I have a box that I bought to load in ar15 but realized they were too long in O.A.L to fit in magazine. I can meet anywhere from parkville down to odenton. Willing to trade for some sub sonic 300 blackout bullets or $30 which would save you sales tax.
I tumbled for two hrs with dawn, then rinse and add 9mm cap full of lemi shine and tumble for 2 hrs. I rinsed and let it dry in the sun. Is the corrosion from not rinsing off the lemishine entirely?
Very cool tool! I'm going to have to look into one of those. I was using a threaded glock 19 barrel with 4.5" length. I'm surprised I was able to achieve that velocity with the shorter barrel.
