Military surplus brass primers are crimped to make the cartridges better able to withstand the rough and tumble wear and tear and weather of infantry life in the field.I have options? Right now, I can't get my hands on a ton of the brass at any price, so I guess I'll consider "cheap" if it works well. I have 500 cases (small rifle primers) of once-fired pick up brass and 95% is crimped.
Why does the military crimp primer holes anyway?
I have never thought of that, but if it works, that's great!! How big of a chuck do you have on your drill? The deburring tools I have seen are too big for any drill I have!!I don't know if the long time reloaders will agree with this but what I did was I chucked my hand deburring tool to my cordless drill and just drilled out the crimp a very little bit. Too much and the shells bad. Very cheap method and very effective.
