Here’s a “must-read” article for .22 LR rimfire shooters. The recently-released October 2018 issue of Shooting Sports USA (SSUSA) includes a great article with data on thirty-one (31) different types of popular .22 LR rimfire ammunition. The line-up includes low-speed, standard, and Hi-Velocity types, plus choices for plinking, varminting, and target applications. Brands tested include: Aguila, American Eagle, CCI, Federal, Fiocchi, Lapua, Remington, and Winchester. The slowest ammo, CCI Quiet-22 Lead RN, clocked 727 FPS. The fastest ammo, CCI Short-Range Green Lead-Free HP, ran 1735 FPS, more than twice as fast as the Quiet-22.
For each ammo type, SSUSA lists the bullet weight, velocity (FPS), and average of two, 5-shot groups at fifty yards. The most accurate ammo was Lapua Center-X LRN, with a 0.37″ average 50-yard group size. Second best was Lapua X-ACT LRN at 0.42″. Ammo was tested from a bench with a Cooper Model 57-M rifle fitted with 3-9x33mm Leupold VX-2 scope. The ammo offerings were grouped into three categories: (1) Varmints/Small Game; (2) Target; and (3) Plinking. (See ammo tables below.)

Different types of .22 LR (Long Rifle) rimfire ammo have different applications. Subsonic ammo, typically, is best for 25m to 50m target work with precision rimfire rigs. Hi-Velocity .22 LR ammo provides a flatter trajectory for longer ranges. SSUSA explains: “The array of .22 LR loads… turns a person’s head every which way. Subsonic target loads are the key to decisive accuracy on targets, while hyper-velocity cartridges provide striking bullet expansion on small varmints. In between, standard and high-velocity .22 LRs are loadrf with a variety of bullet weights and styles for everything from small-game hunting to plinking[.]” READ Full SSUSA .22 LR Rimfire Ammo Story.

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.

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[.]”
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.
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.

Do You Like H4350? Then You Should Try Reloder 16 — It Is Accurate and Temp Stable
Alliant Reloder 16 is used now by many top shooters for cartridges that work well with Hodgdon H4350. In fact, we’d say that Reloder 16 is the best substitute for H4350 on the market. Alliant’s RL 16 is very temp stable, offers good velocity, and the accuracy is top tier. Some guys report slightly better accuracy than H4350 in the .284 Win, .260 Rem, 6.5 Creedmoor, 6mm Creedmoor, and 6XC cartridges. If you currently use H4350, you should definitely give Alliant Reloder 16 a try. The powder also boasts excellent lot-to-lot consistency and contains a proprietary de-coppering additive.
This is NOT just a slower version of Alliant’s double-based Reloder 15 (which words great in the 6mmBR and Dasher cartridges). Reloder 16 is a completely new formulation, produced in Sweden by Bofors for Alliant. Reloder 16 utilizes TZ technology, which manipulates the response of the propellant and resists the natural tendency to generate more pressure at higher temperatures and less pressure at lower temperatures. As a result, Alliant’s Reloder 16 offers truly outstanding temperature stability.
Match and Hunting Cartridge Applications:
Alliant tells us that Reloder 16 “is ideal for traditional hunting cartridges, such as .30-06 Springfield and .270 Winchester, as well as 6.5mm target loads and tactical applications wherein temperature stability is required.” We also think the powder will work well in these popular match cartridges: 6XC, 6mm Creedmoor, .243 Win, 6.5×47 Lapua, 6.5 Creedmoor, .260 Rem, .284 Win, and .300 WSM. For example, Alliant’s Reloder 16 Load Data Page shows a 2932 FPS load with Berger 130 grain Hybrid bullet in the 6.5 Creedmoor.

