Rifle Kraft

This target is a modification of the well known Rifle Kraft or "Kraft" target. The original can be found here: Rifle Kraft.

Design & Setup

1. Determine if the drill will be shot under time constraints (its up to you).
2. Determine which positions the drill will be shot from (you can work on them all at once, a few at a time, or just one).
3. Setup chosen positions 100 yards from the target.

Course of Fire

1. Shoot a single shot from each position.
2. Go back to the start.
3. Shoot a single shot from each position again.

Analyze Results

Where did your worst shot land? This is your "Kraft Number" or a true reflection of how accurate you are while shooting positionally.

For example, if your worst shot lands in the 5 MOA ring, this means your shooting system (you + rifle) is accurate to within 5 MOA. Wait, what if all shots land in the 1 MOA ring except one that fell in the 5 MOA ring (the proverbial flyer)? It counts. The target is telling you that your system is accurate to within 5 MOA.

In order to learn, it is important to be honest with your results. The whole point of this diagnostic tool is to determine where your weaknesses are. Maybe it's a certain position. Maybe a bad shot was rushed due to time constraints. Maybe your load is inconsistent. Maybe your rifle needs adjustment. Maybe you can figure out how to gain extra stability somewhere. Maybe your technique in general is bad. Maybe your fundamentals are bad. All of this is lost if you throw away shots. That flyer went there for a reason. Trying to determine why is the whole point.

Features:

• Has 1/4, 1/2, and 1 TrueMOA squares for a quick visible reference of group size.
• TrueMOA squares are rotated to form diamonds to aid in aiming.
• Has 1/10 MIL hash lines to match scope turret clicks for an easy way to zero.

How to Print:

Simply print or send to a printing service. It is important to not let your printer or printing service re-size the page. Many printers have a "Scale to Fit" feature to dynamically size the sheet to a single piece of paper. It is important to turn this and any other sizing features off. Notifications about margins, etc should be ignored. It helps to print in color, but it works ok in B&W.

How to Validate Target Print:

Once you have a print in hand, measure the following to validate your print came out properly sized.

• 1 MOA Diamond should measure 1.0472" in diameter.
• 1/2 MOA Diamond should measure 0.5236" in diameter.
• 1/4 MOA Diamond should measure 0.2618" in diameter.
• Each 1/10 MIL square should measure 0.36" in diameter.

Keep in mind that the proper way to measure groups is to measure to the outside of the widest part of the group and deduct the caliber of your bullet. For example, 0.500" group width - 0.243"(6mm) bullet = 0.257" Group Size. The diamonds above do not account for your bullet diameter. I may try to work up some versions that are adjusted for specific bullet diameters at a later time.

How to Use Target:

It is important that the target be setup at 100 yards from your shooting location to make all the math work. Once you shoot your groups, a simple eyeball will let you know if it is a 1/4, 1/2, or 1 MOA group. Zero a little off? No problem, just move your elevation and windage turrets the same amount of 1/10 squares you are offset by (assuming your turrets have 1/10 or .1 MIL click adjustments). This can even be done at a later time without requiring validation rounds.

Gordon's Reloading Tool is an excellent load analysis scientific modeling tool. It was recommended to me by my Gunsmith (Jed Mercer of Nash Precision) and after trying it, I have to agree that I find a lot of value in this. From a validation standpoint, I put my current 6mmGT load information into the program and the output is dead nuts (just a single ft/s difference) accurate to known current velocitity. Best of all, this application is free. I understand that Mr. Gordon passed away recently, but plans are in the works to hand off development to a new team. Can't recommended this software enough.

How to Download

Navigate over to the website at grtools.de and select the download link at the top of the page. Once you create an account, the binaries will be available for download.

On Windows

Within the download package, there is a GordonsReloadingTool.exe binary that will launch the program. The application does not need to be installed, it runs from the folder and does not require elevated permissions.

On Mac

Since this application is a compiled binary for Windows, one needs a workaround to run on a Mac. The normal options apply here. As a Mac user, I am partial to CrossOver by CodeWeavers. (GRT runs great on CrossOver!)

Getting Started

I will admit, the interface does look rather complex (but cool). However, the learning curve is very short. All you really need to do is select case, powder, and bullet then plug in your values for each. Stuff that needs to be adjusted is generally colored yellow. It is very important to set case capacity and bullet length for your specific values and not use the default values.

Validation

It is also very important to validate the output data. I would measure, then re-measure, if you see any significant inconsistancies.
