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. […]
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 […]
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 […]
As an avid watcher of shows like “American Pickers” and “Pawn Stars” – I’m aware of the fact that antique values and prices frequently have nothing to do with how “cool” something is or the quality of the item, but rather the rarity of the item. Some antiques are expensive and poor quality, and some […]
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 […]
I’m the kind of guy that likes to get tool and shop “systems” setup and dialed-in before undertaking projects, and for daily tasks as well. Until recently, I had to bolt down reloading presses on my steel pedestal to use them. That created a lot of extra work to switch between tasks, and also prevented […]
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 […]
Thanks everyone for your patience while we’ve been out of stock on our ergonomic roller handles and bullet trays for the Hornady Lock-N-Load AP. These items are now in-stock! You can find out more and order them here: Ultimate Reloader Combo Pack for Hornady Lock-N-Load Ultimate Reloader Modular Bullet Tray System for Hornady Ultimate Reloader […]
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 […]
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 […]
If you spend much time online, you’ve probably at least heard of the online forum http://thehighroad.org This is one of my favorite forums for a couple of reasons: There’s a lot of traffic and good information The members and staff are both knowledgeable and cool to deal with The Handloading and Reloading forum is where […]
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 […]
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
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 […]
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 […]
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 […]
