Photo 1: Three Near-Equal-Weight 7mm Bullets with Different Shapes
TECH TIP: Bullets of the same weight (and caliber) can generate very different pressure levels due to variances in Bearing Surface Length (BSL).
Bullet 1 (L-R), the RN/FB, has a very slight taper and only reaches its full diameter (0.284″) very near the cannelure. This taper is often seen on similar bullets — it helps reduce pressures with good accuracy. The calculated BSL of Bullet 1 was ~0.324″. The BSL of Bullet 2, in the center, was ~0.430”, and Bullet 3’s was ~ 0.463″. Obviously, bullets can be visually deceiving as to BSL!
This article from the USAMU covers an important safety issue — why you should never assume that a “book” load for a particular bullet will be safe with an equal-weight bullet of different shape/design. The shape and bearing surface of the bullet will affect the pressure generated inside the barrel. This is part of the USAMU’s Handloading Hump Day series, published on the USAMU Facebook page.
Beginning Handloading, Part 13:
Extrapolating Beyond Your Data, or … “I Don’t Know, What I Don’t Know!”
We continue our Handloading Safety theme, focusing on not inadvertently exceeding the boundaries of known, safe data. Bullet manufacturers’ loading manuals often display three, four, or more similar-weight bullets grouped together with one set of load recipes. The manufacturer has tested these bullets and developed safe data for that group. However, seeing data in this format can tempt loaders — especially new ones — to think that ALL bullets of a given weight and caliber can interchangeably use the same load data. Actually, not so much.
The researchers ensure their data is safe with the bullet yielding the highest pressure. Thus, all others in that group should produce equal or less pressure, and they are safe using this data.
However, bullet designs include many variables such as different bearing surface lengths, hardness, and even slight variations in diameter. These can occasionally range up to 0.001″ by design. Thus, choosing untested bullets of the same weight and caliber, and using them with data not developed for them can yield excess pressures.
This is only one of the countless reasons not to begin at or very near the highest pressure loads during load development. Always begin at the starting load and look for pressure signs as one increases powder charges.
Bullet bearing surface length (BSL) is often overlooked when considering maximum safe powder charges and pressures. In photo 1 (at top), note the differences in the bullets’ appearance. All three are 7mm, and their maximum weight difference is just five grains. Yet, the traditional round nose, flat base design on the left appears to have much more BSL than the sleeker match bullets. All things being equal, based on appearance, the RN/FB bullet seems likely to reach maximum pressure with significantly less powder than the other two designs.
Bearing Surface Measurement Considerations
Some might be tempted to use a bullet ogive comparator (or two) to measure bullets’ true BSL for comparison’s sake. Unfortunately, comparators don’t typically measure maximum bullet diameter and this approach can be deceiving.
Photo 2: The Perils of Measuring Bearing Surface Length with Comparators
In Photo 2, two 7mm comparators have been installed on a dial caliper in an attempt to measure BSL. Using this approach, the BSLs differed sharply from the original [measurements]. The comparator-measured Bullet 1 BSL was 0.694” vs. 0.324” (original), Bullet 2 was 0.601” (comparator) vs. 0.430” (original), and Bullet 3 (shown in Photo 2) was 0.602” (comparator) vs. 0.463” (original). [Editor’s comment — Note the very large difference for Bullet 1, masking the fact that the true full diameter on this bullet starts very far back.]

Gunsmith Darrell Holland sells a priming tool that upgrades the RCBS Auto Bench Priming Tool with key features — including primer seating depth control. If your hand starts to hurt after priming dozens of cases with a hand-held, squeeze-type priming tool, you may want to consider Holland’s invention, which he calls the “Perfect Primer Seater” (PPS).
Holland basically has modified the RCBS lever, adding a precise crush control and a means of measuring depth with a gauge. He claims this gives “an EXACT primer seating depth based on primer pocket depth and primer thickness”. With Holland’s PPS, primer seating depth is controlled with a rotating wheel that limits lever travel in precise gradations. You can buy the complete priming system for $215.00, or, if you already own the RCBS Auto Prime tool, you can purchase an adapter kit (with base, arm, adjuster, and gauge etc.) for $120.00. To order, visit Hollandguns.com. Click on “Reloading Equipment”, and look for the Perfect Primer Seater. Scroll down to the bottom of the page to add items to the shopping cart.
User Review by Tommy Todd
Sierra Bullets’ Chief Ballistician Tommy Todd acquired the Holland Perfect Primer Seater, and gave it a positive review. Todd writes: “This cartridge case priming system allows you to measure the primer pocket depth and adjust the seating tool to match the primer seating depth for a contact fit with a measured lot of primers to the cases you are working with. Mr. Darrell Holland has taken a standard RCBS automatic bench-mounted priming tool and modified it to a new level of precision. The modifications allow you to measure the primer pocket depth, primer height, and with the addition of an adjustable stop on the priming tool achieve precision primer seating, rather than how the primer ‘feels'[.]
If you are already utilizing the RCBS priming tool, Mr. Holland offers an adapter kit to upgrade your equipment. If you are looking for a new priming unit, I suggest giving this product a try. Increasing consistency when seating primers should result in smaller groups[.]”

