Hornady Rifle Bullet Feeder Part 5: Loading 308 for the AR-10

I am known to be a bit of an extremist. If shooting an AR-15 is fun, wouldn’t shooting an AR-10 be more fun? I actually enjoy both, but I do shoot my DPMS LR-308B quite a bit. That means I’m loading 308 Winchester quite a bit, and that’s what this post is about: loading for […]

AR-308 – RCBS Pro-2000 and 30 cal RCBS Rifle Bullet Feeder

Now that we’ve covered the precision loading process for the AR-308 project, it’s time now to move on to progressive reloading. This will enable us to load ammunition very quickly. If we select the right equipment, and are careful and strategic to setup this equipment, we can also attain very high consistency for the ammo […]

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 – 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 […]

AR-308 – LR-308B Rifle Overview

In this post and video, we’ll see exactly what you get in the box when you take delivery of a DPMS LR-308B rifle. I’m always wanting to know what I’m getting before I buy something, so I figured you all would appreciate a comprehensive unpacking write-up for this rifle! Here’s a video showing what’s in […]

AR-308 – Project Phases and Details

Now that I’ve formally kicked-off the AR-308 project, I wanted to take a moment to give a high level overview of what I’ll cover over the course of this project. The goal is to learn about the .308 Winchester / 7.62x51mm cartridge family, take a close look at the DPMS LR-308 rifle platform, and also […]

AR-308 – Loading the LR-308b – Project Kickoff

I’m excited to announce a new project we’ll be working through here on http://ultimatereloader.com that will extend some of what we did with AR-MPR, but this time we’ll focus on the “big brother” to the AR-15- the AR-10 platform, specifically the DPMS LR-308B. For optics, we’ll get an up-close look at the Bushnell/Millett TRS-1 tactical […]

AR-MPR: Build Part 7 – Lower – Buttstock and Mating Upper Lower

In this, the final AR-15 assembly video, we’ll walk through the installation of the takedown pin and the buttstock assembly. Finally, we’ll put the upper and lower together for the first time and establish basic functionality (formal function check to follow in subsequent posts). After all of the planning and work that went into getting […]

AR-MPR: Build Part 6 – Lower – Trigger Grip and Safety

Continuing our way through the lower build steps, in this video, we’ll look at installing the Geissele national match trigger assembly, the trigger guard, the safety selector lever assembly, and the pistol grip. Next, it’s on to the stock and final touches! Thanks,Gavin

AR-MPR: Build Part 5 – Lower – Magazine Catch Bolt Catch Pivot Pin

In this video, we’ll start the assembly of the lower by walking through the installation of the magazine catch, the bolt catch, and the pivot pin. You’ll see a trick for installing the pivot pin that makes use of a dulled razor blade, and a modified section of drill rod. From the video, in this […]
