[QUOTE="MudRunner2005, post: 1432400, member: 12995"] Man, you're response is so 1950's... High-tapered & low shoulder angles for positive extraction, despite most dangerous game cartridges have had a belt for over 100 years for that exact reason, despite most being nearly straight-walled, and not knowing that combustion science has proven that greater shoulder angles have better combustion for increased velocities, longer dwell times for more complete combustion, lower flame angles for better throat life, and less taper proves to grab the chamber walls better to reduce lug pressures, which will increase action life and brass life, and reduce brass growth for less, if any, trimming through the life of your cases... But I guess they don't teach that in 1950... :cool: [/QUOTE]