If you’ve never been to a benchrest match, visit the IBS website to find an affiliated club in your area. You’ll find schedules for upcoming events where you can learn about the sport.
This article describes an impressive complete benchrest rifle that will be awarded next month to an IBS competitor in the IBS Southeastern Region. This premium benchrest rig was a collaborative effort, with components and build labor donated by many companies. The rifle and scope prize will be awarded at a Banquet on November 10, 2018. The winner will be chosen from shooters who have accumulated “tickets” (essentially prize credits) over the course of the year. Tickets are earned through match attendance and shooting performance: 1 ticket for each match attended in the SE region ranges listed above (AFTER attending five matches). Shooters get additional tickets for a perfect 2,500 score, plus 10 additional tickets for attending at least one match at each and every participating range.
A Magnificent Prize
by Boyd Allen, IBS Vice President
Coming up with prizes for shooting events is always a challenge, and results can vary considerably from match to match. This rifle is at the apex of the prize pyramid. Few complete rifles are seen on prize tables, because of their cost, and because they are generally built to order from select components, produced by multiple manufacturers. There are no off-the-shelf benchrest rifles, and if there were, the price of one, complete with a quality scope, would be too great to ask of a single source, given the size of the typical businesses that serve this sport.
Any score shooter would be glad to have this rifle and feel quite fortunate to win it. It is a fine example of its type, made of top components, and stocked with a “Indian Blanket” pattern Obeche laminate that will not be seen again once the supply runs out, because the factory that produced it burned down. As you would expect for this type of competition, it is chambered for the 30 BR.
This prize rifle was built to increase interest and participation in centerfire score shooting in the Southeast Region of the International Benchrest Shooters (IBS), as well as to encourage competitors to visit more ranges and attend more IBS matches. Ranges participating in this prize campaign are:
Bluegrass Sportsmen’s League (Wilmore, KY), Buck Creek Gun Club (Somerset, KY), Georgia Mountain Shooting Association (Eastanollee, GA), Mid-Carolina Gun Club (Orangeburg, SC), Piedmont Gun Club (Rutherfordton, NC), and Palmetto Gun Club (Ridgeville, SC).
Good luck to everyone for the remainder of the 2018 season. NOTE: There are more detailed rules than we can reproduce here (for space reasons). If you intend on taking a serious run at this prize, take the time to inquire about all of the specifics.
Left to Right: Jim Cline, Doyle Anglin, and Ronnie Milford.
Background of the IBS Rifle Prize
Ronnie Milford explained: “Near the completion of the Southeastern Regional, I [asked] some of our fellow shooters about increasing participation. One of them suggested that we have one big prize that would be participation-based. I ran the idea of building a complete rifle by my personal gunsmith Doyle Anglin. He warned me that he had seen others try to do the same thing, and that it would be hard to get people to donate products. That lit a fire. First phone call was to Jim Kelbly who offered to donate the action. For the trigger Jim recommended a Bix & Andy from Chris at Bullet Central. I then called Jim Cline, and he got Brux to donate the barrel. Then, I talked to my NightForce contacts, Allen Stillwell and Wayne Dayberry. They donated a competition scope.
My next phone call was back to Doyle Anglin and I told him what had been donated. He then talked about ‘fitting and chambering, pillar bedding, and stock by Dixie Guns’. When Dave Short heard what we were doing, he donated a trigger guard, chamber cleaning kit, and a barrel tuner. Jim called Linwood Harrell who donated our scope rings. We were almost complete, and I told them that I would spray the finish on the stock. When this news got out, it caused a great deal of excitement.”
Prize Rifle Eligibility and Award Procedures
This custom rifle will be given away at the awards banquet on November 10, 2018 in Orangeburg, SC. The winner will be chosen using tickets earned during the season. A shooter will “earn” 1 prize chance ticket for each match attended in the SE region ranges listed above, AFTER attending five (5) matches. (If you attend four matches or less you will receive 0 tickets for attendance.) You can get 5 additional tickets for a perfect 2,500 score and 10 additional tickets for attending one match minimum at each participating range. We will keep track of the tickets earned and they will be passed out at the banquet for you to personally place them in the container.
Prize Rifle Being Constructed at Doyle Anglin and Ronnie Milford shops:
Support the Sponsors — This is a very impressive prize. Keep the generosity of all who donated to the project in mind the next time that you are in the market for products they make or sell. In the future we may offer a follow-up story about the rifle winner and his/her first competition with this 30 BR benchrest rifle. In any case, on November 10, 2018, someone is going to be very happy with their valuable prize.
Built to Shoot — Remember this rifle was created by donations, to grow the sport, and promote shooting, not to sell for monetary gain. If you do not plan on shooting this rifle, please donate it to an upcoming shooter. Ronnie Milford, and Jim Cline worked hard to make this dream become a reality. Let’s not let down the sponsors who continue to support us.

