Sunday GunDay: 6PPC Falling Block Ultra-Lightweight 97D

eben arthur brown model 97D falling block single shot 6 PPC rifle

While a 16.5-pound benchrest gun is wonderfully stable on the bench, it’s not what you want in a field rifle. There is much to be said for a slim, light-weight, and easy-handling firearm when it comes to a walking varmint adventure. Eben Brown, who runs E. Arthur Brown Company, has created just such a rifle — the Model 97D Falling Block. When chambered for the 6PPC cartridge it delivered quarter-MOA accuracy in a splendidly portable package that tips the scales at just over six pounds without scope. The Model 97D is fairly unique in its lightweight and compact format — that makes it a great field-carry varmint rig. [Editor’s Note: This is an older article and we use some more recent photos of other model 97D Rifles to better illustrate the design and layout.]

Excellent Accuracy Made Easy for Sport Shooters

by Eben Brown, E. Arthur Brown Company
You don’t have to be a benchrest competitor to enjoy shooting one of the most accurate centerfire cartridges in the world, the 6mm PPC. With no complicated brass forming or finicky reloading processes, you can be shooting near half-inch groups right from the start and hone your skills to near quarter-inch groups by your second outing–at least that’s how it worked for me, and I’m NOT a good bench rest shooter! Developed by Louis Palmisano and Ferris Pindell, the 6PPC has won more bench rest accuracy competitions than any other cartridge. Easily made from Lapua .220 Russian brass, the 6mm PPC has a small primer and uniquely small flash hole that is credited for much of its inherent accuracy. The “short, fat” shape and nearly straight body contribute to efficient, consistent powder burning and stable chamber performance (it grips the chamber well during ignition).

Eabco model 97D 6ppcThe Brown Model 97D — A Slim, Accurate 6-Pound Rifle
The 97D was developed from the EABCO “BF” falling block silhouette pistols that have won world championships and set 500-meter distance records. In operation, the 97D falling block slides perpendicularly and closes the breech with absolutely zero camming leverage. This makes it a perfect test-bed to measure the chamber performance needed for hand-loading most other single-shot rifles accurately. At the reloading bench, I worked up a load with the now fully shaped 6mm PPC brass. I full-length sized the brass, trimmed, and primed each case the same as I would with any other cartridge, and began loading. With the resultant load, I easily shot a 5-shot 1/4″ group, a personal best for me. See target photo at right.

Making 6mm PPC Cartridges
Full-length size, prime, charge with powder, and seat a bullet… sounds like what you do with any other cartridge, doesn’t it? In fact, the only difference with 6mm PPC is that it has to be fired once (fire-formed) to expand to its final shape and size. But even fire-forming shots produce exceptional accuracy. I shot several 3/4″ groups while fire-forming at 100 yards, with my best group at nearly half-inch–so the time spent fire-forming was wonderful! In the photo, the parent .220 Russian case is on the left, while the fire-formed 6PPC case is on the right.

The EABCO 6mm PPC Chamber
– 6PPC without Neck-turning!

We dimensioned our 6mm PPC chamber reamer to cut a chamber that fits Lapua 220 Russian brass closely without neck-turning. Naturally we recommend you use the Lapua brass for best results.

[Editor’s Note: We asked Eben if he had tried a 6BR chambering in a model 97D. He explained that, because of the extractor design, the falling block action works better with a smaller rim diameter: “The larger .308 rim width creates some issues. This design works best with cartridges no wider than the 30/30 case, or the 7.62×39 case, from which the 22 Russian case was derived. Cases with .308-sized rims develop more bolt thrust and work best with a different type of extractor than we use in the 97D. I love the 6BR, but I recommend the 6PPC for our 97D.”]

