We’ve been giving a lot of coverage to tactical rigs and gas guns lately, so we though it was time to showcase a purebred, state-of-the-art 1000-Yard Benchrest rig. This article features the impressive .284 Shehane Light Gun used by Henry Pasquet to capture the 2013 IBS 1000-yard Nationals.
With a 5″-wide “hammerhead” front and a special 3″-wide bag-rider plate in the rear, this 17-lb rig is ultra-stable in the bags, and tracks like a dream. In this story, Henry explains his set-up plus his processes for loading super-accurate ammo. Every long-range shooter can benefit from some of tips revealed here. And F-Class guys — if you’re shooting a .284 Win-based case in F-Open you should definitely read Henry’s precision reloading advice.
EDITOR: Guys, there is a ton of solid gold information in this article — take your time and read it carefully.
Yes old dogs can learn new tricks. Just five years ago Forum member Henry Pasquet (aka “HenryP”) got started in 1000-yard benchrest shooting. He was 66 at the time. Henry worked hard, learned fast, and pursued accuracy with a vengence. That all paid off when Henry won the 2013 IBS 1000-yard Nationals this summer, finishing as the Two-Gun Overall National Champion. Henry was kind enough to talk about his rifle, his reloading methods, and his strategy for success. In fact, Henry was eager to share “everything he knows, so that other guys can fast-track their learning process”. Henry told us: “I want to share every lesson I’ve learned, so that other guys can improve their game and enjoy the sport more.” Henry also wants to encourage other senior shooters: “If you pay attention to details (when reloading), and get a good rifle with a good barrel, age is not a handicap. With a good set-up, older guys can compete with anyone out there. This is one sport where you can be a champion in later life.”

Q&A with Henry Pasquet, IBS 1000-Yard National Champion
Q: First, do you have any advice for older shooters getting started in their golden years?
Henry: You’re never too old. In this sport, you can excel even in your 60s, 70s and beyond. At this stage in life, we now have the time and money to get good equipment and rifles. Plus, our years of work experience help us to think, analyze, and thereby make progress. In this game, we older guys can definitely compete on a par with younger shooters.
HARDWARE
Q: Tell us about your Nationals-winning rifle and bench gear. Is there anything unique about your hardware that gave you an edge?
Henry: At the Nationals, I used my 17-lb Light Gun for both Light and Heavy Class. This rifle has a 1.55″, round BAT LP/RE action, fitted with a Bartlein barrel chambered for the .284 Shehane (an improved version of the .284 Winchester). The barrel was near-new; this was the first time I had used it this year. A great barrel and great batch of Berger 180gr VLDs all made a difference. Jay Cutright chambers my barrels. Jay’s metal-work is so precise that I can screw any barrel he’s chambered to any BAT action I own. The laminated stock was modified by Tommy Shurley from a standard 3″-wide fore-end to a 5″-wide True-Trac with an adjustable 3″-wide rear plate. It’s not pretty but it tracks like a Heavy Gun stock. Tommy made my other stocks as well.
On top is a Nightforce 12-42x52mm Benchrest scope with CH-3 reticle. I used a Fulghum (Randolph Machine) front rest with an Edgewood bag made with the low-friction 3M material. In the rear I use a special-order Protekor rear “Doctor” bag with ears spaced 3 inches apart. The rear bag also has the new 3M material on contact surfaces (photo at right).
Q: During the Nationals, at the last minute you switched guns. Why did you go from a 6mm Dasher to a 7mm Shehane?
Henry: I had planned to use my Light and Heavy Dashers, but after placing the Dasher on the ready line, decided to switch to the .284 Shehane. It was still early in the morning and I felt that the heavier bullets would be easier to see against the berm. The Dasher had actually been giving tighter groups under perfect conditions, but seeing the impact is important.
Q: Tell us about the combined tuner/muzzle brake on some of your barrels. How does this improve rifle performance and how do you set the “tune”? Do you tune the barrel to the load?
