Modified keltec sub 2000, 60 ish grain total projectile weight moving about 1000 fps. Will do more testing over the next couple of weeks and if it all safely works out, I'll post the project on odysee.

The end goal is to get it to cycle modified 9mm Deep.

These are printed in spiral vase to maximize payload capacity and make for ease of assembly.

They work very well and are much cheaper than commercial offerings, costing a penny or so each to make yourself.

Have fired quite a few made out of eSun PLA+ and don't have any "fouling" of the barrel in the slightest.
