Happy New Year! This is the first update of 2020!

I hope everyone had a wonderful holiday break. I certainly did. I took the time to work on some planning for the website, project planning, and visiting with family. Hopefully there will be some new and exciting content for this upcoming year.

2020 SHOT Show is right around the corner and there has already been some interesting new developments with new cartridges being rumored. As details emerge we will be sure to take a closer look.

In the meantime we did do a few site updates prior to leaving for the break. Most of the work has been centered on the Photogrammetry Drone. We worked through the initial CAD modeling of the Drone and then started using some basic Computational Fluid Dynamics (CFD), offered by Solidworks to begin to see how the drone will glide through the air. You can read the write up on this at the link below.

Photogrammetry Drone: CAD Modeling

We also go the official go ahead to do an initial parts order for the drone. So here is the parts we’re going with and an explanation as to why I decided to go with these parts. The write up can be found at the link below.

Photogrammetry Drone: Initial Parts Ordering

In the next few weeks we will have several write ups on more fundamentals of cartridges, their design and their manufacture. With Sig Sauers announcement of the 277 Sig Fury, it will be important to understand the strengths and weakness of existing cartridge technology before we can appreciate what Sig is trying to accomplish here. Hopefully it will be adopted by SAAMI soon so we can have an industry standard spec, if not we may need to go to CIP.

Another Monday, the last Monday before Christmas. Have you got your holiday shopping done yet? Me neither.

This past week was quite busy, but we still managed to get a few write ups done, and cross a few things off the ToDo list. We received the wrecked Ebee from the repair shop, in pieces, and we did a quick look at the parts that go into the Ebee and see if there’s anything that would be hard to replicate in our own drone.

Photogrammetry Drone: Examining Wreckage

We also finished putting together the airframe for our own drone. There is much to be done with this drone, but this is a good first step.

Photogrammetry Drone: Airframe

Turning back to the reason for the website, we were able to process some scrap lead into ingots. Unless you’re starting with clean lead, this is usually the first step in casting your own bullets. Here’s how we do it.

Turning Scrap Lead Into a Resource

That’s been our week. I’ll be taking a holiday break for 2 weeks, so there will be no new updates during that time. I’ll expect to have new updates by the second or third week of the new year. Thanks again for being a subscriber, and we hope to continue to bring you interesting content through 2020!

There’s only a few more weeks left to the year. The website has been live for a little 3 months and has garnered 4,000+ views. Thanks to everyone who had taken a moment to check out the site, and hopefully you’ve enjoyed the content so far.

These next few weeks will be busy for me. Many of you know I have been working on getting my EMS Basic license, well the testing for that will be this weekend. If all goes well I’ll start running with the local volunteer ambulance service. Couple that with holiday preparations and my time is becoming extremely limited. There will likely be only a few updates between now and the end of the year.

Last week we did make some time to take a deep dive into some of the popular new cartridges on the market. What they are, why they exist, and a deep look as to whether or not they really are any better than what already exists. You can read that write up here:

Why a New Cartridge?

As I mentioned at the end of the write up, this was a fun article to write and I may do similar write ups in the future. Sometimes it can be hard to cut through the marketing hype to understand what a new cartridge does, we’ll try to make sense of it in these write ups.

Happy Cyber Monday! We don’t sell anything here at The Ballistic Assistant, but we know there’s some pretty awesome deals to be had, don’t forget to check out Brownells, Midway USA, JD Guns N’ Gear and others.

This past week we released a few write ups, mostly dealing with our Pawn Shop 30-06. We were able to mount the scope base and take it out for some range time.

Pawn Shop 30-06: Scope Base

Before we can start to improve accuracy we need to establish a baseline, something to work from. Here’s how we go about doing that.

Pawn Shop 30-06: Accuracy Testing – Baseline

We used Remington Hog Hammer loaded with Barnes 168gr TSX bullets. Having done plenty of testing with Barnes bullets, I know that the bullets can perform. So how did the rest of the load do?

Pawn Shop 30-06: Ammo Eval – Remington Hog Hammer

We continue to work on the 3D Printer. Progress is likely going to slow down over the holidays, but we are working to get this thing built. Here we did the machining on the Y and Z Axis Lead Screws.

3D Printer: Y and Z Axis Drives

We’ve has a few pretty decent snow events over the last few days and it’s been fairly cold. As weather allows will be a few more trips to the range in the coming weeks as we need to sight in the VZ-58 and do some trigger work on the Pawn Shop 30-06.

We hope everyone is enjoying the holiday season so far, as always, if there’s questions or comments you can email me directly at jayandrew338@gmail.com or check us out on Facebook.

Good Monday Morning! This past week went by fast for us. As a consequence we did not get as much done as we would have liked. In the United States this week is Thanksgiving, which shortens the work week from 5 days to about 3, (Except those working in Retail. Been there done that, sorry guys).

We’ll be posting a few articles this week. We went to the shooting range to sight in the Pawn Shop 30-06 Mauser. Some exciting results there, so look for an article on that this week.

In the meantime here’s what we published over the past week.

Along with the theme of the Pawn Shop 30-06 we are taking another scrap Mauser Action and turning it into something of a scout rifle. This is along the lines of Jeff Cooper’s vision of the ideal rifle. Compact, lightweight, and capable of taking game up to 1,000lbs.