Henry: I use a tuner or tuner/brake on every barrel. I started with Time Precision tuners. Art Cocchia advised getting a load with a good known accuracy node with minimum extreme spread, which controls vertical. Do not go for the hottest loads, which just reduces brass life. Then use the tuner and tune the barrel to the load. The .284 Light Gun needed a muzzle brake and tuner. I had a local gunsmith cut a thread on the muzzle brake for a tuner I got from Sid Goodling. (Eric Bostrom developed an almost identical unit at the same time. I use Eric’s tuner/brakes on all my new barrels.) Just before Nationals, I tried going up and down one marker. Down one mark cut the group in half! Think how much range time (and barrel life) that saved me. Using a tuner is easier than messing around changing loads and tweaking seating depths. Tuners definitely can work. Last year I shot a 3.348″ 10-shot group at 1000 with my .284 Win Heavy Gun fitted with a Time Precision Tuner.
Q: What are the advantages of your stock’s 5″-wide fore-end and 3″-wide rear plate? Is there a big difference in tracking and/or stability? Does the extra width make the rifle easier to shoot?
Henry: I had true Heavy Guns with 5-inch fronts and 3-inch rears. They tracked well. I felt the same result could be had with a Light Gun. I talked two stock makers into making them. I initially had the standard rear stock until Tommy Shurley and Mike Hearn came out with an adjustable rear plate. The stocks track perfectly. You can see your scope’s crosshairs stay on the target the whole time and push the rifle back for the next shot. There is no torquing (gun wobbling) when cycling the bolt. Us old guys need all the help we can get. I am getting rid of my 45-pound Heavy Guns and replacing them with Light Guns with heavy barrels.
Q: Some people say the .284 Shehane is not as accurate as the straight .284 Winchester. You’ve proved them wrong. Why do you like the .284 Shehane? More speed, less pressure?
Henry: The reason I rechambered my 7mm barrels to .284 Shehane was not velocity, pressure, or brass life. It was all about bolt lift. My straight .284 almost required me to stand up to eject brass. I damaged an extractor and had to send the bolt back to BAT. With the .284 Shehane, my bolt cycles like there is no case to eject.
Reloading Methods
Q: People want to know about your load and your loading methods. What can you reveal?
Henry: For my .284 Shehane at the Nationals, I loaded 52.5 grains of Hodgdon H4350 and Federal BR-2 primers behind Berger 180gr VLDs. I usually anneal the brass each winter. I have used the same brass for years. I use Redding bushing dies, apply Imperial sizing wax, resize, wipe off wax, clean and uniform the primers pockets using the RCBS Trim Mate Case prep center, then apply Imperial dry neck lube with a bore mop.
To dispense powder, I use a RCBS ChargeMaster set 0.1 grain below my desired load and then weigh them on a Sartorius GD-503 magnetic force restoration scale to get identical charges. I use a K&M Arbor Press with seating force gauge when seating the bullets with a Wilson inline die. My “target” seating force on the K&M dial is 20-23 units for Dashers and 35-40 units for the .284 Shehane. I put any variables aside for sighters. I do not weigh brass, bullets, or primers. My bullets were so consistent that I did not sort by bearing surface. I did trim the Berger VLDs to the shortest bullet length with a Hoover Trimmer, and then pointed the meplats just enough to close them with a Whidden pointer. I sort my bullets to 0.005″ overall length, rejecting about five percent.
Q: What kind of precision are you looking for in your reloads? Do you trickle to the kernel? Does this really help reduce extreme spread?
Henry: I try to keep my charge weights consistent to one kernel of powder. I use the Omega powder trickler with a Sartorius GD-503 lab-grade balance to achieve that. For accurate dispensing, put very little powder into the Omega so you can drop one kernel at a time. Single digit ES (Extreme Spread) is the goal. This does make a difference at 1000 yards. If you get the same push on the same bullet with the same neck tension, good things are going to happen.
Q: You believe consistent neck tension (i.e. grip on the bullet) is really important. What methods are you using to ensure consistent bullet release?
