Go for it. My ammo is at least as good (better I think) than off the shelf. Aside from that the advantages are many. You get to pick components. You get to pick the loading. You get to practice w/ what you carry...practice like you fight, fight like you practice. You get to cycle many many rds thru your weapons before you need them in an emergency. As for malfunctions any ammo can cause those AND you should be practicing malfunction drills as a common exercise anyway. The price is right so you get to practice much more.
The argument that somehow youll get tagged for your ‘killer’ ammo is not well founded. Who will know if you keep your mouth shut? At any rate if you make the ammo as you should itll have the appearance of factory. I strongly doubt the cops or da will be able to tell yours from factory. I strongly doubt whether theyll even know to look.
If, as people are predicting, things go bad then having the capably to make your own ammo will pay off big...youll be doing business as usual.
Its going to take plenty of time, study and experimentation on your part. Its doable though and the knowledge gained is invaluable.
It wouldn’t be killer ammunition anyway, as it would be a lighter load for my wife. I’ve never been to court, but I have to think the weapon would be confiscated and the topic of ammunition would come up some time during the trial. We have lots of shootings in the Tidewater VA area.
