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 […]