Henry: I apply Imperial dry neck lube to the inside of my case-necks with a bore mop. The K&M arbor with seating force gauge shows the need to do this. If you put a bullet into a clean case, it will be jerky when seating the bullet. You may see 40 units (on the K&M dial) dropping to 20, then slowly increasing pressure. I explained to a friend that not lubing the neck is like overhauling an engine without lubing the cylinders. Smooth entry gives the bullets a smooth release.
Barrel Cleaning
Q: You go 60-80 rounds between cleaning and the results speak for themselves. What is your barrel cleaning procedure? Do you think some guys clean too often or too aggressively?
Henry: I cringe when I see people wearing out their barrels with bronze brushes between relays. I clean my barrels at the end of each day when I get home. I shot my best-ever 1K Heavy Gun group (3.348″) at day’s end after 60 to 80 rounds. After trying other solvents, I have gone back to Wipe-out’s Carb-Out and Patch-Out products. I use about four patches of Carb-Out, let it sit a few minutes, then use one stroke of a nylon brush followed by Patch-Out until the barrel is clean. I use a bore mop to clean inside the chamber, then some Break Free LP on the bolt followed by bolt grease on the lugs and cocking part. I use a bore guide when anything goes down the barrel.
Shooting Skills and the Learning Process
Q: Henry, you can shoot long-distance on your own property in Missouri. How important is practice, and what do you do during a typical practice session?
Henry: I can shoot 1000 yards on my farm. I have a concrete bench using a slab from a yard furniture place on concrete blocks. Two 4 x 8 sheets of plywood hold four IBS targets. I never practice. I only test, keeping a notebook with all the info. I do most of my testing at 300 to 500 yards, shooting off my deck so I can see my shots immediately.
Q: How much of your success do you credit to really accurate rifles, versus superior shooting skills?
Henry: I do not consider myself another Carlos Hathcock or some master marksman. I am an average 1000-yard shooter, but I do work hard getting the most out of my rifles. Four other people have shot their first 1000-yard matches with my rifles, including my wife, and all of them won relays! I loaned my Dasher to another shooter two years ago and he got second at the 600-yard Nationals. Others will tell you that the rifle must be “on” to win. If your barrel or bullets are average, don’t expect to perform above average in competition.
Q: What you do enjoy most about long-range benchrest shooting? What are the attractions of this sport?
Henry: The sport offers good people and a real challenge. 1000-yard shooting keeps us all humble, but we still keep trying to see how good we can do. I am thankful for Robert Ross providing the only match location that I can shoot regularly.
Q: Henry, you have been a Forum member for many years. Have you learned important techniques from other Forum members and other shooters?
Henry: I have followed the AccurateShooter Forum since 2008. At my age I am not good at computers. I copied and analyzed many articles, especially on the .284 and the Dashers. Without AccurateShooter.com, I would probably still be shooting double-digit (10″+) groups at 1000 yards, and I sure wouldn’t have my name on a National Championship trophy.
Q: You are in your 70s now and have only been shooting competitively for a few years. How did you get so good so fast? How did you manage to beat shooters who are decades younger?
Henry: I had 20/10 vision when I was young, but am down to only 20/20. I have been interested in long range shooting for a long time including ground hog hunting. I went to some VHA jamborees also. In 2008, I went to the Williamsport Benchrest School with a friend from Pennsylvania, John Haas. We would compare notes frequently. I bought a BAT three lug from Tom Mousel in Montana. We also compared notes and made each other better. At IBS matches I studied other shooters’ equipment and techniques. I tried some, accepting some and rejecting some.
Here’s my advice:
Always be ready to learn something new. If it makes sense, try it. I would also encourage other older shooters not to quit. Stick to it. You can make enormous progress in a few seasons.
TEN Shots in 0.303″ (0.289 MOA) at 100 Yards
How does Dan’s XP-100 pistol shoot? Look at that target showing TEN shots at 100 yards, with eight (8) shots in the main cluster at the top. The ten-shot group measures .303″ (0.289 MOA), as calculated with OnTarget Software. Not bad for a handgun! What do you think, can your best-shooting rifle match the 10-shot accuracy of this XP-100 pistol?
