Ever wish you could just press a button and get perfectly tuned ammunition? We’re not quite in Star Trek  territory yet but a properly set up reloading bench is about as close as the shooting world gets. At Redleg Guns , we build precision rifles and develop ammunition every day not just for fun, but for hunters and marksmen who demand repeatable accuracy in the field and on the range. One thing we see over and over is this: most reloading mistakes aren’t caused by carelessne

You’ve got your chronograph humming, and you’re chasing that single-digit SD. But then you see it a 42 fps outlier in an otherwise perfect string and you start questioning everything from your scale to your soul. Let’s break down what actually  causes inconsistent velocity, how to fix it, and where your time and money make the biggest difference. 🔬 Understanding Velocity Spread Extreme Spread (ES)  is the difference between your slowest and fastest shots. Standard Deviation

Small Primer Left, Large Primer Center, Large Primer Right When it comes to custom rifle performance, reloaders know the primer isn’t just a spark it’s the foundation  of the entire ballistic cycle. At Redleg Company Inc. in Chandler, Minnesota , our precision rifle builds and reloading instruction are rooted in understanding every variable that affects consistency, safety, and velocity. And few factors have as much subtle impact as the choice between small rifle primer (SRP)

You’ve perfected your load. Every charge meticulously weighed, every primer seated to spec. Your rifle holds sub-MOA groups like clockwork until one humid August morning when your chronograph says otherwise. Sound familiar? That’s not bad luck. That’s humidity , quietly shifting your powder’s burn rate, pressure curve, and ultimately, your rifle’s point of impact. Most reloaders focus on temperature , but humidity the water vapor in the air plays just as critical a role  in a

Redleg Company Inc. – Chandler, Minnesota | Where Precision Meets Unyielding Science The Overlooked Overlord Inside Every Cartridge In the world of precision reloading where every grain, seating depth, and brass volume is controlled there’s one variable that silently destroys consistency: powder temperature . Even the most experienced marksmen, from long-range competitors to seasoned hunters, often underestimate its impact. A load that’s safe and precise at 70°F  can spike 10

Longevity. Consistency. Precision. Whether you're hunting the open country of somewhere USA, banging steel at a PRS match, or reloading...

“Can I do load development while fire-forming new brass, or should I fire-form first?” The short answer? Yes you can do both. But like everything in precision shooting, execution and context matter . Let’s break it down with practical examples. 🔥 What Is Fire-Forming and How Does It Affect Load Development? Fire-forming is the process of reshaping brand-new or reformed brass to match the exact contours of your rifle’s chamber. That first firing “sets” the brass, especially t

What Exactly Is Case Volume? Case volume is the internal capacity of your brass cartridge —how much space there is inside the case to hold powder. Here’s the catch: not all brass has the same volume, even if: It’s from the same manufacturer. It weighs the same. It’s been prepped identically. Small differences, just a few tenths of a grain of water capacity, can cause measurable shifts in MV. Those velocity shifts show up as vertical stringing downrange. Why Case Volume Affect

Reloaders, hunters, and precision shooters are always chasing tighter groups and more consistent velocities.  One hotly debated topic in the reloading world is this: "Does weighing your brass cases actually make a difference?" At Redleg Guns , we’re all about practical precision not internet hype. So we decided to put this question to the test with real-world data  to help you decide if sorting your brass by weight is worth your time. 🔍 Why Reloaders Weigh Brass Cases and So

What Is Base Diameter and Why Should You Care? The base diameter is the width of the cartridge case just above the extractor groove, which is the thickest and strongest part of the case body. This area experiences high pressure during ignition, and how much it expands can tell you a lot about: Chamber dimensions (Are you in spec?) Load pressure (Is it too hot? Safe?) Brass quality (Is it stretching too much?) Sizing consistency (Are you over- or under-sizing?) If you’re

For elite shooters and reloaders, precision isn’t just about tight groups it’s about engineering ammunition to perform under 70,000 psi and 3,000°F in milliseconds. Concentricity, often reduced to a static runout measurement, is a dynamic system of geometry, metallurgy, thermodynamics, and mechanical precision. This guide dives deep into concentricity, providing advanced diagnostics, quantifiable metrics, and a case study showing how to transform a 6.5 Creedmoor from 0.5 MOA

Every precision shooter knows their brass, powder, and bullet get all the attention. But the humble primer the smallest part of the cartridge can make or break consistency. At Redleg Guns, we’ve tested thousands of loads to uncover how primer choice, seating depth, and uniformity impact accuracy When it comes to fine-tuning precision reloads, shooters often pour hours into bullet selection, powder charge weights, and case prep but they miss the most sensitive and mechanically

In precision hunting, bullet selection isn't just about brand preference it's about terminal performance under specific conditions. For reloaders and long-range hunters running custom rifles, understanding how different bullets behave at various distances and especially on tough, bone-crushing hits is essential. At Redleg, we’re constantly asked: “What bullet should I use for elk, mule deer, or bear especially if I might shoot anywhere from 75 yards to 600?” This is your comp

When it comes to reloading, few decisions are more critical than powder selection. The burn rate  of a smokeless powder how fast or slow it burns under pressure is a key factor that interacts with caliber , barrel length , and bullet weight  to influence everything from velocity and pressure curves to accuracy and recoil. This guide is designed to help reloaders understand the science behind powder burn rates and how to make informed decisions when selecting powders for custo

When building or buying a precision rifle, one of the most overlooked but very critical factors  is the barrel’s twist rate . At Redleg Guns, we believe your rifle should perform like a precision instrument, not a guessing game. That means matching the right twist rate  to your intended use, caliber, and bullet weight. But what is twist rate and why does it matter? 🌀 What Is Barrel Twist Rate? The twist rate  is the speed at which the rifling inside your barrel spins the bul

In the world of precision shooting, it’s not enough for a rifle to “shoot well” it needs to shoot your load well , and do it consistently . Whether you’re hunting coyotes across the fields of Southwest Minnesota or ringing steel at 1,000 yards, finding your rifle’s ideal load or accuracy node can be the difference between a solid hit and a frustrating miss. At Redleg Guns, we live and breathe precision. In this guide, we’re digging deep into: The difference between Ladder Tes

🔧 CHAPTER 1: PRIMER SEATING The primer might be small, but it’s where the shot starts literally. Inconsistent primer seating can cause hangfires, erratic ignition, vertical stringing, or complete failures. Precision reloaders treat primer seating as carefully as they do bullet jump or powder charge. 🧪 1.1 Understanding Primer Pocket Fit & Tension Brass undergoes metal fatigue after multiple firings. Every time you fire a round, the pressure inside the case tries to push the

In precision shooting, brass prep is where accuracy begins. It’s the first and arguably most critical step that dictates how well your reloads will perform in the real world. Whether you’re building loads for a match-grade bolt gun or a custom AR platform, the fit of your brass to your specific chamber is everything. In this post, we’re diving deep into resizing techniques with an emphasis on chamber-specific brass control, neck tension, and measuring tools that separate casu

When you’re chasing precision, annealing brass cases isn’t a luxury it’s a non-negotiable. Whether you're loading for PRS, F-Class, hunting Dall sheep at altitude, or just squeezing every bit of life from Lapua brass, proper annealing controls one of the most overlooked variables in precision shooting: neck tension. 🔬  The Why: Grain Structure & Work Hardening Every time you fire and resize a brass case, you’re cold-working the metal compressing and stretching it.
