Bullet Spinning Fast Enough? Use Berger Twist Rate Calculator

Berger twist rate calculator

Berger twist rate calculatorBerger Twist-Rate Stability Calculator
On the Berger Bullets website you’ll find a handy Twist-Rate Stability Calculator that predicts your gyroscopic stability factor (SG) based on mulitiple variables: velocity, bullet length, bullet weight, barrel twist rate, ambient temperature, and altitude. This cool tool tells you if your chosen bullet will really stabilize in your barrel.

How to Use Berger’s Twist Rate Calculator
Using the Twist Rate Calculator is simple. Just enter the bullet DIAMETER (e.g. .264), bullet WEIGHT (in grains), and bullet overall LENGTH (in inches). On its website, Berger conveniently provides this info for all its bullet types. For other brands, we suggest you weigh three examples of your chosen bullet, and also measure the length on three samples. Then use the average weight and length of the three. To calculate bullet stability, simply enter your bullet data (along with observed Muzzle Velocity, outside Temperature, and Altitude) and click “Calculate SG”. Try different twist rate numbers (and recalculate) until you get an SG value of 1.4 (or higher).

Gyroscopic Stability (SG) and Twist Rate
Berger’s Twist Rate Calculator provides a predicted stability value called “SG” (for “Gyroscopic Stability”). This indicates the Gyroscopic Stability applied to the bullet by spin. This number is derived from the basic equation: SG = (rigidity of the spinning mass)/(overturning aerodynamic torque).

If you have an SG under 1.0, your bullet is predicted not to stabilize. If you have between 1.0 and 1.1 SG, your bullet may or may not stabilize. If you have an SG greater than 1.1, your bullet should stabilize under optimal conditions, but stabilization might not be adequate when temperature, altitude, or other variables are less-than-optimal. That’s why Berger normally recommends at least 1.5 SG to get out of the “Marginal Stability” zone.

In his book Applied Ballistics For Long-Range Shooting, 3rd Ed., Bryan Litz (Berger Ballistician) recommends at least a 1.4 SG rating when selecting a barrel twist for a particular bullet. This gives you a safety margin for shooting under various conditions, such as higher or lower altitudes or temperatures.

Anti-Hunting IP28 Ballot Initiative Fails in Oregon

Oregon IP28 ip 28 anti-hunting fishing ballote initiative

An Oregon anti-hunting ballot initiative opposed by NSSF®, The Firearm Industry Trade Association, failed to gather enough certified signatures to be considered by voters. Oregon’s Initiative Petition 28 (IP 28), called the “People for the Elimination of Animal Cruelty Exemptions (PEACE) Act,” was proposed to prohibit and criminalize hunting, trapping and livestock production.

The proposed ballot initiative was disqualified by the Oregon Secretary of State’s Elections Division for consideration by voters on November 3, 2026, after it gathered just 104,262 valid signatures, below the threshold requirement of 117,173 required signatures.

“This radical anti-hunting plan was clearly, and correctly, rejected by Oregonians who wanted no part of this attack on the heritage of outdoorsmanship and proven conservation efforts that managed hunting requires,” said Lawrence G. Keane, NSSF Senior Vice President & General Counsel. “The proposal would have, without question, destroyed Oregon’s rural communities, outdoor economy and abundant wildlife. Hunters are the original wildlife conservationists and are crucial to sustained propagation of managed wildlife for future generations. Oregonians are correct to reject this short-sighted and politically-driven agenda that would have annihilated over a century’s work to restore wildlife across Oregon’s landscape.”

NSSF strongly opposed IP 28, which was pitched to voters as a measure to strengthen state animal cruelty laws. However, Oregon already punishes animal cruelty. IP 28 would have removed legal protections for regulated hunting, fishing, ranching and other lawful activities that are critical for wildlife management, culturally rooted and economically important across the state.

Further, IP 28 would have threatened the funding structure that supports wild game and nongame species alike. In fact, 85 percent of Oregon’s wildlife money comes from the combination of excise taxes paid by firearm and ammunition manufacturers and hunting license, permit and stamp fees. The U.S. Fish and Wildlife Service (USFWS) apportioned $1.3 billion to state wildlife agencies last year. Over $804 million of that is sourced directly from the Pittman-Robertson excise tax paid by firearm and ammunition manufacturers. Oregon received over $9.7 million from that apportionment.

The Oregon Department of Fish and Wildlife (ODFW) reports that hunting, fishing and wildlife watching accounted for $1.2 billion in spending in 2019, or $1.47 billion when adjusted for inflation. Oregon’s outdoor recreation economy generated $9 billion in economic impact in 2024, supporting more than 76,000 jobs and accounts for 2.7 percent of state gross domestic product.

Make Your Own Spray-On Cartridge Case Lube — Save Money

DIY yourself lanolin case lube lubricant One Shot Ultimate Reloader Gavin Gear 6.5 Guys

Tired of spending $15-$25 for a can of spray lube that doesn’t last that long? For about the same price as a single 10 oz. can you can make your own effective spray lube that should last for multiple seasons and lube thousands of cases quickly and easily.

In the YouTube video embedded below, our friend Gavin Gear of UltimateReloader.com shows how to make your own case lube using simple, inexpensive ingredients. As recommended by the 6.5 Guys, this Liquid Lanolin + Isopropyl Alchohol mix works well and is very cost-effective. You can make a pint of this home-brew Lanolin case lube that will lube thousands of cases — many more than a typical commercial aerosol spray can (that’s mostly compressed air).

Complete Case Lube Instructions on UltimateReloader.com »

Gavin tells us: “Per the 65guys instructions, I ordered the same components and spray bottles, and these worked out great”:

1. Swan Isopropyl Alcohol, 99%, Pint, 16 Ounce (2-pack)
2. Home Health Liquid Lanolin, 4 Ounce
3. Chemical Guys ACC_121.16HD-3PK Chem. Resistant Heavy Duty Bottle/Sprayer (16 oz.)

Gavin describes the exact mixing process on his Ultimate Reloader website. Gavin says this lube mix is a good complement to the Hornady One-Shot (pistol) and Dillon DCL (rifle) lubes he has used for pistol and rifle reloading sessions. CLICK HERE to read more.