6mm PPC Reloading Data for Model 97D

The following loads were worked up in a Model 97D Rifle with 24″ barrel chambered for 6mm PPC with the chamber neck reamed to .275″ to fit Lapua brass without neck-turning. Lapua 220 Russian brass was full-length sized and fire-formed to 6mm PPC using 65gr V-Max bullets, CCI BR4 primers, and 24.5gr of VV N135 powder. Eben cautions: Load at Your Own Risk — Always start 10% low and work up

eben brown 97D Rifle 6ppcThe following optimum loads were worked up with Vihtavuori N135, 58gr and 65gr V-Max bullets, and CCI BR4 primers. Please Note: There really is no “standard” for 6mm PPC. It can be finicky. But once you find what works best for you, the cartridge performs superbly. The accuracy will astound you.

This video shows the Loading Technique for Model 97D Rifle

Powder Selection — Choosing the Right Propellant
I’ve found that my maximum single-shot loads reach the same level of performance as bolt gun loads when I use one level slower burning powder type and proper chamber preparation. For example, when the VihtaVuori loading guide shows a maximum with VV N133, my best single shot load ends up being with the slower burning VV N135. Here’s the simplest way to proceed: Use a starting load from the loading guide and increase the powder charge until you detect some resistance to block movement with your thumb. Next, charge a case with that same amount of powder, tap it to settle, and look to see if the case is full to the base of the neck. If it’s not full, step up to the next slower-rated powder and repeat the load development process. There’s a powder burn rate chart for all brands of powder in the front of the current VihtaVuori Loading Guide. When you have the maximum load that will fill the case and still allow the 97D single-shot to open and eject freely after firing, you’re ready to shoot some groups!

Loading for Best Chamber Performance
In the model 97D rifle you can check chamber performance easily. After firing a shot, see if you can press the block downward with only your thumb on the top of the block. If it moves freely, you’ve got good chamber performance.

I use three pressure indicators when developing loads on the Model 97D. First I check the block with my thumb. Then I check to see if the cartridge sticks at all when ejecting. And finally, I check the primer for the excessive flattening that would indicate too much pressure. Generally, the hottest load that still allows the gun to open and eject freely ends up being my most accurate shooting load.

Chamber Preparation
Best chamber performance happens when a cartridge grips the chamber and does not drive backward significantly. When you want something to grip (rather than slip), you want to make sure there is no lubricant on the gripping surfaces. Case forming lube and gun oil are the two lubricants you want to remove. Clean your 6mm PPC cases after sizing (I wipe mine with a paper towel and Windex). Clean your chamber with a chamber sized jag and patch wetted with acetone. (Note: protect your chamber with a thin coat of Clenzoil when you’re not out shooting.)

Conclusions of a Single-Shot Sport Shooter
I love the 6mm PPC! It was easy to hand-load for the cartridge and it was easy to get excellent results. The group shot on this page was with the 65gr bullet and a rifling twist of 1:10. I usually recommend a 1:12 twist and the 58gr bullet because customers have reported superb accuracy (better groups than I can shoot). But the 5-shot ¼” group I shot with this set-up is my personal best ever–so naturally I’m thrilled!

While it’s hard to beat the 6PPC’s accuracy in a Model 97D rifle, my company currently offers the rifle in a variety of chamberings including 17 Hornet, 219 Donaldson Wasp, and 6mm BRM. The 97D Standard features a blued 24″ chrome-moly barrel, French Gray receiver, anodized buttstock transition, 2-ring scope mount and swivel studs.– Eben Brown

About the production Model 97D Rifles: “The 97D is a small frame single shot rifle that’s suitable for big game as well as small game and varmint hunting. It originally evolved from our World Champion long range silhouette pistol action and incorporates the same accurate gun making processes. The 97D action itself is inherently accurate and simple. Onto this we fit an EABCO Accuracy Barrel, precision turned and threaded between centers. Each chamber is individually reamed on-center and individually head spaced. We feel the crown is so critical to accuracy that we leave it until after the gun is finished. Our 11 degree target crowns are cut last and left bright — our trademark finishing touch.”

Sunday Gunday: Bart’s 6PPC Drills Five Shots in .088″ at 200!

Bart Sauter Bart's Bullets 200-yard East Meet West
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!”

Bart Sauter Bart's Bullets .088 6PPC one-hole group 200 yards amazing

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.

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!”