Junk Mauser to 308 Scout Rifle: Introduction

This next project is a complete departure from the theme of the site. However I thought it was too cool of a project not to write about. This is something I am doing for work. We have been using an eBee drone for all of our aerial surveying needs at the mine, but due to the high operating cost we are looking at a self built option. I’ll be doing all the Research, Construction and testing of this new bird. If you’re interested here’s the introduction article.

Photogrammetry Drone: Introduction

We have continued to make progress on the 3D Printer. The frame is all but complete, and we’re moving on to building the Y and Z Axis drive train. The frame is probably the most involved subassembly of this build. To see the detailed write up, check out the link below.

3D Printer: Framing

As you can tell I have several irons in the fire, working on a few different projects. This keeps me busy, as I wait for parts to arrive for other projects. Hopefully there is a little something for everyone.

This week has been a busy week for me, and while I was able to make some progress on the projects, I haven’t been able to do a whole lot else. So if there doesn’t seem to be as much of a variety of posts, this would be why.

Fair warning, we in the United States are moving into the Holiday Season. All sorts of chaos ensues during this time of year, and that usually makes money tight, and time short. As a result many of the projects I am working on will slow down. We will be rolling out several new project pages over the next few weeks, some of these will be related to shooting/gun smithing, others will be unrelated to the hobby, but are projects that I am undertaking for work.

Given that the projects maybe slow, I’ll be working on more articles that focus on the manufacturing side of ammunition development and production.

This past week we made some more progress on getting the gremlins out of the VZ-58. Here’s a few write ups on what we did, and how it improved things.

VZ-58: Feed Ramp Addition

VZ-58: Anti-Walk Pins

VZ-58: Steel Case Ammo Issues

A new project that I’ll be working on is getting a old commercial Mauser shooting like it should. We’ll be doing some work on that this week.

Pawn Shop 30-06: Introduction

We introduced the project page for the Junk Mauser to 308 Scout Rifle, but I have yet to provide a formal introduction to that. We’ll be working through that this week. This should be an interesting project.

I hope everyone has a chance to thank a Veteran today. They are truly special people who do not always receive the recognition they deserve. To those that served, thank you!

This past we were able to get out an test fire the VZ-58. Learned a few things in the process. We’re still working through some bugs with this rifle build, so expect o see a few more articles before we can call this project complete.

VZ-58: Test Firing & Installing the Ejector

We continued our discussion on Variation. This time how to visualize it using simple control charts. Hopefully this article will prove beneficial in helping to understand what normal and abnormal process variation looks like.

Visualizing Variation using Control Charts

We continue to make progress with the 3D Printer. There is still some design work left to do, but for the most part the major components have been modeled. I’ve started putting together the pieces for the frame, and we are well on our way to getting something going!

3D Printer: Cutting out the Wood Components

3D Printer: Cooling System First Concept

It’s the last Monday in October. Boy has this year flown by.

Last week was a busy week for me, we’ve been working on the design evaluation and redesign of the 3D printer before we start making chips. Here’s a write up covering that:

3D Printer: Design Change Y-Axis Linear Motion Shafts

The VZ-58 Build is wrapping up, we are installing the last few components in the fire control group. We started with the magazine hardware

VZ-58: Installing Magazine Latch Hardware

For those who are interested more in the manufacturing of ammunition, we kicked off a series of write ups on Variation. This one is an introduction to much of the terminology and measurements use to quantify variation within a data set.

Introduction to Variation

A few months ago I built some tooling for my bullet swage press. I’m was not happy with how rough some of it turned out, so I am rebuilding the tooling so it has a little more polished look. I’ve shared the design, and my build process here.

Bullet Swaging: Draw Die Housing Part 1

Thanks for taking the time to subscribe. You may have noticed there’s a lot of frying pans in the fire, which is good. It allows me to work on a few different things while I wait for parts to arrive.

Good Monday Morning! Hard to believe we are almost through October!

We have had a busy week. I’ve been able to get a lot of work done on the VZ-58 Build. I am at the point where I am waiting on some parts to come in. As I get those parts in I’ll continue to share how that build is going. We are on the tail end of things and I am anxious to get out an put some rounds down range!

VZ-58: Receiver Press Fixture

Updated Barrel Block Prints for the VZ-58

VZ-58: Pressing the Receiver onto the Barrel

VZ-58: Headspacing Correction – My Oops

Since we are wrapping up on the VZ-58 I will be kicking off a few more projects. These are projects that have sat on the back burner for a few years. I’ll be working on them as time and money allows. You’ll find these projects under the projects menu on the home page.

3D Printer: Introduction – Model and Frame

There’s been a lot of focus on the VZ and other projects, but I do not want that to detract from the main theme of the site, looking at internal ballistics. I’ve debated on several ways to try and kick this off, here’s what I came up with as a general overview.

Project Management for Load Development

If you’d like to know the general process from load conception to product release, this is the article for you. This will also introduce the testing that is conducted as part of the Load Development Process. There will be more Write Ups on each test later, so look at this as an introduction.

All of the write ups that pertain to developing a load for the commercial market will be found under this menu option:

Professional Load Development