What kind of 200-yard accuracy can you get in an enclosed, underground test range? Would you believe 0.162 MOA at 200 yards with a .338? Have a look at these test targets from Sierra Bullets. Like most bullet manufacturers, Sierra does live-fire bullet testing to ensure that Sierra projectiles perform as promised, with repeatable accuracy. Sierra tests bullets in its own underground test complex. Sierra’s 300-meter test range is the longest, privately-owned underground bullet test facility in the Western Hemisphere. (RWS has a 500m test tunnel in Germany). Sierra offers free tours of the test tunnel as part of Sierra’s Factory Tour Program.
Day in and day out, various bullet types are tested using a big collection of barreled actions. These barreled actions are clamped in stout, return-to-battery test fixtures. These big, heavy test fixtures provide near-perfect repeatability (with no human-induced holding or aiming errors).
Sierra Bullets 10-Shot Groups at 200 yards
Check out these 10-shot test groups shot at the Sierra Test Range at 200 yards. Note that the numbers listed on each sample are actual measurements in inches. To convert to MOA, cut those numbers in half (to be more precise, divide by 2.094, which is 1 MOA at 200 yards). For example, the 0.340″ middle group works out to 0.162 MOA at 200 yards.
Scan-Verified 0.162 MOA Accuracy at 200 Yards
To verify the accuracy of Sierra’s measurements, we measured the middle (.338 caliber) 10-shot group with our On-Target Group Measurement software. We registered a group size reading of 0.339″ — within one-thousandth of the Sierra measurement*. The calculated group size in MOA (Minute of Angle) is 0.162. That’s amazingly good for ten rounds of big .338 caliber bullets. A FIVE-shot 0.162 MOA group at 200 would be considered excellent at any benchrest match. But remember this target has TEN shots. The current, one-target IBS world record for ten shots at 200 yards is 0.245″, set by Ed Watson in 1999.
Bevy of Barreled Actions for Bullet Testing
Sierra Bullets uses dozens of barreled actions for testing bullets in its enclosed, 200-yard test range. Each barrel has its own logbook to track the barrel’s usage.

*Note, there were ten (10) shots in the group, but for simplicity we are only displaying five (5) shot circles. Adding more circles won’t change the measurement because the two most distant shots, which determine group size, ARE included.
Do you need to pull bullets that have been seated in a case? You can use lever-actuated, collet-type pullers, or inertial hammer-style pullers, but there is a faster solution. The Grip-N-Pull bullet puller is a precision-machined hand clamp that works for multiple calibers. A single Grip-N-Pull can replace several other tools, while being faster to use. With larger-diameter bullets loaded with light-to-moderate neck tension, it works well. The bullets come out pretty easily, with no scuff marks or dents. For smaller-diameter, .204 to .243 caliber bullets, it may be hard to grip the bullet easily, or you may end up with some jacket damage. And we wouldn’t use this for factory-crimped cartridges.
Introduction to Grip-N-Pull — How It Works:
How to Use the Grip-N-Pull
Put your loaded case in the shell-holder on a reloading press. Raise the ram so the bullet is exposed at the top of the press. Then select the correct, caliber-specific slot in the Grip-N–Pull, clasp the bullet firmly, then lower the ram. The bullet withdraws from the case-neck, retained in the tool. Fast and simple. If there isn’t much neck tension (or a crimp), the bullet should come out undamaged.
Not So Great for Small-Diameter Bullets
Watch this video — the tester says the Grip-N-Pull works well with larger-diameter bullets, but there can be slippage with smaller-diameter projectiles, or those with short bearing surfaces. NOTE: When there is a lot of neck tension, you have to grip extremely hard which can cause your hand to hurt after a while. And the bullets can get marred.
This video explains some of the shortcomings of the Grip-N-Pull.
Four Grip-N-Pull Models Available Grip-N-Pull bullet pullers can be used for multiple calibers. For example, the Standard Rifle Grip-N-Pull pulls bullets for these calibers: .17, .20, .22, .24, .25, .26, .27, .28, and .30. The Large Rifle model works with 8mm, .338, .375, .416 and .458. There is a third model for pistol cartridges, and a fourth “Mil-Spec” unit that does 5.56, 7.62, .338 and .50 BMG. Grip-N-Pull bullet pullers are made of 1/4″ heavy-duty #30 stainless steel and are backed by a lifetime warranty.
Speed and Efficiency of Grip-N-Pull
The Grip-N-Pull’s creators claim this hand clamp cuts bullet pulling time in half. For a speed comparison between Grip-N-Pull and a hammer-style (inertial) bullet puller, watch this Extreme Outer Limits video. Bob and Chris Beck do a head-to-head comparison between the Grip-N-Pull and an inertia puller. It’s no contest — the Grip-N-Pull is way faster, and the powder stays in the case.
Pull Comparison — Grip-N-Pull Vs. Hammer-Style Inertial Puller
User Review by Tommy Todd
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.
