This rifle was initially a .223 and when that cartridge proved unsatisfactory for my purposes, I had it rebuilt as the .22 PPC you see here. I like it and I enjoy the challenge, but I would not recommend this combination as someone’s primary rifle; it can get a bit frustrating. To put it into another context, the 6BR is like a 350 Chevy, it’ll just keep on doing the job forever, no matter what. The .22 PPC is like a Ferrari, it’ll scream when you do everything right, but it takes more attention to detail and a lot more maintenance. You wouldn’t want a Ferrari as your only car and likewise, you would be better off making the .22 PPC a second rifle.

Parting Shots — The .22 PPC vs. 6mm BR
If you’re looking for a simple, accurate and reliable cartridge for 200 to 600 yards, you probably can’t improve on the 6BR. However, if you’re someone who finds the journey as rewarding as reaching the destination, then you may very well enjoy a .22 PPC for prone shooting. While I received a great deal of help in this project from friends, gunsmiths, suppliers and parts makers far and wide, I really must acknowledge the huge debt we all owe to Ferris Pindell and Dr. Lou Palmisano. Without them there would be no PPC. We truly stand on the shoulders of giants.

Can’t Find Varget for Sale? Then Try IMR 4166 Powder…

IMR 4166 Enduron Varget powder Hodgdon

Can’t find Hodgdon Varget on dealer’s shelves? then consider IMR 4166. This Enduron series powder is temp-stable and accurate. It also offers good load density and meters reasonably well. Importantly, it seems to be a good substitute for “unobtanium” Varget powder. On the official Hodgdon/IMR burn rate chart, IMR 4166 is between H4895 and Varget. Some of our Forum members have reported excellent results with IMR 4166 in cartridges that work with Varget, such as the 6mmBR, 6 Dasher, 6.5×47 Lapua, and .308 Win. One member wrote: “in my 6.5×47 … IMR 4166 gives speeds and accuracy pretty much exactly the same as Varget.” And other shooters have observed reduced copper fouling with Enduron series powders, so IMR’s Enduron anti-fouling chemistry does seem to work.

IMR 4166 Enduron Varget powder Hodgdon

IMR Enduron powder 4166 Varget RL15Where to Find IMR 4166 Powder
Powder Valley Inc. (PVI) and Midsouth Shooters both have plenty of IMR 4166 in stock right now. IMR 4166 performs well in the .308 Win (for bullets up to 175 grains) and in 6mm cartridges running the heavier (95-107gr) projectiles. IMR’s press release states: “IMR 4166 [has] a perfect burn speed for cartridges like the 308 Win/7.62mm NATO, 22-250 Remington… and dozens more.”

IMR 4166 is one of IMR’s Enduron family of propellants. Enduron powders are formulated to reduce fouling and to be stable across a wide temperature range. If you commonly use Varget, Alliant Reloder 15, Norma 203B, IMR 8208 XBR, or Vihtavuori N140, you might want to try IMR 4166.
