When it comes to guy time – it’s hard to beat putting a rifle together from scratch! Recently, my good friend and neighbor Dale Miller and I started to put together an AR-15 (his first AR-15) for him from individual parts. I already had the tools and supplies from the AR-MPR build, so putting together […]

RCBS Rifle Bullet Feeder on RCBS Pro-2000 – Some Notes
For a while I have been wondering about the RCBS Rifle Bullet Feeder – and now that I’ve setup and used the 22 caliber kit on the RCBS Pro-2000, I know a lot more about how this tool works, and what it is capable of. Setting up the unit is fairly straightforward, with a requirement […]
AR-MPR – Hornady Lock-N-Load AP Loading 223
Continuing with our coverage of high-volume loading of .223 Remington and 5.56 NATO ammunition for the AR-MPR project, this time we’ll look at using the Hornady Lock-N-Load AP to load for the AR-15. In this video, I’ll show loading in full progressive mode with the use of the Hornady Lock-N-Load Case Feeder system as well. […]
AR-MPR – RCBS Rifle Bullet Feeder on Pro-2000 Loading 223
If you have an AR-15, you know that they tend to chew through ammo very quickly. It’s a lot of fun, but it also gets expensive really quickly, especially if you are requiring match-grade ammunition. The solution is to load .223/5.56 on a progressive reloading press. If you really want to crank it up, you […]
AR-MPR- RCBS Rifle Bullet Feeder Overview Part II
Recently, I gave a quick overview of the RCBS Rifle Bullet Feed System. In that post, I gave an overview of what’s included in the kit. In this post, we’ll take a look at what this system looks like installed on a 5-Station reloading press (The RCBS Pro-2000 in this case). As you can see […]
AR-MPR- RCBS Rifle Bullet Feeder Overview
Phase III of the AR-MPR AR-15 rifle project is really all about “precision mass production” of the ammunition that we’re developing in Phase II (precision single stage loading). There are a couple key things that we’ll explore: first, we’ll look at progressive reloading of .223 / 5.56 ammunition. We’ll also extend our production rates by […]
AR-MPR Phase II – Checking and Correcting Bullet Concentricity
If you are a precision shooter, you care about consistency for the cartridges that you shoot. One of the most important factors to measure and control when reloading match ammunition is bullet concentricity. Simply stated, this is the alignment of the case and bullet. If you have “good concentricity”, you will have the axis of […]
AR-MPR Phase II – Seating Bullets
In this video, we’ll use the Hornady OAL Gage measurements from our first Phase II loading video: AR-MPR: Phase II – Determining Max COL with OAL Gage and measure the dimensions of the cartridge and magazine to determine the optimal bullet seating depth for the bullet and rifle in question. We’ll then use the Redding […]
AR-MPR – OnTarget Software – Measure Groups Easily
For AR-MPR, I’m chasing a .5 – .75 MOA accuracy goal. Initially, I started with 3-shot groups when I function tested the rifle, but have upgraded the challenge to “consistent 5-shot groups at .5 – .75 MOA”. In order to track my progress, I’ve taken a hint from Paul over at http://accurateshooter.com – use the […]
AR-MPR: Phase II – Magpul PRS Stock and XTM Rail Panels Install
One of the important aspects of a precision rifle is the overall rigidity of the entire rifle – the action, barrel, stock, and other components – the entire unit must be solid in order to shoot with maximum precision. The AR-MPR rifle was initially put together with an M4-Style 6 position collapsible stock. This imposed […]
AR-MPR: Phase II – Charging Cases with the Redding 3-BR and Hornady Auto Charge
In this video we’ll continue the precision loading process by using the Redding 3-BR powder measure and the Hornady Auto Charge to dispense powder loads. Next, we’ll cover calculating optimal seating depth, and seating the bullets. Thanks, Gavin http://ultimatereloader.com/wp-content/uploads/2010/11/AR-MPR-logo-wide-small.jpg
AR-MPR: Phase II – Rifle Accurizing Plans
I just read a great article written by Robert Whitley of www.6mmar.com fame that was posted on the http://accurateshooter.com blog: What Makes an AR Accurate — Whitley Offers Answers Talk about good timing! This post helped me plan the first wave of accurizing activities for the AR-MPR rifle. My goal is to remove any factors […]
AR-MPR: Phase II – Sizing Depriming Priming .223 Remington
In this video we’ll start the precision loading process by lubing, sizing, depriming, and priming cases. We’ll walk through the features of the Redding Big Boss II, show how to lube .223 cases, validate sizing die setup, and then size/deprime/prime the cases. Next, we’ll cover charging the cases with the Redding 3-BR benchrest powder measure […]
AR-MPR: Phase II – Determining Max COL with OAL Gage
One of the important things to know before loading rifle ammunition is how far out (shallow) you can seat bullets, and what the optimized seating depth is for a particular bullet for your rifle and shooting application. For AR-MPR Phase II, we’re going for maximum accuracy, and also need to assure proper feed characteristics so […]
AR-MPR: Phase II Hornady Equipment Overview
In my last post, I gave an overview of some of the Redding equipment that we’ll be showcasing during Phase II of the AR-MPR project. I this post, I’ll cover some Hornady equipment that will also be used for this precision loading phase of the AR-MPR project. We’ll cover more Hornady gear (such as the […]

For Phase II of the AR-MPR we will be focused on precision handloading techniques and load development. For this phase of the project, I decided to showcase some of the popular Redding Reloading products that have an outstanding quality reputation. Here, we’ll talk briefly about each of these products. The Big Boss At the heart […]
AR-MPR: Phase II Kick-Off
Now that we’ve build and function checked the AR-MPR rifle (See Brownells Videos for Complete Details), it’s time to move from Phase I (Build) to Phase II – Precision Loading and Rifle Accurizing/Tuning. This rifle has already proven that it’s capable of meeting the original accuracy goal of .5 – .75 MOA (See Range Report […]
AR-MPR 1st Range Report – Unexpected Results
The mission for the first range trip with the AR-MPR rifle was to really do two things: First, it was about function checking the rifle. Second, it was about sighting in the Nikon Monarch 6-24x50mm riflescope. A third and less important goal was to see how accurate I could shoot this rifle based on […]
AR-MPR – Getting Ready for first range trip
Well, I’m pretty excited to be heading to the range to do the function check on the AR-MPR rifle, and get things sighted in. I’ve got a bunch of 20 round mags on loan, and all of the other accessories that I think I’ll need- but I’ll need ammo for sure. Why not break in […]
AR-MPR: Mounting Nikon Monarch Scope and M-223 Mount
In this post, we’ll look at what’s involved in mounting the Nikon Monarch 6-24 x 50mm riflescope to our AR-15 using the Nikon M-223 scope mount. Before we get on with the video, let’s take a look at the finished product: What’s nice here about using the Midwest Industries quad rail handguard, is the “continuous […]
AR-MPR – Nikon Optics Overview
One of the popular sayings amongst video professionals is “Sound is 50% of video”. The point is- many folks focus almost entirely on the picture quality in their videos, and neglect to pay enough attention to getting proper sound in their videos. Why do I mention this here? Well, 50% of a good precision rifle […]
