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.
Remington 700 bolt shroud and cocking cam
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! Join us again next week, and in the meantime, enjoy the shooting sports safely!

We know some guys who make their own stocks, and others who do their own chambering. But consider this, Robert Carnell of Australia built his own state-of-the-art, water-cooled, tension-barrel Rail Gun, even including the action. That’s right, Robert even made his own action. Wow, this has to be the ultimate home gunsmithing, do-it-yourself project.
Carnell is an accomplished benchrest shooter and past Australian Sporter Class Champion. In 1993 he won a Silver Medal at the World Championships. But Carnell is far more than an ace trigger-puller. Robert is a skilled and creative “home gunsmith” who has crafted his own custom action and built his own railguns from scratch. Robert also runs the Austrialian Benchrest Bulletin website.
Home-Built Rail Gun — Aussie Innovation
Below are photos of one of Rob Carnell’s most amazing builds. This liquid-cooled, tension-barrel rail gun is a great example of self-reliant Aussie engineering. The barrel runs inside a coolent-filled, large-diameter sleeve, much like an old water-cooled machine gun. This is the fourth rail gun that Rob built, and the second fitted with a tensioned barrel.
Robert explains: “My railgun design has a 1.75″ barrel under tension inside an aluminium tube filled with radiator coolant. There is nearly a gallon of coolant, and the barrel stays cool no matter how many shots I seem to fire, or how quickly they are shot. The brass nut on the front rides on a nylon bearing and can be tightened to get the best accuracy. I am a believer in the ‘tuner’ idea and this seems to work for me. The main tube is thick-walled aluminium 600mm (24″) long. There is a flange at both ends. The flange at the back fits onto the barrel before the action is screwed on. The front flange is a press-fit into the tube, then there is a brass nut that fits over the barrel and screws against a nylon washer on the front flange. The Railgun’s base is aluminium and has the standard adjustments — windage, elevation and a sighter cam. In addition, there is a 1/10 thou dial indicator for windage. This allows me to zero the indicator and shoot my group. If I need to add a bit of windage for a condition, I can quickly get back to the original position if my condition comes back.”
Home-Built Action Uses Rem Bolt
Rob’s rail gun uses his own home-made stainless action, which features Panda-spec threads and a modified Remington 700 aftermarket bolt. Not bad for a do-it-yourself project we’d say! CLICK HERE to read how Rob designed and built the action.

Tonight (12/7/2016), Shooting USA television features the Remington Bicentennial — celebrating 200 years of continuous production by one of America’s most legendary companies. The history of Remington Arms is a remarkable story. No large American enterprise — not Ford, not General Motors — can match the 200-year continuous history of Remington. The Remington enterprise is nearly as old as the United States. This story began in 1816, when a young man, Eliphalet Remington II, wanted a rifle…
According to historians, Eliphalet told his father he wanted a gun, so his father told him to build one himself (Eliphalet had been trained as a blacksmith). And so, in 1816, Eliphalet did just that, with the help of a hired gunsmith to bore and rifle his barrel. Eliphalet then took the finished flintlock to a local shooting match. “And his gun shot well,” says Remington Historian Richard Shepler. “So neighbors and friends asked, ‘Could you make me a barrel?’ Over time there was more and more demand.”
By 1828, Eliphalet moved into a factory in Illion, New York. In 1845, he jumped at the opportunity to secure the first of many government contracts. When the Civil War broke out, Remington stayed busy producing firearms. While later in the 1890s during peacetime, Remington manufactured cash registers, sewing machines, knives and even the first successful typewriter.
Whether fulfilling government contracts during wartime, or manufacturing cash registers and sewing machines during peacetime, Remington’s story continues today, arming sportsmen, hunters and armies around the world.

This week, American Rifleman TV looks at the history and heritage of Remington, which celebrates its 200th Anniversary this year. Founded in 1816, Remington is the oldest continuously-operating gun manufacturer in the United States, and it still sells more sporting rifles and shotguns than any other American company. Remington has also developed more cartridges than any other U.S. company. If you want to learn more about this important arms-maker, watch tonight’s episode, which you can preview below.
Two Hundred Years of Gun-Making Remington Arms Company celebrates its 200th year in business in 2016. The Remington enterprise was founded in 1816 by Eliphalet Remington in Ilion, New York, as E. Remington and Sons. Remington is America’s oldest gun maker and is still the largest U.S. producer of shotguns and rifles. And it is the only American Company that sells firearms and ammunition under its own name. CLICK HERE for 200 facts about the 200-year-old company.
American Life in 1816
What was life like in America in 1816, two hundred years ago? This infographic offers some interesting facts. For example, average life expectancy was only 39 years, and a farm laborer earned just $12-$15 per month. Still want to go back to the “good old days”?

You probably know by now that David Tubb has introduced a new two-stage trigger for Remington 700 rifles, the Model T7T. Priced at $385.00, the new T7T Trigger is a true two-stage design: first and second stages are independently adjustable for both weight and feel. Overall (combined stage) trigger pull weight can be adjusted from just under 1 pound to slightly over 3.5 pounds.
If you are interested in the 7ZT, watch these two videos. The first shows how to adjust pull-weights for both stages. The second video shows how to modify your stock to provide clearance for the T7T.
This video shows how to adjust the new Tubb T7T two-stage trigger for Remington 700s:
The new T7T is a quality product. We’ve received good feedback from “early adopters” who tell us the two-stage function works well. While installation of the T7T may require minor modifications to your action, most gun owners with basic mechanical skills can install the T7T by themselves. The T7T is made using stainless steel and aluminum for maximum corrosion resistance. Note, installation of the T7T trigger (either Right-Hand or Left-Hand) also requires a companion T7T bolt release, offered by DavidTubb.com for $10.00.