SHOT Show Report: Murdica Tests New Norma 6PPC Brass

Lou MurdicaAt the request of AccurateShooter.com, respected Benchrest ace Lou Murdica tested the brand new, early production Norma 6PPC brass. Lou shot 30 cases (both turned and unturned) over the past few days, and he endorses the Norma brass without hesitation. Lou says “the Norma PPC brass is great brass. Without a doubt this will be highly competitive brass in the short-range benchrest group”. Lou did observe that the necks on the Norma brass were slightly thinner than on Lapua 220 Russian brass, but that really doesn’t matter. With a slight neck turn, Lou declares, “the Norma PPC brass is as good as any out there.”

Lou said, based on his testing, the Norma brass holds pressure well, and the accuracy is outstanding. Lou shot five 5-round groups, as in a match course of fire, and his largest group was “around 0.148″ at 100 yards.

If you’re a short-range benchrester, definitely watch this video and listen to Lou. He thinks this new Norma brass will “change the game”. Note — Lou said most PPC shooters can shoot the Norma cases with no change in their powder recipes. So you won’t lose any velocity using Norma’s new brass. Lou was very impressed with Norma’s new offering, enough so that he declared: “I would go right for the Norma right now if I could put a bunch in my hand.”

Norma Plans to Resume 6PPC Brass Production

Norma PPC brass This is potentially big news for short-range Benchresters and for varminters who shoot PPC variants. Norma has resumed production of 6PPC brass — at least on a prototype basis. NOTE: We don’t have many specifics. Norma has not firmly committed to exporting production 6PPC brass to the USA, nor has Norma announced a product release date. However, we received the following email today:

“After some work Norma has just started production of 6 PPC cases again. A new double-press has been installed which allows us to work-harden the case better. Internal tests are promising and we wonder if you would be interested to test a bunch.”

That’s it… we’ve shared all that we know for now.

Sunday GunDay: The Art of Firearms Engraving

engraved engraving rifle fuchs savage hornady

For today’s Sunday GunDay we present the merger of artistry and gunsmithing with a selection of elaborately-engraved rifles. These rigs are impressive to say the least. There are hunting rifles as you’d expect, but we even include a one-of-a-kind benchrest rifle with engraved action.

Amazing Double-Barreled Safari Bolt Guns

Here are some of beautifully-engraved safari rifles from Fuchs Fine Guns of Austria. These rifles feature a unique Double-barrel Bolt Action receiver, which is quite unique. Along with stunning wood stocks, the Fuchs rifles boast extensive detailed engraving with gold and jewelled highlights.

This DBR 48 Fuchs rifle with Celtic-themed engraving is chambered for the .470 Capstick caliber, the largest cartridge Fuchs offers. This rifle’s internal magazine offers a six-shot capacity. This DBR 48 was decorated in a Celtic motif. The bolt handle ends in a ball made of solid sterling silver. The magazine cover displays the Celtic boat symbol which stands for prosperity, wealth and power.

Benchrest Rifle with Engraved Stiller Action

A Very Unique Viper Action, Two Years in the Making
This is no ordinary Viper action. The full engraving attracts your attention, but there are some slick “performance mods” Jerry Stiller added at Speedy’s request.

Speedy thomas gonzalez 6mm PPC 6PPC 6 PPC christmas red rifle stiller viper engravedFirst, the action features a plain-Jane unfluted bolt, with a slight taper in the middle, a bit of a wasp-waist. Speedy prefers an unfluted design because it has superior wear characteristics. He’s found, when working with an aluminum action such as the Viper, the sharp flutes on the bolt will wear the inside of the action faster.

In the interest of reduced wear, Speedy also requested a smaller-sized loading/ejection port. This provides for a larger front and rear receiver ring, which enhances bolt bearing surface. More bearing surface reduces point loading for less internal wear.

