How about starting a thread with a list of the most commonly used acronyms?
Lead on my man. :)
I will kick off a few from the lead heads:
Bullet shapes, Nose and Body
WFN - Wide Flat Nose
LFN - Long Flat Nose
RFN - Round Flat Nose
FN - Flat Nose
WC - Wadcutter
SWC - Semi-Wadcutter
TC - Truncated Cone
RN - Round Nose
SP - Spire Point
TL - Tumble Lube
Bullet Shapes, Base
BB - Bevel Base
PB - Plain Base, also flat base (fb)
GC - Gas Check
These can and often are combined - WFNGC is a Wide, Flat Nose Gas Check bullet.
