I loaded Blue Magics and green RTL Premiers for years, using C300, 700X, and Clays. If you kept your speed down to 1200fps or less, 15 reloads wasn't out of the question. After about 10-12, they got black and crispy on the crimp, but still loaded okay. The old RXP was good for about 8-10, then the crimp was burnt and cracked, and unusable.