First-Ever Hornady “Number One” Rifle with Baron Engraving

This “Hornady Number One” rifle was commissioned as the featured 2015 SHOT Show Gun. It was displayed in Las Vegas and auctioned on Gunbroker.com. The action and bottom metal is elaborately engraved by Baron Engraving of Trumbull, Connecticut. Hornady hired Bill Wiseman & Company to craft the barrel and action and Hornady commissioned Lucid Solutions (Clem Boyd) to build the stock. But the Hornady name IS now engraved on the side of a rifle receiver and that does represent a genuine first. This one-of-a-kind rifle, serial number “H-001″, is a bolt-action hunter, chambered for the .300 RCM cartridge.

Savage Rifle Created for Savage ArmsCompany President

When you run the company, you get some pretty nice stuff — in this case you get what may be the most elegant Savage ever made.

This rifle was created for Joseph V. Falcon, who served as President of Savage Arms in 1956. This highly embellished Savage 99 lever-action rifle is chambered for the .300 Savage cartridge. It features deluxe checkering and gold inlays. This presentation-grade rifle boast deep relief engraving with a golden elk on one side of the receiver and a stalking cougar on the other. This rifle was given to Joseph V. Falcon from his friends at Savage in December of 1967. Falcon later donated the rifle to the NRA. This impressive model 99 is currently showcased at the NRA National Firearms Museum in Fairfax, Virginia.

Savage 99 Quick History
Arthur Savage invented the first “hammerless” lever action rifle with the entire mechanism enclosed in a steel receiver. This rifle featured a rotary magazine with a unique counter that displayed the number of rounds remaining. The Model 99, as it became known, was the gun that launched a company. There is an interesting history of the company’s logo which features an Indian chief in feather head-dress. In 1919, Chief Lame Deer approached Arthur Savage to purchase lever-action rifles for his tribe’s reservation and the two men struck a deal. In return for discounted rifles and support, Savage received the tribe’s endorsement. By virtue of that association, Arthur Savage added the Indian head symbol to the company’s commercial trademark and letterhead.

Jesse Kaufmann — Modern Engraving Master

Jesse Kaufmann, who operates Black Hills Gunstocks and Engraving LLC in South Dakota, is a true master of metal engraving and he also does superb stock checkering. Here is an example of Jesse’s engraving work on a barreled action. Watch the video to see more of Jesse’s artistry.

Short-Range Benchrest Competition Captured on Video

Benchrest IBS 100 yards 6PPC Video

We know that many of our readers have never personally participated in a short-range (100/200 yard) benchrest match. That’s understandable — moving backers are required in registered 100/200 benchrest (for group) matches, yet only a small percentage of ranges have that equipment. If you’re curious about the “point-blank” benchrest game, but haven’t had the chance to see it first-hand, check out this video created by youtuber “Taofledermaus”. On his YouTube Channel, you’ll find many other interesting shooting videos, including slow-motion target impact clips. This video shows the LV and HV guns, the flags, the gun-handling, the reloading set-ups, and of course, tiny little groups on targets.

Registered 100/200 Benchrest Match

Viewer Comments on the Video:

“There is a lot more to this game than just pulling the trigger. Record targets are 5-shot groups, 5 averaged together for an Aggregate. Most times the winning Agg is under .250″ for 25 shots at 100 yards. Rifles weigh 10.5 pounds for LV class. Used rifles can be had for about $1500. Then add in another $1000 for rest, bags, loading tools, bullets, powder, not to mention windflags.” — Vmhtr

“Benchrest shooting is sort of an ‘academy of shooting’. Lots of academic thought and measurements, handloading made with anal attention at detail. It’s much more thought than action. Most of those people made their tools themselves. [There are] It’s plenty of seniors because it takes patience, lots of patience. Sure a teenager ain’t gonna bother it.” — THP

“I was surprised they did all their hand loading right there on the spot. — I think you nailed it. It’s a super-precise sport. It’s expensive, it’s slow, and it requires a lot of travel, so it’s well-suited for retired folks. It’s gotta beat golfing!” — Tao

“I used to shoot 6mm PPC in a BR rifle. I spent so much time at the reloading bench that I just gave up on it all and switched to 22 rimfire gallery matches. Saved a lot of my sanity doing that….” — Walt

What Determines Barrel Life — Dan Lilja Explains Key Factors

Lilja Rifle Barrels barrel life 3-groove AR15 Barrel heat

Barrel-maker Dan Lilja’s website, RifleBarrels.com has an excellent FAQ page that contains a wealth of useful information. On the Lilja FAQ Page you’ll find 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. 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.

