Your Personal Reloaders Logbook

Reloaders Log Overview

What is Reloaders Log ?

This article may be used as a base to any blog post or article you would like to add to your site. All I ask is for you to let me know so I can link to it from by blog.

Do not use any of the loads shown in the images below, they are fully made up as sample data
Whether you reload your own ammunition as a hobby, for economic reasons, accuracy or all of the above - you should have some form of log book to keep track of the performance and costs of the different components and powder weights you use.
The logbook usually comes in the form of a personal spreadsheet/database or pieces of paper for each different component combination that you as a reloader have created yourself. Over time as you try more and more combinations you soon realize that what you are using becomes more and more cumbersome. From my own experience of the spreadsheet that then turned into paper per combination, I found it very difficult to manage as I tested more loads.

Having many years of software development behind me, I knew there was a better way to manage this information and actually get summarized report information back out as a bonus.
I have done development for every platform from web, desktop computer to mobile (Android) and decided that a fully Cloud/Web based application would be the best option as web based software is quicker to write and easier to maintain if written correctly.

Reloaders Log started out as a web based application for me to track my load information myself, but with a few tweaks I was able to make it available to anyone on the internet in a hope to make their reloading logbook easier to manage and maintain.

In the following sections I will give you a overview of the features available. Currently as it stands there is a free version and a premium version available to users - the main difference is the premium version allows for inventory management aswell as a few other smaller features.

Overview and Dashboard

The main idea behind how you manage your reloading information is based on the four components you use (bullets/primers/brass/powder). Each row of information on the Dashboard is a combination of each component (eg.ADI AR2206H, Remington Brass, CCI - 400, 55gr Hornady SP) will be one type of load. Other information available for each load is how many variations you have, these are based on the Powder Weights and COLs, how many results you have collected and how many rounds you currently have loaded.
Your loads on the Dashboard can also be grouped by a Status which will group them together for easy management.

There is also a gun section where you enter some basic information about a gun you will use in the reload testing. You can keep track of your barrel log here aswell with information like date, description, bullet weight, number of shots and a running total.

Load Group and Range Results

For every combination of components and powder weights, you will want to record the actual results you get at the range.
With Reloaders Log this is as simple as selecting the Load Group (component group) and clicking the "Add New Range Test For this Load Group" button.
You will be presented with a dialog that allows you to enter such information as date, the range name, gun, distance, group size and shots fired. Additional information like temperature, wind speed and notes can also be added.
If you wish, you can also attach a scan/photo of the target to the result.
One unique field you have is what we call Confidence, you can enter how confident you were with the results you got on that test - this will be used in reporting at a later date.

A unique addition to the "Load Group" page is the ability for you to get an up-to-date PDF (print out) for any load results (we suggest you use the Grid styling layout). This allows you to keep a offline version in a folder somewhere. The layout of the PDF is based on the gun you used and has a sidebar of the components and powder weights.

The "Load Group" page also will give you a estimate of the cost of that load variation and the number of rounds you could make based in the available amount of materials if you have inventory relating to it.


Keeping track how much powder you have available or how many components you have left for use in any new rounds you would like to create is made a lot easier with a simple inventory list broken up into the four components. When you purchase new components you have the ability to attach the batch number to it for later reference. Items are automatically removed from inventory as you use them, except for brass, where you have the option of removing it from inventory - this will depend on how you would like to track the use of your brass.

"Your Loads" main inventory page will show you all the ammunition you currently have made up aswell as the cost, how many times the brass had been used and a new internal batch number for what you just created.
Within the component pages of the inventory you can also expand a item to see on which loads it has been used and if it has been test or not.


The "Load Overview" report is one of the main reasons this site was created. All load components, COL's and powder weights are displayed in a very simple grid type format, making it very easy for you to see what configurations give you the best results. Due to a few requests by users this report is now available as a downloaded PDF so you can print it at any size you wish (just print with the "fit to page" option).

Database Management

Reloaders Log maintains its own internal databases for most currently available components on the market. Because we know to get all components is impossible, users have the ability to add anything that is not currently stored within our databases, this goes for people who also like to make their own bullets. Any items you add to the databases will only be available to you the user, no-one else will be able to see it. If we notice that you have added a component that will be of benefit to all users (eg. you have added a new bullet by Hornady that has just come on the market), we will make it available to all users so as not to get duplicates.

At the time of writing this article we have (2012-03-11):
266 types of Brass
1239 types of Bullet (16 Manufacturers)
35 types of Primer
148 types of Powder


As with all cloud based applications, you have a area where you can manage your login and security details. The "Profile" also allows you to set the default page size for PDFs of your loads and layout style.
If you find you need a place to put extra data that you track about a load, you have the ability to add custom fields to the load data dialog - these fields will only appear on your load information.


A recent addition to our site that is available to anyone (no account required) is the generation of targets specifically designed by you. You can select you page size, target style, the number of rings, the number of targets on the page and sizing of rings information. We also give you the option to put a grid behind the targets as an addition.
Over time we will be adding many more target styles (at the time of writing we have circle, square and diamond styles).

Blog News Feed / Twitter

Reloaders Log also has a companion blog site, we give you site update information, interesting links and videos via this feed. The blog posts are also visible on the right side of the Dashboard aswell as a few other pages for people who don't visit the blog itself.

Updates are also issued via the Twitter feed ( @ReloadersLog ). Any questions can also be asked in addition to general conversation via this feed is possible (We are New Zealand based - so our time zones may be a little out).


#ReloadingChat is an idea that we have been trailing to get people to chat about reloading in real time.

Again Reloaders Log started out as a simple way for me to manage my reloading data as the traditional methods were not cutting it. I hope that it can be of some help to all the people out there who like to reload aswell.

Thank you for you time in reading this article
