Range Results: AR-308 rifle – getting close to goal

Hey everyone- I’ve had quite a few inquiries as to how the range results are looking for the AR-308 project rifle. I didn’t set a formal accuracy goal for the project, but I would like to see consistent ~0.5″ groups at 100 yards. This involves shooting skills, load development, and time. This last week, I […]

AR-308 – Precision Loading Pt. 4 – Seating Bullets Checking Concentricity

In my last video, I covered priming and charging cases, see AR-308 – Precision Loading Pt. 3 – Priming and Charging Cases. Now we need to seat bullets, and also check/correct for concentricity of the bullet. If we have a consistent charge, a benchrest primer, consistent case neck thickness, and a properly/optimally seated bullet, we’re […]

AR-308 – Precision Loading Pt. 3 – Priming and Charging Cases

In my last post, I walked through the process of using the Redding Case Neck Gage to sort our 7.62×51 (Military 308 Winchester) brass into buckets based on both thickness and uniformity. Below is a picture showing the distribution. The numbers I’m using here (0.016″ +/- .0005″ for example) reference the total variation in thickness, […]

AR-308 – Precision Loading Pt. 2 – Case Neck Thickness and Uniformity

Now that we’ve cleaned, sized, trimmed, and finished the basis brass prep steps, it’s time to sort the brass that we’ve prepped so that we can uses batches of consistent brass for precision loads. We are now at the final stage of brass prep as covered in the brass prep overview post. For this stage, […]

AR-308 – Precision Loading Pt. 1 – Case sizing and trimming

It’s time to start loading some precision 308 Winchester ammo for the LR-308 project! Our rifle is all tuned up and tricked out, and now we need some capable ammunition to shoot. In this video, I’ll walk through the process of validating sizing die setup with the new Redding Instant Indicator, and we’ll see how […]

AR-308 – Brass and Brass Prep Basics

Now that we’ve finished provisioning the LR-308B rifle for the AR-308 project, it’s time to gear up for precision handloading! Before we start loading, we need to get brass, and prep that brass. It turns out that for precision rifle loading, much of the labor and attention to detail is really related to the brass. […]

AR-308 – Redding equipment overview

One of the things I like most about these kinds of projects (AR-MPR, AR-308) is the opportunity to showcase new reloading equipment (new to the market, or new to my shop :)). For the next phase of the AR-308 project, we’ll transition to a focus on precision single stage reloading. This will involve things like […]

AR-308 – 308 Winchester Cartridge Overview

The 308 Winchester cartridge is one of the most popular, flexible, and accurate rifle cartridges in existence. Whether it be for big game hunting, military sniping, competition shooting, or just having fun, the 308 Winchester is well suited and very capable for these applications. The fact that this cartridge is so popular means that brass […]

AR-308 – Millett TRS-1 Scope Install

Following up on the last post covering the Millett Tactical TRS-1 scope, in this video I’ll cover the mounting procedure for this scope using a pair of Millett tactical scope rings (medium height). I’ll also demonstrate the use of the Wheeler Engineering Firearms Accurizing Torque (FAT) wrench. This is a simple scope mounting procedure where […]

AR-308 – Millett TRS-1 Scope Specifications and Details

In my last post, we took  a look at the features and overall fit/finish for the Millett TRS-1 tactical scope. In this post, we’ll get into more details and look at the specs for this scope. When you purchase the Millett TRS-1 scope, you get the following: Scope Dust caps (for objective and eyepiece) – […]

AR-308 – Millett TRS-1 4-16x50mm Scope Overview

One of the most important components of a good long range rifle is the scope. It goes without saying that a scope must hold zero in order for a rifle to shoot tight groups. The quality of the optics, the repeatability and accuracy of the windage/elevation adjustments, and other factors also play a key role […]

AR-308 – Geissele SD-C Trigger Upgrade

A while back, I posted the Geissele trigger install video while building the AR-MPR AR-15 rifle. I liked the Geissele trigger used on the AR-MPR project so much, that I decided to buy one for the AR-308 project – this time a different version. In this video, we’ll remove the factory trigger, and replace it […]
