FP = Flat point, necessary because the tip of one bullet rests against the primer of the one in front of it in the magazine.

SP = Spire point, or "pointed point."

Win. = Winchester

Spfd. = Springfield, after the Armory in Mass.

The killing "power" of any of these can be increased by the use of soft point bullets, etc.
