Sierra Secrets — How MatchKings Are Made

Sierra Bullets Carroll Pilant MatchKing Bullet SMK Bullet-making Jacket

The Making of MatchKings — How Sierra Produces SMKs
All Sierra bullets begin life as a strip of gilding metal, an alloy consisting of 95% copper and 5% zinc. To meet Sierra’s strict quality requirements, the gilding metal requires three times more dimensional and quality control standards than is considered standard in the copper manufacturing industry.

A blanking press stamps out a uniform disc and forms the cup that will be drawn into the MatchKing jacket. The cup is then polished and sent to a draw press to be drawn into a jacket that is longer than needed for the future MatchKing, thus allowing for the trim process. Press operators constantly check concentricity to make sure we have only quality jackets. The jackets then go to a trimmer where they are visually inspected again.

After being polished a second time, the jacket travels to the bullet press. In the meantime, 80-pound lead billets are being extruded into lead wire for the cores where great care is taken so that the core wire is not stretched. The core wire is lightly oiled before continuing to the bullet press to be swaged.

The lead core wire and trimmed jacket meet at the bullet press where the first stage forms a boattail on the jacket. The lead core is then formed on top of the bullet press and fed down into the jacket. In one stroke of the press, the MatchKing is formed.

Quality control technicians pull samples from each lot of MatchKings to make sure they meet Sierra’s stringent standards. Samples are then sent to Sierra’s 300-meter underground test range (shown below) to be shot for accuracy on mechanical mounts referred to as “unrestricted return to battery rests” that Sierra designed and built in-house.

After inspection, the bullets are placed in the familiar green box along with reloading labels. They are then shrink-wrapped and shipped all over the world.

6.5 Creedmoor Cartridge Reloading INFO — Load Data from Sierra

Sierra Load Data 6.5 Creedmoor

Sierra Bullets has released very complete load data for the popular 6.5 Creedmoor cartridge. This medium-sized cartridge has become one of the most popular chamberings for tactical and PRS shooters. The 6.5 Creedmoor combines excellent accuracy, good mag-feeding, good barrel life, moderate recoil, and reasonable component cost. That’s why this cartridge has caught on quickly.

Sierra Load Data 6.5 CreedmoorDeveloped in 2007 by Dennis DeMille and Dave Emary, the 6.5 Creedmoor is a shortened and improved 30 TC cartridge case that was inspired by the .308 Winchester design. This short action design was created to maximize case capacity and a wide range of loading lengths, while still fitting in standard short action magazines. With the correct twist barrel, the versatile 6.5 Creedmoor can take advantage of the wide range of bullet weights available in 6.5 mm (i.e. .264 caliber). Reloaders should keep in mind that the 6.5 Creedmoor works best with medium to medium-slow powders such as H4350, Varget, Win 760, and RE-17. The light recoil and adaptability of the efficient 6.5 Creedmoor cartridge has already proven itself in high power, precision rifle series and benchrest competitions. Couple that with respectable barrel life and its intrinsic accuracy potential and you have a recipe for success which should insure its legacy for decades to come.

Here are three tables from the Sierra Bullets Reloading Manual (5th Edition). IMPORTANT — This is just a sample!! Sierra has load data for many other 6.5mm bullet types, including FB, Spitzer, SBT, HPBT, and Tipped MK from 85 grains to 142 grains. To view ALL 6.5 Creedmoor DATA, CLICK HERE.

NEW — Ultra-High BC 150-Grain 6.5mm MK from Sierra

Sierra Bullets MatchKing 150 grain 150gr high BC G1 G7 6.5 Creedmoor

Up until now, 147 grains was the high end of 6.5 mm (.264 diameter) match bullets offered by major bullet-makers. Now Sierra has “raised the bar” — releasing a 150-grainer with a killer 0.713 G1 Ballistic Coefficent (BC). You read that right — 0.713! Compare that to the 0.626 G1 BC for Sierra’s well-known 142gr MatchKing, 0.697 for the Hornady 147gr ELD Match, and 0.607 for the Berger 140gr Hybrid Target. To increase (and uniform) the BC, Sierra’s new 150-grainer is pointed at the factory. Recommended barrel twist rate is 1:7.5″.

CLICK HERE for 6.5 Creedmoor LOAD DATA for this new 150gr Matchking.

Sierras’ product announcement states: “Shooters … will appreciate the accuracy and extreme long range performance of our new 6.5 mm 150 grain HPBT (#1755). A sleek 27-caliber elongated ogive and a final meplat reducing operation (pointing) provide an increased ballistic coefficient for [reduced wind drift] and velocity retention. To ensure precise bullet-to-bore alignment, a unique bearing surface-to-ogive junction uses the same 1.5-degree angle commonly found in many match rifle chamber throats. This bullet requires a twist rate of 1:7.5″ or faster to stabilize.”

Sierra’s new 6.5 mm 150 grain HPBT MatchKing bullet is available in 100-count boxes (#1755) for $50.98 MSRP, and 500-count boxes (#1755C) for $226.45 MSRP.

Sierra Offers New Ultra-High-BC 197gr 7mm (.284) MatchKing

Sierra 197gr MatchKing High BC F-Open Closed Meplat

Get ready for a revolution in the F-Open, ELR, and Long-Range Benchrest games. Sierra just introduced a new 7mm bullet with a stunning 0.780 G1 BC. This new 197-grain HPBT MatchKing is one of the highest-BC, jacketed .284-caliber projectiles ever offered to the public. By comparison, Sierra’s own advanced 183-grain 7mm Matchking has a .707 G1 BC. That means the new 197-grainer has a 10% higher BC than the already slippery 183-grainer. That’s an impressive achievement by Sierra.

We expect top F-Open and long-range shooters will be trying the new 197-grainer as soon as they can get their hands on this new projectile. They may need new barrels however, as Sierra states: “This bullet requires a barrel twist rate of 1:7.5″ or faster”. Sierra expects to start shipping these slippery 7mm 197s very soon. You can order directly from Sierra’s website, stock code #1997, $54.20 for 100 bullets.

Sierra 197gr MatchKing

Factory Uniformed Bullet Tips
Sierra has officially announced that the 197gr SMK will come “pointed” from the factory. These impressive new 197s will have a “final meplat reducing operation” (pointing). This creates a higher BC (for less drag) and also makes the BC more uniform (reducing vertical spread at long range). Our tests of other factory-pointed Sierra MKs have demonstrated that Sierra does a very good job with this pointing operation. The “pointed” MatchKings we’ve shot recently had very nice tips, and did hold extremely “tight waterline” at 1000 yards, indicating that the pointing process does seem to enhance BC uniformity. Morever, radar-derived “real-world” BCs have been impressively uniform with the latest generation of pointed Sierra MKs (such as the new 110gr 6mm MatchKing).

Here is the statement from Sierra about the new bullets:

Shooters around the world will appreciate the accuracy and extreme long range performance of our new 7mm 197 grain HPBT (#1997). A sleek 27-caliber elongated ogive and a final meplat reducing operation (pointing) provide an increased ballistic coefficient for optimal wind resistance and velocity retention. To ensure precise bullet to bore alignment, a unique bearing surface to ogive junction uses the same 1.5 degree angle commonly found in many match rifle chamber throats.

While they are recognized around the world for record-setting accuracy, MatchKing® and Tipped MatchKing® bullets are not recommended for most hunting applications. Although MatchKing® and Tipped MatchKing® bullets are commonly used for varmint hunting, their design will not provide the same reliable explosive expansion at equivalent velocities in varmints compared to their lightly jacketed Hornet, Blitz BlitzKing, or Varminter counterparts.
