[QUOTE="Fiftydriver, post: 776263, member: 10"] Anyone that has studied the theory of "Detonation" realizes how close you can run to that ragged edge and never realize how close you come to doing serious damage to a firearm. The larger the case capacity, the slower burn rate the powder being used, the more dangerous this can be because there is more unburnt powder left in the bore at the point of detonation. That being the point when you reach critical pressures and all powder left in the bore ignites and burns nearly instantly instead of progressively. That is what causes blown primers in best cases and destroyed rifles in worst cases. [/QUOTE]