Report by Boyd Allen
This pistol belongs to Dan Lutke, a Bay Area benchrest shooter who publishes the results for the Visalia matches to the competitors and the NBRSA. He has been an enthusiastic competitor for an number of years, at various ranges, notably Visalia and Sacramento. The action is a Remington XP-100, to which a Kelbly 2 oz. trigger has been fitted. On top is an old Japanese-made Tasco 36X scope (these were actually pretty darn good). The Hart barrel (a cast-off from Dan’s Unlimited rail gun) was shortened and re-chambered for the 6x45mm, a wildcat made by necking-up the .223 Remington parent case. The custom stock/chassis was CNC-machined by Joe Updike from 6061 Billet Aluminum to fit the XP-100 action and mount a target-style AR grip with bottom hand rest. The gun was bedded and assembled by Mel Iwatsubu. In his XP-100 pistol, Dan shoots 65gr custom boat-tails with Benchmark powder.
This diagram shows the most common 6x45mm wildcat, which is a necked-up version of the .223 Remington parent cartridge. NOTE: The dimensions for Dan Lutke’s benchrest version of this cartridge may be slightly different.

Registration Opens for 2017 CMP Springfield M1A Match
The 11th annual Springfield Armory M1A Match will take place during the 2017 National Trophy Rifle Matches. The CMP will host the event on Saturday, July 22, following the John C. Garand Match. Competitors of all experience levels are encouraged to bring their M1A rifles to Camp Perry and compete. Registration for the match will open April 1, 2017, and is open to all individuals ages 12 and above, with an entry fee of $50 (junior $25).
The Springfield Armory M1A match began with one man’s idea and passion. Springfield Armory’s Mike Doy witnessed the waning of classic M1 Garand and M1A rifles from the competitive High Power firing lines. “I really wanted to get those M1A rifles out of safes and closets and back out onto the field. So 11 years ago, I promoted the idea of running an M1A-specific match at Camp Perry. That first year we had over 600 competitors and spectators.” Now the match offers some of the biggest pay-outs at Camp Perry. In recent years, Springfield Armory has donated over $25,000 worth of cash and prizes, including a $2,000 cash award to the overall winner.
This illustration shows headspace measurement for the popular .308 Winchester cartridge, which headspaces on the shoulder. Image copyright 2015 Ultimate Reloader.
In this Brownells Tech Tip, Brownells gun tech Steve Ostrem explains what headspace is and why it’s one of the most critical measurements for nearly all firearms. Even if you’re an experienced rifle shooter, it’s worth watching this video to refresh your understanding of headspace measurements, and the correct use of “GO” and “NO-GO” gauges.
Headspace Definition
In firearms, headspace is the distance measured from the part of the chamber that stops forward motion of the cartridge (the datum reference) to the face of the bolt. Used as a verb, headspace refers to the interference created between this part of the chamber and the feature of the cartridge that achieves the correct positioning. Different cartridges have their datum lines in different positions in relation to the cartridge. For example, 5.56x45mm NATO ammunition headspaces off the shoulder of the cartridge, whereas .303 British headspaces off the forward rim of the cartridge.
If the headspace is too short, ammunition that is in specification may not chamber correctly. If headspace is too large, the ammunition may not fit as intended or designed and the cartridge case may rupture, possibly damaging the firearm and injuring the shooter. (Source: Wikipedia)
Headspace Gauges
Headspace is measured with a set of two headspace gauges: a “Go” gauge, and a “No-Go” gauge. Headspace gauges resemble the cartridges for the chambers they are designed to headspace, and are typically made of heat-treated tool steel. Both a “Go” and a “No-Go” gauge are required for a gunsmith to headspace a firearm properly. A third gauge, the “Field” gauge, is used (as the name implies) in the field to indicate the absolute maximum safe headspace. This gauge is used because, over time, the bolt and receiver will wear, the bolt and lugs compress, and the receiver may stretch, all causing the headspace to gradually increase from the “factory specs” measured by the “Go” and “No-Go” gauges. A bolt that closes on “No-Go” but not on “Field” is close to being unsafe to fire, and may malfunction on cartridges that are slightly out of spec. (Source: Wikipedia)
To learn more, read Brownell’s longer article Headspace Gauges and How to Use Them. Among other things, this explains the relative lengths of “Go”, “No-Go”, and “Field” gauges. The “Field” is actually the longest: “The GO gauge corresponds to the SAAMI (Sporting Arms & Ammunition Manufacturer’s Institute) minimum chamber length, while the FIELD gauge usually matches the maximum chamber depth, or slightly less. NO-GO gauges are an intermediate length between minimum and maximum, that, technically, is a voluntary dimension. A firearm that closes on a NO-GO gauge and does not close on a FIELD gauge may not give good accuracy and may have very short cartridge case life from the ammunition re-loader’s standpoint.”