Western Powders (which sells Accurate, Ramshot, and Norma powders) has published an article on case inspection and preparation. There are many tips in this article that can be useful to precision hand-loaders. For example, every time you open a new box of cartridge brass (particularly from domestic makers), you should inspect each case for flaws.
TIP ONE: Visual Inspection — Finding Flaws
Cases are mass-produced items and malformed ones are relatively common. Inspect each case carefully looking for obvious defects. A bench-mounted magnifying glass with light is a real help for the over-40 crowd. The main defects will be cracks in the neck or case body, crushed shoulders or deep creases in the neck. Next check the primer pocket. It is also fairly common to find flash holes that are damaged or, more rarely, not concentric to the primer pocket.
Imperfections like small dings in the case body, or necks that are not completely symmetrical do not have to be eliminated at this step. Damage of this sort is usually from loose packaging and usually has not seriously damaged the brass. [Running an expander mandrel in the neck] and fire-forming will iron out these largely cosmetic issues.
The Western Powder article also talks about primer pocket uniforming. We do NOT normally uniform the pockets for Lapua or RWS brass from the start. However, pocket uniforming can be beneficial with some other brands of brass, including Lake City, Remington, and Winchester. If you shoot milsurp brass, set time aside for pocket uniforming.
TIP TWO: Primer Pocket Uniforming
Like flash holes, primer pockets are mass-produced and prone to small dimensional changes. A uniforming tool is used to make the depth of each primer pocket consistent. In turn this allows similar firing pin strike depths on the primer which creates more consistent ignition characteristics.
A good uniforming tool should have a shoulder, or another positive stop, that sets the cutter’s depth. Its use is pretty straightforward. The cutter is inserted into the pocket and turned clockwise several times until the stop in flush with the case head and no more brass is removed from the juncture of the pocket’s base and sidewall. This a job best done by hand. You will feel when the cutting is finished by a change in how smoothly the cutter turns in the pocket. Very little material is actually removed; usually just enough to square the radius at the bottom of the pocket.

Do you have a family member who has recently acquired his or her first firearm? Do you have friends or neighbors who keep firearms in a home with small children? It is important to know and practice the principles of firearms safety, ALL the time. Here are two well-written gun safety manuals in printable PDF format. All firearms owners, even experienced hunters and competitors, can benefit from reviewing these resources from time to time. And new gun owners, in particular, should take the time to read both these guides. The Remington Safety Manual includes the “Ten Commandments of Firearms Safety”. Here’s the First Commandment:

We are often asked “Can I get more velocity by switching primer types?” The answer is “maybe”. The important thing to know is that changing primer types can alter your load’s performance in many ways — velocity average, velocity variance (ES/SD), accuracy, and pressure. Because there are so many variables involved you can’t really predict whether one primer type is going to be better or worse than another. This will depend on your cartridge, your powder, your barrel, and even the mechanics of your firing pin system.
Interestingly, however, a shooter on another forum did a test with his .308 Win semi-auto. Using Hodgdon Varget powder and Sierra 155gr Palma MatchKing (item 2156) bullets, he found that Wolf Large Rifle primers gave slightly higher velocities than did CCI-BR2s. Interestingly, the amount of extra speed (provided by the Wolfs) increased as charge weight went up, though the middle value had the largest speed variance. The shooter observed: “The Wolf primers seemed to be obviously hotter and they had about the same or possibly better ES average.” See table:
Varget .308 load |
45.5 grains |
46.0 grains |
46.5 grains |
CCI BR2 Primers |
2751 fps |
2761 fps |
2783 fps |
Wolf LR Primers |
2757 fps |
2780 fps |
2798 fps |
Speed Delta |
6 fps |
19 fps |
15 fps |
You can’t extrapolate too much from the table above. This describes just one gun, one powder, and one bullet. Your Mileage May Vary (YMMV) as they say. However, this illustration does show that by substituting one component you may see significant changes. Provided it can be repeated in multiple chrono runs, an increase of 19 fps (with the 46.0 grain powder load) is meaningful. An extra 20 fps or so may yield a more optimal accuracy node or “sweet spot” that produces better groups. (Though faster is certainly NOT always better for accuracy — you have to test to find out.)
WARNING: When switching primers, you should exercise caution. More speed may be attractive, but you have to consider that the “speedier” primer choice may also produce more pressure. Therefore, you must carefully monitor pressure signs whenever changing ANY component in a load. Glen Zediker recommends decreasing your load ONE FULL GRAIN when changing to a different primer type, one that you haven’t used before.

