A bunch of Lapua 185 grain FMJ rebated heel 30 caliber match bullets were spun 30,000 rpm in a collet to hold them in a Dremel moto-tool. The unbalanced ones often flew out and bounced off the ceiling and walls. The perfectly balanced ones were tested in a 308 Winchester match rifle and the target was 600 yards downrange.
Several 10-shot groups were fired. All groups fired were well under one inch.