A little work with the hand axe, after a trip through the band saw…
A while back, Forum member Preacher crafted a nice varmint rifle for fellow Forum member Dave 0. (aka “Waskawood”). But rather than buy an off-the-shelf stock, Preacher crafted this stock all by hand, starting from a laminated blank panel. He calls this stock project his “Axe Job”.
CLICK for Full-size Photo
This stock is being used on a prairie dog rifle, chambered for a 17-caliber wildcat, the 17 VHA, which is based on an H&K 4.6x30mm parent case. With about nine grains of 300 MP pistol powder, the 17 VHA drives 20-grainers at about 3850 fps. (SEE details at end of article).
The ‘Axe Job’
Report by Preacher
I like carving with the laminates because all the lines are right there in front of my eyes, so it’s easy to follow along and get it just right, until it’s pleasing to the eye. I never use a template, I just keep checking the lines as I go along. I have all the needed equipment to power build one of these, but I really enjoy the time spent on the hand work. From start to completely ready-to-install, I’ll have about six (6) weeks into one of these stock projects. A lot of that is drying time for the clear coats.
The majority of the laminated blank panels I use for my gunstocks are purchased directly from Cousineau Wood Products or from Rutply.com. You have to buy at least four full panels at a time, all the same color, but that will yield eight (8) stocks. Seems like I have a little over $150.00 in a blank large enough to start making a full-sized, benchrest-style stock.

Preacher’s Advice on Carving Your Own Stock
The one main advantage of being older that dirt, and tormented with MS the past 40 years, is lots of free time to enjoy what ever I can do these days, as long as I can set down to do it, and I can make a lot of wood chips setting down.
Any one can do this if they have the time to devote to it. All it takes is time and a good eye for details. I made a lot of firewood over the years, until I got the hang of it. Most all those problems were inletting, and screw hole spacing. Get those right the first time and you’re on your way….
A little more work with the rasp…

Micro 17 VHA Wildcat Here’s the finished rifle built by Preacher for Dave, using the ‘Axe Job’ stock. Dave tells us: “Preacher chambered the rifle for the 17 VHA, a wildcat based on the H&K 4.6x30mm MP7 PDW case necked down to 17 caliber. There are numerous articles in the Varmint Hunter’s Magazine about it. This efficient little round shoots 20gr ballistic tips at 3850+ fps. That’s not too shabby for ‘nine point something’ grains of pistol powder.”
“My intentions for my 17 VHA rifle are to plop down in the middle of a PD town with my swivel bench and shoot prairie dogs. I also thought it would be a nice platform to test the accuracy of the cartridge. If I like the little round as well as I think, I plan to build a more practical rifle that I can carry. I really want to thank Preacher for his patience with me through this project, as it was my first custom build.”

TT Freestyle’s Husband and Wife Borden Benchrest Rifles
Here’s a pair of “His and Hers” rigs delivered by Santa in December. Forum member TT Freestyle reports: “After our rookie year in Short Range Benchrest with good used equipment, my wife and I decided we liked it enough to get two new Bordens for Christmas!”
