[QUOTE="lazylabs, post: 1082280, member: 6641"] So everyone is familiar with long vs short throating for specific bullets. For arguments sake say we are going for full dia bullet base seated to the bottom of the case neck. Now say for a given round the bullet starts tapering .300 past the case. We can measure and make all that work.... With a bullet 20gr heavier and same relation to the lands it may protrude .050 deeper in the case. So what angular relationship do you maintain between bullet taper vs throat angle? Change per bullet? How many shots until the erosion negates any matching? [/QUOTE]
