If you are privy with 3D printing feel free to message me and I'm more than happy to share my design files for remix or personal use.
This tool has saved me much time when sorting bullets by the various lengths in thous that they come with. After selling more than a couple from the Main Board, I figure i's best to move it here.
While measuring a projectiles overall length, I find myself wondering "Am I almost done?". I don't find it to be totally arduous but definitely find myself getting tired of the repetition and speed whilst using digital calipers. For that reason alone, I created a quick design to make a bullet measuring tool that cuts the time to measure projectiles in half. Below you will find pictures and video of what I created.
If this is something that interests you, just like the Shotmarker Sensor Hub case I created, I'm more than happy to make some of these for members of this forum and for BRI members (sans shipping costs for BRI members).
For this design, I am using PETG-GF which adds rigidness to the overall design. There is a knurled tension screw for both the base adjustment and tension of the gauge to the body itself. It uses brass inserts for good tension.
This QBMv1 will comfortably measure bullets from 6mm to .338 and some variants of .375. I do not have any other bullets larger than those stated, so please let me know if you are able to measure anything larger.
For the body only: $30 shipped USA Only
For Body + Digital Gauge: $65 shipped USA Only