FalconPilot’s Fabulous F-Classer in Shurley Claro Walnut Stock
This beauty belongs to Forum member FalconPilot. He tells us that his “Lastest F-Classer features a Shurley Brothers SOD stock in beautiful Claro Walnut.” Components include Bat M action, Bix-N-Andy trigger, and Nightforce Comp scope. FalconPilot has several barrels for this Open-Class rig, including tubes chambered for .284 Win and 6mm Dasher.
Eric’s Blacktical .308 Win for Precision Rifle Series
Forum member Eric32 spent months building out this rifle, “getting it to work just right for PRS”. Designed for practical/tactical matches, this rugged rig features a blue-printed Rem 700 action (with 1.5-lb 40X trigger) in an XLR Element chassis. On the end of the .308 Bartlein 5R barrel is a JP brake. Other components include: PiG skins barricade grips, Atlas Bipod, and GGG bungee sling. On top is a SWFA HD 5-20x50mm optic with Vortex scope level and custom throw-lever.
Forum member Willow reports: “Here is my new F-Open gun. It features a hydro-dipped LowBoy stock and LH Barnard Model P action with ‘V’ bedding block. The barrel is a straight profile 32″, 1:8.5″ twist Bartlein 5R, chambered in 280AI by Matt Paroz”. On top is a Vortex 10-60x52mm Golden Eagle in a Spuhr 3001 mount. Willow says his lightning bolt rig is a shooter: “After 42 rounds through the barrel, I’m liking what I am seeing so far”. Check out that trick aluminum base for his rear Edgewood bag.
Stinnett’s 6.4×47 Lapua Tactical Rig
Forum member Stinnett tells us: “This is my third 6.5×47 Lapua rifle — the 6.5×47 is the best cartridge ever! I’m not a huge fan of muzzle brakes. I look at them as tools — use the correct tool for the job. The ’47 doesn’t need a brake. .308 Winchester and up need muzzle brakes. For this rifle, I’m going to start out with 123gr Scenars and Reloder 15. I also like to shoot the 123gr SMKs and Varget. The SMKs are much less seating-depth sensitive. Very easy to find a load! Also gonna try the Berger 130 Hybrids and H4350.”
Components: McMillan A5 adjustable stock in GAP Camo, Stiller TAC 30 A/W action, Jewell HVR trigger, Badger bottom metal and DBM, Atlas Bipod, Nightforce NXS F1 3.5-15×50 with MLR 2.0 reticle. Metal has been Cerakoted graphite black.
6mm BRX Benchgun with Home-Made Cherry/Redheart Stock
You have to give credit to a guy who crafts his own custom wood stock. This 6mm BRX benchgun features a custom-built laminated stock featuring Cherry wood with vivid Redheart pieces on the sides and Redwood Burl on the buttplate. The front of the stock is 4″ wide. The action is a Benchrest Borden RBLP Right Eject unit, with custom titanium scope rings on top. Owner Erick C. is proud of this stock, saying it is “the best one I’ve built so far”. We agree it’s a beauty.
Ever wondered how the parts inside an AR15 work together? Just exactly how does the reciprocating bolt carrier feed rounds from the magazine? How do the elements in the trigger group work and reset after each shot? How does the gas system bleed gas from the barrel and operate the bolt carrier? These and other questions are answered in this eye-opening video from 45Snipers. Using “cutaway” 3D computer animation, this 5-minute video shows all features of an AR15 inside and out. This fascinating firearms animation allows the viewer to look inside the upper and lower receivers, into the bolt carrier, chamber, barrel, and magazine.
This video starts off slow and has annoying background music, but it is well worth watching if you own or shoot any AR-platform rifle. It illustrates all the key operations during the charging, loading, firing, and ejection processes. The cutaway animation shows how rounds are stripped from the magazine and then chambered. It then shows how every part of the trigger group works, and how the firing pin strikes the primer. You can even watch the bullet move down the barrel before the empty shell casing is removed from the chamber and tossed out the ejection port. Here are sample frames from the video:

With all the blacktical rifles and tacticool camo gear on display at SHOT Show, it was nice to see some old style craftsmanship — hand-built rifles with colored case-hardened receivers, fine engraving, and beautiful wood. We found just that at the Shiloh Sharps booth. The heritage style of the Shiloh Sharps rifles harkens back to another era, when the West was still wild, and gifted smiths crafted rifles with pride, skill, and true artistry.