For more information, visit www.initiative1639.org.
Once again a serious threat to citizens’ Second Amendment rights is coming from the Left Coast. If you live in Washington State, you need to educate yourself on Initiative 1639 (I-1639), a THIRTY-page gun control measure on the November ballot. This is one of the most restrictive and radical gun measures ever put on a State ballot. Your vote is needed to block I-1639 from becoming law.
This measure basically defines virtually ALL self-loading long guns as “assault rifles”. This would even include popular .22 LR rimfire rifles such as the Ruger 10/22, Marlin 60, and Remington 597. In addition, I-1639 imposes draconian gun storage requirements, imposes new taxes on gun ownership, creates a far-reaching gun registry, and mandates annual “verification” of gun owners. LEARN MORE HERE*.
“Law enforcement professionals recognize the extreme nature of I-1639,” said Alan Gottlieb, chairman of the Citizens Committee for the Right to Keep and Bear Arms. “Not only does the initiative discriminate against gun owners, it classifies common recreational firearms as ‘semiautomatic assault rifles’ and requires gun buyers to surrender their medical privacy in order to exercise a constitutionally-protected right.” I-1639 is being pushed by the Seattle-based Alliance for Gun Responsibility, an extreme anti-gun advocacy group funded by billionaire dollars.
Not just organized gun rights groups are opposing I-1639. In fact many Washington State law enforcement organizations have opposed this far-reaching anti-gun measure.
The Washington State Sheriffs Association (WSSA), Washington Council of Police & Sheriffs (WACOPS) and Washington State Law Enforcement Firearms Instructors Association (WSLEFIA) all oppose I-1639.
The WSLEFIA stated: “Initiative 1639 is being promoted as a public safety measure; those actually working law enforcement know that IT WILL DO NOTHING TO STOP A SINGLE CRIME. This initiative has nothing to do with ‘assault weapons’ and is directed only at our good citizens who already pass multiple background checks before owning a firearm. I-1639 is an attack on civil rights and is an attempt to marginalize all firearm owners, including law enforcement officers. I-1639 will impair public safety, embolden criminals and impose burdensome restrictions on our most law-abiding citizens.”
Photo Courtesy NRA-ILA which opposes I-1639. See Initiative1639.org.
WACOPS Executive Director Teresa Taylor added, “WACOPS believe that Initiative 1639 contains provisions that are in clear violation of both state and federal individual constitutional rights, which, as law enforcement, officers, WACOPS members are sworn to uphold. In addition to the constitutional issues, this 30-page initiative, if passed, would impose significant restrictions on a citizen’s ability to possess and access commonly-owned firearms for lawful self-defense.”
* Furthermore, according to the NRA: “The Washington Department of Licensing (DOL) and law enforcement agencies are directed to collect and store information on purchases and transfers of guns under this Initiative, without limits on how this information may be used. Besides putting sensitive personal data at risk, this opens the door to a government registry of guns and gun owners. The Initiative also directs law enforcement agencies and the DOL to develop a process to ‘verify, on an annual or more frequent basis’, that both handgun and SAR owners continue to be eligible to possess any firearm under state and federal law. It authorizes law enforcement to ‘take steps to ensure’ that anyone who fails the verification process no longer possesses guns. The Initiative doesn’t rule out seizure and confiscation of firearms as means of enforcing this directive.”

Here’s a simple modification that makes your classic beam balance more user-friendly. For a few dollars you can enhance your balance scale system to improve work-flow and reduce eye strain. This clever modification makes it easier to see the balance’s zero-mark center-line when weighing charges.
When he chooses to measure his loads or sort bullets by weight, Forum Member Boyd Allen likes his trusty RCBS 10-10 scale. He finds that it works predictably, time after time, and it doesn’t suffer from the drift and calibration issues that plague some of the less-expensive electronic scales on the market.
To make it easier to see the balance point, Boyd has adapted a magnifying glass with a mirror. This makes the end of his balance beam easier to view from his normal position on the bench. Boyd explains: “This set-up uses a cheap magnifier with positioning arms that was probably designed to hold and magnify small objects while soldering them. I think that it came from Harbor Freight many years ago. The mirror lets you look at the scale as if is was at eye level, and of course the magnifier makes the image easier to see.”
