[QUOTE="Mikecr, post: 2826353, member: 1521"] You guys got the tangent/secant attributes backwards. It's secant ogives that are more sensitive to optimum seating. Berger adjusted their VLDs for a hybrid lineup to make it easier for folks. A hybrid has tangent interface to bearing, but secant/high ogive radius forward to the meplat. A VLD is purely secant. Bullets were swapped more in the past because actual seating testing was not completed in the past. But most reloaders should know by now that full seating testing is prerequisite to best results. There is also merit to flat base bullets shooting better, as hunters generally use barrels that are too short for the cartridge. This, leading to higher muzzle pressures and ugly muzzle release against boat tails. FB bullets muzzle release cleaner and are far easier to stabilize. [/QUOTE]