The cartridges shown in the photo (left to right above rifle) are: 45-110, 50-100, 45-90, and 40-70.
This video shows how Shiloh Sharps crafts its rifles, from “Foundry to Finish”:

Each Wednesday, the U.S. Army Marksmanship Unit publishes a reloading “how-to” article on the USAMU Facebook page. Last week’s “Handloading Hump Day” article covered mechanical issues and related ignition irregularities that can cause vertical fliers even with good ammunition in an otherwise excellent rifle. We highly recommend you read this article, which offers some important tech tips.
Vertical Dispersion: Mechanical/Ignition Issues?
Poor or inconsistent ignition has long been known to be one of the “usual suspects” when one encounters vertical fliers that just shouldn’t be there. By having a sense of some of the basic principles involved, and a few basic areas to check, the shooter may avoid colsiderable frustration, not to mention time, expensive loading components and barrel wear.
Is your well-built rifle of high-quality components plagued with vertical fliers across more than 1-3 handload combinations? Consider the bedding, crown and scope/sight mounts. Are they correct? If so, then you might check for ignition issues before boldly undertaking an extensive, expensive, and quite possibly fruitless quest for the “magic handload”.
SEEING IS BELIEVING: While the author had been aware for many years that poor ignition should be considered and ruled out when dealing with vertical fliers in an otherwise-excellent rifle, actually seeing the problem and its almost instantaneous cure really drove the lesson home.
He was working with a “dot” rifle – a .22 LR match rifle that really stacked bullets into little piles at 50 yards and beyond. With one lot of ELEY Tenex, it produced consistent “bughole” groups at 50, but with another, selected lot of Tenex, similar groups were regularly ruined by single, vertical fliers that did not appear in other rifles. Rather than spending days burning up expensive, select ammunition looking for “magic lots”, he contacted a well-respected rimfire gunsmith and explained the situation.
Without so much as batting an eye, the highly-experienced ‘smith tore into the rifle’s action, and quickly found the cause(s) of the problem. He discovered a demonstrably weak firing pin spring, plus a chip out of the face of the firing pin where it contacted the cartridge rim.
After replacing and tuning the offending parts, the rifle immediately began shooting tiny, bughole groups with the previously “unacceptable” lot of Tenex. Centerfire rifles can also benefit from ensuring positive, consistent ignition. A wise riflesmith is literally worth his weight in gold!
So, what are some issues we as shooters can inspect in our rifles to help determine if ignition woes could be part of our problem? At the club level, ask yourself if that “experienced” Remington, Winchester 70, or even Springfield-based match bolt gun you’re using is still running its’ original 40-80 year-old factory striker spring? If so, a new replacement is cheap insurance against current or future problems. (And BTW, it might be best to stick to the normal, factory-spec spring weight. A super-powerful spring can cause vertical, just as a weak one one can.) Along with that, a routine check for proper firing-pin protrusion is a quick preventive measure that can rule out potential issues.
Other areas to consider are the centering and consistency of the firing pin’s operation in the bolt. Admittedly, with the increasing use of precision-machined custom actions, this is becoming less an issue every day. Below is the firing pin assembly from a custom BAT action:
However, particularly with factory actions, a very quick and easy check is to remove the bolt, let the firing pin go forward, and look at the firing pin tip through the firing pin hole. Is the tip off-center in the hole, and possibly striking it as it moves forward? Is the hole out-of-round or burred from being struck repeatedly? If so, a trip to the riflesmith is likely in order.
Similarly, machining issues in the bolt/firing pin system can lead to rough and erratic firing pin movement, in which the firing pin drags against an internal surface of the bolt. In high-quality rifles these issues are relatively rare, but not unheard-of, and it takes mere minutes to rule them out. It may be worthwhile to remove the cocking piece/firing pin/spring assembly and look for any unusual gouges, dings, peening, burrs or signs of abnormal wear.
