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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
One of the things I’ve been meaning to do for a while now is to provide a reloading costs calculator so that readers can answer the age old question – “How much will I save if I reload?”. You can find this resource under “Tools” in the info center (left pane on home page) or […]