Die Shims for FL Sizing Dies Give Precise Control of Bump

Sinclair Die Shims

When your cases become hard to extract, or you feel a stiff bolt lift when removing a cartridge, it’s probably time to full-length size your cases, and “bump” the shoulder back. We generally recommend bumping shoulders each time you reload, after the initial fire-forming. Benchrest and F-Class benchrest shooters, running relatively high pressures, typically full-length size every load cycle, bumping the shoulder .001-.003″. High Power shooters with gas guns generally full-length size every time, and may need to bump the shoulders .003″ or more to ensure reliable feeding and extraction.

Use Shims for Precise Control of Shoulder Bump
Some shooters like to set the “default” position for their full-length die to have an “ample” .003″ or .004″ shoulder bump. When they need less bump, a simple way to reduce the amount of shoulder movement is to use precision shims in .001″ (one-thousandth) increments.

Here are reports from Forum members who use the shims:

“Great product. I have my die lock ring(s) adjusted for the shortest headspace length on my multiple chambers 6BRs and 6PPCs. When needing a longer headspace, I just refer to my notes and add the appropriate shim under the lock ring. Keep it simple.” — F.D. Shuster

Mats Johansson writes: “I’ve been using [shims] since Skip Otto (of BR fame) came out with them. I set up my dies with the .006″ shim, giving me the option of bumping the shoulder a bit more when the brass gets old and hardens while still having room to adjust up for zero headspace, should I have missed the original setup by a thou or two. Hunting rounds can easily be bumped an extra .002-.003″ for positive, no-crush feeding. Being a safety-oriented cheapskate, I couldn’t live without them — they let me reload my cases a gazillion times without dangerous web-stretching. Shims are a must-have, as simple as that.” — Mats Johansson

Sinclair Die Shim Kit — Seven Shims for $14.99

Sinclair Die Shims

Sinclair Int’l (through Brownells) offers a seven-piece set of Sizing Die Shims that let you adjust the height of your die (and thereby the amount of bump and sizing) in precise .001″ increments. Sinclair explains: “Some handloaders will set their die up to achieve maximum sizing and then progressively use Sinclair Die Shims between the lock ring and the press head to move the die away from the shellholder. Doing this allows you to leave the lock ring in the same position. These shims are available in increments of .001″ and work very well.”

Seven Shims from .003″ to .010″
Sinclair’s $14.99 Die Shim Kit (item 22400) includes seven shims in thicknesses of .003, .004, .005, .006, .007, .008, and .010. For ease of use, shim thickness is indicated by the number of notches cut in the outer edge of each shim. Even without looking you can “count” the notches by feel.

How to Rebate Case Rims to Shoot Bigger Brass in PPC Actions

30BR 6 PPC rim rebated Butch Lambert

Many short-range Benchresters have thought about converting their 6 PPC to shoot a 30BR for score matches, or a Dasher for mid-range (or even 1000-yard) games. That way you have a rifle that does double duty, giving you the most bang for your buck. Though an action with a PPC bolt won’t normally work with 30BR/6BR/Dasher cases with their larger .308-class rim (0.4728″ diameter), there is a pretty easy solution that allows you to cycle these bigger cartridges with a 6PPC-style bolt (designed to fit .220 Russian rims).

“Rebating case rims … lets you shoot a 30BR in score matches using your PPC action. All you need is a new barrel. This saves buying another bolt, receiver, or rifle.” — Butch Lambert

Butch Lambert of ShadeTree Engineering provided this tip. Butch notes that many 6 PPC benchrest group shooters also enjoy shooting in score matches. But to be really competitive in the BR for score game, that means shooting a 30BR, which has a wider, .308-class rim (0.4728″ diameter). Likewise, if you want to compete in 600-yard registered BR events or in varmint matches, you probably want to run a bigger case, such as the 6BR, 6mm Dasher, or 6-6.5×47. Those cartridges also have the larger 0.4728″ rims.