This task is especially easy with Winchester 70s, Springfields, and the similar Mauser 98s, involving little more than the push of a button and unscrewing the cocking piece assembly. This is just one of the many reasons these tried-and-true actions have earned such a loyal following in the field, among hunters who must maintain their rifles away from a shop.
Particularly with older rifles, watch for and remove excess grease (or even Cosmoline!) from both the firing pin assembly and inside the bolt. This can help improve firing pin speed and consistency. Other bolt-action designs may need a take-down tool or other measures.
As part of this inspection, AFTER ENSURING THE RIFLE IS UNLOADED, slowly cock the rifle, dry-fire, and repeat several times. Listen carefully near the action for inconsistency in the sounds it generates. Does the striker falling make the same sound each time? Do you hear or feel grinding upon operation? If so, where?
Be sure to check the operation of the cocking piece (bolt shroud), firing pin within the bolt shroud, the cocking piece cam and the rear of the bolt body where the cocking piece cam operates. As with our examination for abnormal wear marks discussed above, look for marks indicating roughness or a possible need for light polishing. Then, clean and lightly grease the bearing surfaces while you’re at it.

These are relatively easy checks that shooters can undertake to perform a preliminary inspection on their own. Other mechanical issues can also cause ignition issues, chiefly centered around the action of the trigger, sear and sear spring. If these are suspected, a trip to an experienced, qualified riflesmith for diagnosis is recommended. We hope you find this information helpful!

A customer of well-known gunsmith (and Hall-of-Fame shooter) Thomas “Speedy” Gonzalez recently asked Speedy about bedding compounds. Speedy offered some interesting advice based on long-term testing of various materials. Speedy favors Marine-Tex because it is very stable over time, while other materials can shrink up to 6% dimensionally. A good bedding job should be a perfect fit to your barreled action. If the bedding material shrinks over time, that is NOT a good thing….
Speedy’s customer asked: “I know you’re not a Devcon man in regards to bedding compounds but I respect your input in such matters and my question is this in regard to aluminum actions. If Devcon was considered, for an aluminum action, would you prefer aluminum compound formula or steel formula? I personally prefer Devcon steel and Marine-Tex for steel receivers but my experience with aluminum is limited. Also do you have a release agent preference that works better with aluminum?”
Speedy answered: “My only preference of one epoxy over another is their stability over time. My buddy who works for the Texas State Weights and Measures Department had me cast several of the most common types of epoxies used for bedding into 1.000″ machined blocks. After one year of being kept in a controlled climate and measured for shrinkage monthly, the Marine Tex shrunk only 1/10th of 1% (i.e. 0.1%) whereas almost all the others (including Devcon Steel formula, Devcon Aluminum formula…) shrunk 3% to 6%. The only other compounds that matched the Marine Tex were Araldite 1253 and Araldite 2014, with the latter being quite expensive for daily use.”
Speedy added: “The Marine Tex Grey has no atomized metal in its makeup even though it appears that it does. This can be proven by the use of a strong neodymium magnet. What is humorous to me is that people don’t like aluminum yet will bed their actions atop aluminum pillars that have twice the coefficient of expansion (COE) of steel. Like Devcon, it is what people have always done and used. Thus [they] perpetuate the same old stuff. That’s my two cents’ worth. But as I tell everyone, ‘I’ll tell you what I know or do, but it’s not my job to convince anyone to do it my way’.”
Release Agents — Try Shoe Polish
Regarding release agents, Speedy stated: “I use Kiwi Neutral or Tan shoe polish. This works great and you can find it anywhere. Do NOT use the black or brown as it will stick.”

Speedy notes, “The stock was a raw blank requiring full inletting for the action to fit properly plus the titanium block. All the loading ports, bolt handle cut, bolt stop, and trigger guard cuts were done with diamond tooling to eliminate fraying and/or delamination of the wood.” You’ll find more projects by Speedy on his Facebook Page. Speedy is in San Antonio, Texas now, and accepting new projects with his company S.G. Rifles LLC.
