[QUOTE="Bart B, post: 577899, member: 5302"] Friend of mine back in the early 1970's had a collet made to fit the ogive of some 30 caliber 185-gr. match bullets. The collet was chucked up in a Dremel Tool with an ampmeter in line with one side of the electric cord. Bullets were spun at 30,000 rpm. A few were so unbalanced they flew out of the collet bouncing off walls, ceiling and people. The perfect balanced ones drew the least current and several dozen were set aside for testing. He clamped his Hart barreled pre-'64 Win. 70 in a machine rest then tested his loads at 600 yards. Some of the 10 shot groups were barely under 7/10ths inch; close to 1/10th MOA at 600 yards. The other groups were all under 1.5 inches. Then a 40-shot group was fired and the all went into 1.92 inch. Not bad at all for full length sized cases and perfectly balanced bullets. [/QUOTE]