Rebate Your 30 BR Rims
To convert a PPC-boltface action to shoot bigger cases you can spend a ton of money to buy a new bolt. That can cost hundreds of dollars. The simpler solution is to turn down the diameter of the larger cases on a lathe. Butch explains: “We’ve seen plenty of interest in rebating case rims. This lets you shoot a 30BR in score matches using your PPC action. All you need is a new barrel. This saves buying another bolt, receiver, or rifle if you have a PPC boltface. Anyone who has access to a lathe can do this job pretty easily. Yesterday I turned 150 case in about an hour.”

At right is the lathe form tool Butch uses to rebate the case rims.

Legendary Indoor Accuracy — Secrets of the Houston Warehouse

houston warehouse 6ppc secrets
Kelbly Light Varmint PPC Rifle from Gunbroker.com.

From the late ’70s through 1983, a huge, concrete-walled warehouse in Houston was used for benchrest testing. Virgil King and Bob Fisher set up a bullet-catching backstop at the end of a 30-yard-wide, 325-yard-long fire lane that remained unobstructed even when the warehouse was in use. This allowed accuracy tests in virtually perfect “no wind” conditions. Over a six-year period, about 30 shooters were invited to test their rifles. The results were amazing, with numerous “zero groups” being shot in the facility. Many of the lessons learned in the legendary Houston Warehouse still help benchresters achieve better accuracy today.

Dave Scott wrote a superb article, the Secrets of the Houston Warehouse which appeared in a special issue of Precision Shooting Magazine. That issue has long been sold out, but, thankfully, Secrets of the Houston Warehouse is now on the web: CLICK HERE to READ Secrets of the Houston Warehouse.

Houston WarehouseDave Scott explains why the Warehouse was so unique:

“Over a period of six years, the levels of accuracy achieved in the Houston Warehouse went beyond what many precision shooters thought possible for lightweight rifles shot from sandbags and aimed shot-to-shot by human eye. For the first time, a handful of gifted, serious experimenters — armed with the very best performing rifles (with notable exceptions) — could boldly venture into the final frontiers of rifle accuracy, a journey made possible by eliminating the baffling uncertainties of conditions arising from wind and mirage. Under these steel skies, a shooter could, without question, confirm the absolute limits of accuracy of his rifle, or isolate the source of a problem. In the flawlessly stable containment of the Houston Warehouse … a very few exceptional rifles would display the real stuff, drilling repeated groups measuring well below the unbelievably tiny .100″ barrier. The bulk of rifles, however, embarrassed their owners.”

Scott’s article also reveals some interesting technical points: “One thing that IS important is that the bullet be precisely seated against the lands. T.J. Jackson reported this fact in the May 1987 issue of Precision Shooting. In a letter to the Editor, T.J. wrote, ‘…in all our testing in that Houston warehouse… and the dozens and dozens of groups that Virgil King shot in there ‘in the zeroes’… he NEVER fired a single official screamer group when he was ‘jumping’ bullets. All his best groups were always seated into the lands, or at the very least… touching the lands. Virgil said his practice was to seat the bullets so the engraving was half as long as the width of the lands. He noticed an interesting phenomenon with rifles that could really shoot: if the bullets were seated a little short and the powder charge was a bit on the light side, the groups formed vertically. As he seated the bullets farther out and increased the powder charge, the groups finally became horizontal. If he went still farther, the groups formed big globs. He said the trick is to find the midway point between vertical and horizontal. That point should be a small hole.”

You should definitely read the complete article, as it provides many more fascinating insights, including shooting technique, barrel cleaning, neck-turning, and case prep.

EDITOR: Will the lessons of the Houston Warehouse work elsewhere? Is this repeatable magic? We remind readers that what T.J. Jackson discovered worked for his barrels, his cartridge type, and his choice of bullets. Jumping bullets can definitely produce good results in other cartridge types with bullets such as Berger Hybrids. Still, the Houston results are intriguing. Any time someone shoots in the “zeros” one should pay attention to how that was achieved.
